Technical Field

The present invention relates to a method and a processing device for plant processing of a field of plants, and a field manager system for such a processing device and processing system.

Background

The general background of the invention is the treatment of plants in agricultural fields. The treatment of plants, in particular of the actual crop cultivated, also includes the treatment of weeds in the field, the treatment of insects in the field and the treatment of pathogens in the field.

Agricultural machines or automated treatment devices, like intelligent sprayers, treat weeds, insects, and/or pathogens in agricultural fields based on ecological and economic regulations. In order to automatically detect and identify different objects to be processed, image recognition is used.

Modern agricultural machines are equipped with more and more sensors. Crop protection is to be performed with intelligent sprayers, mainly comprising a camera system for real-time detection of plants, in particular weeds, crops, insects and/or pathogens. Further knowledge and input data is required for deriving agronomically operable actuator commands, such as triggering a nozzle or weed robot for treating the plant.

It is particularly difficult to define when pathogens or weeds need to be treated because of significant yield or quality impact on the crop, or when the ecological impact or cost of treating the product is more appropriate for not treating in a particular area of the plant field.

This missing link creates significant uncertainty for farmers who must set the threshold for manually treating the plant according to their own intuition. This is usually done at the field level, although many influencing factors vary across the field.

Disclosure of Invention

It would be advantageous to have an improved method of plant treatment of a field of plants for improving the economic return on investment and improving the impact on the ecosystem.

The object of the invention is solved with the subject matter of the independent claims, wherein further embodiments are comprised in the dependent claims. It should be noted that the following described aspects and examples of the invention also apply to the method, the processing device and the field manager system.

According to a first aspect, a method for treatment of a field of plants or treatment of plants with a treatment product, the method comprising:

receiving, by the processing device from the field manager system, a parameter package (parameter) for controlling the processing device, wherein the parameter package depends on or is determined based on offline field data related to expected conditions on the field of plants; and optionally receiving a treatment product composition intended for treating a plant further optionally dependent on the parameter package;

capturing an image of a plant of a field of plants;

identifying object(s) on the captured image;

optionally determining a treatment product composition in dependence on or based on the determined parameter package, the online field data and/or the identified object(s);

a control signal for controlling the treatment device is determined based on the received parameter package, the identified object(s) and the selected treatment product composition.

As used herein, plant treatment preferably comprises: protection crops, which are cultivated plants on a field of plants; the elimination of weeds which are uncultivated and may be harmful to the crop, in particular with herbicides; killing insects on crops and/or weeds, particularly with insecticides; and to destroy any pathogens on the crops and/or weeds, like diseases, in particular with fungicides; and regulating the growth of plants, particularly by using plant growth regulators. As used herein, the term "insecticide" also encompasses nematicides, acaricides, and molluscicides. In addition, safeners can be used in combination with herbicides.

In one embodiment, capturing the image includes capturing an image associated with a particular location on or in the field of the plant to be treated in real time. In this way, fine-tuning of different conditions across the field can be performed in near real-time as the process is performed. Furthermore, the treatments can be applied in a very targeted manner, which results in a more efficient and sustainable agriculture. In a preferred embodiment, the processing device comprises a plurality of image capturing devices configured to capture images of a field of plants as the processing device traverses the field. Each image captured in this manner may be associated with a location and thus provide a snapshot of the real-time situation in the location of the field of plants to be processed. To enable real-time, location-specific control of a processing device, parameter packets received prior to processing provide a way to accelerate situation-specific control of the processing device. Thus, decisions can be made on-the-fly as the processing device traverses the field and captures location-specific images of the field location to be processed.

Preferably, the steps of taking an image, determining a treatment product composition, determining a control signal and optionally providing a control signal to the control unit to initiate the treatment are performed in real time during passage of the treatment device through the field or during treatment of the field. Alternatively, control signals may be provided to the control unit of the processing device to initiate treatment of a field of plants, and the treatment product composition or at least one active ingredient of the treatment product composition may be switched or altered during passage of the processing device through the field or during treatment of the field. Thus, the control signal may be configured to switch, adapt or change the treatment product composition or at least one active ingredient of the treatment product composition during passage of the treatment device through the field or during treatment in the field. The treatment product composition may be switched, adapted or changed based on object identification, which may include, for example, object species and object growth stage.

As used herein, the term "object" includes objects in a field of plants. The object may refer to an object to be treated by the treatment device, such as a plant, like a weed or a crop, an insect and/or a pathogen. The object may be treated with a treatment product, such as a crop protection product. The objects may be associated with locations in the field to allow location-specific processing.

Preferably, a control signal for controlling the processing device may be determined based on the received parameter package, the identified object and the online field data. In one embodiment, the online field data is collected in real time, particularly by the plant processing device. Collecting online field data may include collecting sensor data from sensors attached to the processing device or placed in a field of plants, particularly on-the-fly or in real-time as the processing device passes through the field. Collecting online field data may include soil data collected via soil sensors in the field associated with soil characteristics, such as current soil conditions, e.g., nutrient content or soil moisture and/or soil composition; or weather data collected via weather sensors placed in or near the field or attached to the processing device and associated with current weather conditions or data collected via soil and weather sensors.

The term "offline field data" as used herein refers to any data that is generated, collected, aggregated, or processed prior to determination of the parameter package. Offline field data can be collected from outside the plant processing apparatus. The offline field data may be data collected prior to use of the processing device. The offline field data may be data collected prior to performing processing in the field based on the received parameter package. Offline field data includes, for example, weather data associated with expected weather conditions at the time of processing; expected soil data associated with expected soil conditions at the time of treatment, such as nutrient content, soil moisture, and/or soil composition; growth phase data associated with the growth phase of, for example, weeds or crops at the time of treatment; and/or disease data associated with the disease stage of the crop at the time of treatment. The offline field data may also include crop size, crop health, or crop size compared to the size of other objects in the field (e.g., weed size).

The term "spatially resolved" as used herein refers to any information on the sub-field scale. Such resolution may be associated with more than one location coordinate on a plant field or with a spatial grid of a plant field having grid elements on a sub-field scale. In particular, information on a field of plants may be associated with more than one location or grid element on the field of plants. Such spatial resolution on the sub-field scale allows for more customized and targeted processing of the field of plants.

The term "conditions on a plant field" refers to any condition of the plant field or environmental conditions in the plant field that has an effect on the treatment of the plant. Such conditions may be associated with soil or weather conditions. Soil conditions may be specified by soil data relating to current or expected conditions of the soil. The weather conditions may be associated with weather data relating to current or expected conditions of the weather. The growth conditions may be associated with, for example, the growth stage of the crop or weed. The disease condition can be correlated with disease data relating to the current or expected condition of the disease.

The term "processing device" as used herein or also referred to as a control technique may include chemical control techniques. The chemical control technique preferably comprises at least one device for applying a treatment product, in particular a crop protection product like an insecticide and/or herbicide and/or fungicide. Such apparatus may include a treatment arrangement of one or more spray guns or nozzles arranged on agricultural machines, drones or robots for maneuvering through a field of plants. In a preferred embodiment, the processing device comprises one or more spray guns and associated image capture device(s). The image capture device may be arranged such that the image is associated with an area to be processed by the one or more spray guns. The image capturing device may for example be mounted such that an image in the direction of travel of the processing device is taken, covering the area to be processed by the respective nozzle(s). Each image may be associated with a location and as such provides a snapshot of the real-time condition of the field of plants prior to processing. Thus, the image capturing device may take an image of a specific location of the field of plants as the processing device traverses the field, and the control signal may be adapted accordingly based on the taken image of the area to be processed. Thus, the control signal may be adapted to the situation at a specific location of the field captured by the image at the time of processing.

As used herein, the term "identifying" includes detecting the status of an object, in other words knowing that an object is at a certain location but not exactly what the object is, and optionally identifying the status of the object, in other words knowing the type of object that has been detected, in particular the species of the plant, like crops or weeds, insects and/or pathogens. The identification may comprise determining spatial parameters like crop size, crop health, crop size compared to e.g. weed size. Such a determination may be made locally as the processing device passes through the field. In particular, the identification may be based on image identification and classification algorithms, such as convolutional neural networks or other algorithms known in the art. In particular, the identification of the object is location specific, which depends on the location of the processing device. In this way, the processing can be adapted in real time to the local situation in the field.

As used herein, the term "parameter package" refers to a set of parameters provided to a processing device for controlling the processing device for processing a plant. The parameter package for controlling the processing device may be at least partially spatially resolved or at least partially location specific for the field of plants. Such spatial resolution or location specificity may be based on spatially resolved off-line field data. The spatially resolved offline data may include spatially resolved historical or modeled data of a field of plants. Alternatively or additionally, the spatially resolved offline data may be based on remote sensing data for the field of plants or observation data detected at a limited number of locations in the field of plants. Such observation data may include, for example, images detected at certain locations of the field via the mobile device, and optional results derived via image analysis.

A parameter package may refer to a configuration file for a processing device that may be stored in a memory of the processing device and accessed by a control unit of the processing device. In other words, the parameter package may be logic, such as a decision tree with one or more layers for determining control signals for controlling the processing device depending on measurable input variables, such as captured images and/or online field data. The parameter package may comprise one layer relating to on/off decision and optionally a second layer relating to the composition of the treatment product intended for use and further optionally a third layer relating to the dosage of the treatment product desired to be used. Outside of these parameter envelopes, on/off decisions, composition of treatment products and/or dosage of treatment products may be spatially resolved or location specific for a field of plants. In this manner, real-time decisions regarding the context of the processing are based on real-time images and/or online field data collected as the processing device passes through the field. Providing the parameter package before performing the processing reduces the computation time while enabling a reliable determination of the control signal for the processing. The parameter package or profile may include location-specific parameters provided to the processing device, which may be used to determine the control signal.

In one layer, the parameter package for on/off decision may include thresholds related to parameter(s) derived from captured images and/or object recognition. Such parameters may be derived from the images associated with the identified object(s) and are decisive for the processing decision. In a preferred embodiment, the parameters derived from the captured image and/or the object recognition relate to the object coverage. Further parameters can be derived from the online field data that are critical to the processing decision. If the derived parameter is, for example, below a threshold, the decision is to shut down or no processing. The decision is to switch on or process if the derived parameter is, for example, above a threshold. The parameter package may include a spatially resolved set of thresholds. In this manner, the control signal is determined based on the parameter package and the identified object. In the case of weeds, the parameters derived from the image and/or the weeds identified in the image may be based on parameters representing weed coverage. Similarly in the case of pathogens, the parameters derived from the images and/or the pathogens identified in the images may be based on parameters indicative of pathogen infection. Further similarly, in the case of insects, the parameters derived from the image and/or the insects identified in the image may be based on parameters representing the number of insects present in the image.

Preferably, the processing means is provided with a parameter package or profile, based on which the processing means controls the processing arrangement. In a further embodiment, the determination of the profile or parameter package comprises a determination of a dose level of the treatment product to be administered. Thus, the parameter package may comprise a further layer regarding the dosage level of the treatment product. Such dose levels may relate to parameters derived from image and/or object recognition. Further parameters may be derived from the online field data. In other words, based on the profile or parameter package, the processing device is controlled, based on real-time parameters of the plant field, such as captured images and/or online field data, as to which dose of the treatment product should be applied. In a preferred embodiment, the parameter package comprises variable or incremental dose levels depending on one or more parameters derived from image and/or object recognition. In a further preferred embodiment, determining the dose level based on the identified object comprises determining an object type, an object growth phase and/or an object density. Here, the object density refers to the density of objects identified in a certain area. The object type, the object growth phase and/or the object density may be parameters derived from image and/or object recognition, from which variable or incremental dose levels may be determined. The parameter package may include a spatially resolved set of dose levels.

The term "dosage level" preferably refers to the amount of treatment product per area, e.g. one liter of treatment product per hectare, and may preferably be indicated as the amount of active ingredient (comprised in the treatment product) per area. More preferably, the dosage level should not exceed an upper threshold, wherein the upper threshold is determined by a maximum dosage level which is legally allowed according to applicable regulatory laws and regulations with respect to the corresponding active ingredient of the treatment product.

The parameter package may include another layer of treatment product composition with respect to the intended use. In such cases, the parameter package may be determined depending on the expected significant yield or quality impact on the crop, ecological impact, and/or cost of treating the product composition. Thus, the decision whether to treat the field, which treatment product composition should be employed, at which dosage level treatment, based on the parameter package, achieves the best possible result with respect to efficiency and/or efficacy. The parameter package may include a barrel recipe for a process product barrel system of the processing device. In other words, the treatment product composition may represent a treatment product amount provided in one or more barrels of the treatment device prior to performing the treatment. The mixture from the one or more barrels forming the treatment product may be controlled on the fly depending on the determined composition of the treatment product. The treatment product composition may be determined based on the object identification, which may include, for example, object species and/or object growth stage. Additionally or alternatively, the parameter package may include a spatially-resolved set of treatment product compositions for intended use.

The term "efficiency" refers to the balance of the amount of treatment product applied and the amount of treatment product effective to treat a plant in a field of plants. How effectively the treatment is performed depends on environmental factors such as weather and soil.

The term "efficacy" refers to the balance of positive and negative effects of the treatment product. In other words, efficacy refers to the optimum value of the dosage of treatment product required to effectively treat a particular plant. The dosage should not be so high that the treatment product is wasted, which would also increase costs and negative effects on the environment, but not so low that the treatment product is not effectively treated, which may result in the plant being immunized against the treatment product. The efficacy of the treatment product also depends on environmental factors such as weather and soil.

As used herein, the term "treatment product" refers to products used in plant treatment, such as herbicides, insecticides, fungicides, plant growth regulators, nutritional products, and/or mixtures thereof. The treatment product may comprise different components including different active ingredients such as different herbicides, different fungicides, different insecticides, different nutritional products, different nutrients, and other components such as safeners (particularly in combination with herbicides), adjuvants, fertilizers, adjuvants, stabilizers, and/or mixtures thereof. The treatment product composition is a composition comprising one or two or more treatment products. Thus, there are different types of e.g. herbicides, insecticides and/or fungicides, which are based on different active ingredients, respectively. Since the plant to be protected by the treatment product is preferably a crop, the treatment product may be referred to as a crop protection product. The treatment product composition may also comprise additional substances mixed with the treatment product, such as, for example, water, in particular for diluting and/or thinning the treatment product; and/or nutrient solutions, particularly for enhancing the efficacy of the treatment product. Preferably, the nutrient solution is a nitrogen-containing solution, such as liquid Urea Ammonium Nitrate (UAN).

As used herein, the term "nutritional product" refers to any product that is beneficial to plant nutrition and/or plant health, including but not limited to fertilizers, macronutrients, and micronutrients.

Another treatment product composition may be most promising for each location in a field of plants based on the determined parameter package when performing the described method or when performing a treatment of a field of plants. Preferably, a treatment product composition for treating a plant, insect and/or pathogen can be switched, adapted or changed to another treatment product composition. Thus, a variety of different types of treatment product compositions can be used to treat different locations in a field of plants.

In one embodiment, determining the control signal comprises generating a drum actuator signal and a treatment arrangement signal to control the determined release of the treatment product composition. Upon determining or generating the control signal, a drum actuator signal can be generated that controls an actuator of the treatment device to release the treatment product composition from the drum system. Furthermore, in generating the control signal, a treatment arrangement or nozzle signal can be generated which controls the release of the treatment product composition on the field, preferably at a defined dosage level.

In a further embodiment, the processing device comprises a processing arrangement with more than one nozzle, wherein the processing arrangement signal individually triggers the one or more nozzles. In this way, decisions based on, for example, thresholds of treatment or non-treatment as specified in the parameter package may be taken on an individual nozzle basis.

In one embodiment, the processing device includes a bucket system having more than one bucket. A separate cartridge may include one or more active ingredients and/or additional components, such as water or part(s) of a formulation. Such systems allow for switching or changing the active ingredients or treatment product composition during treatment. The drum may be equipped with a controllable actuator to release at least a part of the drum content or an amount of the drum content, as required for a dose level, for example. The barrel actuator signals can include actuator signals for each barrel to control release from each barrel to form the treatment product composition. Thus, the drum actuator signal may be derived from the determined treatment product composition.

Determining the treatment product composition can include determining the treatment product composition based on the captured images and/or the online field data. Alternatively, determining the treatment product composition may include adjusting the treatment product composition provided via the parameter pack based on the captured images and/or the online field data.

The inclusion of the predetermined parameter package into the treatment device control improves decision making and thus the efficiency of the treatment and/or the efficacy of the treatment product. Thus, an improved method of plant treatment of a field of plants for improving the economic return on investment and improving the impact of the ecosystem is provided.

In a preferred embodiment, the method comprises:

receiving, by a field manager system, offline field data;

determining a parameter package for the treatment device and optionally at least one treatment product composition in dependence on the offline field data; and

providing the determined parameter package and optionally the determined treatment product composition to a treatment device.

Determining the parameter package requires relatively many resources. Processing devices typically have only relatively low computational power, particularly when real-time computational decisions are required during processing. Therefore, the computationally intensive process is preferably done off-line from outside the processing device. Further, the field manager system may be integrated in a cloud computing system. Such systems are almost always on-line and typically have higher computing power than the internal control systems of the processing devices.

Thus, the efficiency of the treatment and/or the efficacy of the treated product may be improved. Thus, an improved method of plant treatment of a field of plants for improving the economic return on investment and improving the impact of the ecosystem is provided.

In one embodiment, the offline field data includes local yield expectation data, resistance data related to the likelihood of plant resistance to treatment products, expected weather data, expected plant growth data, expected weed growth data, regional information data related to different regions of the field of plants, e.g., as determined based on biomass, expected soil data, and/or legal restrictions data.

In a further embodiment, the expected weather data refers to data reflecting forecasted weather conditions. Based on such data, the determination of a parameter package or profile of a treatment arrangement for administration is enhanced, as the efficacy impact on the treatment product may be included in the activation decision and dosage. For example, if high humidity weather exists, a decision can be made to apply the treatment product, as it is very effective in such cases. The expected weather data may be spatially resolved to provide weather conditions in different areas or at different locations in the field of plants where processing decisions are to be made.

In further embodiments, the expected weather data includes various parameters such as temperature, UV intensity, humidity, rainfall forecast, evaporation, dew. Based on such data, the determination of a parameter package or profile of a treatment arrangement for administration is enhanced, as the efficacy impact on the treatment product may be included in the activation decision and dosage. For example, if high temperatures and high UV intensities are present, the dosage of the treatment product may be increased to compensate for faster evaporation. On the other hand, if, for example, the temperature and UV intensity are moderate, the metabolism of the plants is more active and the dose of the treated product can be reduced.

In further embodiments, it is contemplated that soil data, such as soil moisture data, soil nutrient content data, or soil composition data, may be accessed from an external repository. Based on such data, the determination of a parameter package or profile of a treatment arrangement for administration is enhanced, as the efficacy impact on the treatment product may be included in the activation decision and dosage. For example, if high soil moisture is present, decisions may be taken not to apply treatment products due to sweeping effects. It is contemplated that the soil data may be spatially resolved to provide soil moisture characteristics in different regions or at different locations in a field of plants where processing decisions will be made.

In further embodiments, at least a portion of the offline field data includes historical yield maps, historical satellite images, and/or spatially unique crop growth models. In one example, a performance map may be generated based on historical satellite images including, for example, field images for different points in one season of a plurality of seasons. Such a performance map allows for identifying a change in fertility in a field, for example by mapping a number of seasonal more fertile or less fertile areas.

Preferably, the expected plant growth data is determined depending on the amount of water still available in the soil of the plant and/or the expected weather data.

In a preferred embodiment, the legal limits data include leaching risk, in particular infiltration into groundwater; and/or field slopes, particularly to cause surface drainage; and/or require a buffer to the sensitive volume.

Preferably, legal restrictions prohibit the use of specific treatment products under specific conditions in a field of plants. Preferably, the border regions extending around the border of the field of plants are sensitive regions, for example due to their increased exposure to humans and their pets. Thus, effective treatment products that may have an increased negative impact on other organisms may be prohibited in the sensitive area itself and in the buffer area between the sensitive area and the application area of the treatment product.

In a preferred embodiment, the method comprises:

regional information data is determined based on a regional map of an existing field of plants.

Preferably, the region map comprises at least a boundary region, a buffer region and/or a sensitive region.

The region information preferably relates to the region of the region map in which the image is taken and the plant species to be treated is thus located. The area information includes, for example, information that the plant species to be treated is located in the boundary area. The border area is limited by certain legal restrictions regarding the treatment product. If the composition of the treatment product identified for a particular area violates the legal limits of the area of the plant, another treatment product must be identified to treat the plant.

It is therefore possible to treat plants on a field of plants with different types of treatment products, which improves the economic return on investment and the impact of the method on the ecosystem.

In a preferred embodiment, the method comprises:

identifying the object comprises identifying the plant, preferably the type of the plant and/or the size of the plant; insects, preferably insect type and/or insect size; and/or pathogen, preferably pathogen type and/or pathogen size.

In a preferred embodiment, the method comprises:

receiving, by a processing device, online field data relating to current conditions on a field of plants; and

determining a control signal depending on the determined parameter package, the selected treatment product composition and the determined identification object and/or the determined online field data.

Determining online field data by the processing device may include sensors mounted on or placed in the field and received by the processing device.

In a preferred embodiment, the method comprises:

the online field data relates to current weather data, current plant growth data, and/or current soil data, such as soil moisture data.

In one embodiment, the current weather data is recorded in flight or on site. Such current weather data may be generated by different types of weather sensors mounted on the processing device or one or more weather stations placed in or near the field. Thus, current weather data may be measured during movement of the processing device over the field of plants. Current weather data refers to data reflecting weather conditions in a field of plants at a location where a processing decision is to be made. The weather sensor is for example a rain, UV or wind sensor.

In a further embodiment, the current weather data includes various parameters such as temperature, UV intensity, humidity, rainfall forecast, evaporation, dew. Based on such data, the determination of the configuration of the treatment device for administration is enhanced, as the effect on the efficacy of the treatment product may be included in the activation decision and dosage. For example, if high temperatures and high UV intensities are present, the dosage of the treatment product may be increased to compensate for faster evaporation.

In a further embodiment, the online field data includes current soil data. Such data may be provided by soil sensors placed in the field, or it may be accessed from, for example, a repository. In the latter case, the current soil data may be downloaded onto a storage medium of the agricultural machine that includes the treatment gun(s). Based on such data, the determination of the configuration of the treatment arrangement for administration is enhanced, as the efficacy impact on the treatment product may be included in the activation decision and dosage. For example, if high soil moisture is present, a decision may be taken not to apply the treatment product due to sweeping effects.

In further embodiments, current or expected weather data and/or current or expected soil data may be provided to a growth stage model to further determine the growth stage of the plant, weed, or crop plant. Additionally or alternatively, weather data and soil data may be provided to the disease model. Based on such data, the determination of the configuration of the treatment device (in particular the part of the treatment arrangement like a single nozzle) for application is enhanced, as the efficacy impact on the treatment product, such as for example weeds and crops will grow at different rates during this time as well as after application, may be included in the activation decision and dosage. Thus for example the size of the weeds at the time of application or the stage of infection of the pathogen (seen or derived from the infection events in the model) can be included in the activation decision and dose.

In a preferred embodiment, the method comprises the steps of:

determining or providing validation data depending on a performance review of a treatment of the plant; and

adjusting the parameter pack and/or the at least one treatment product composition in dependence on the validation data.

The validation data may be at least partially spatially resolved for the field of plants. The validation data may be measured, for example, in a particular location of a field of plants.

Preferably, the performance audit comprises manual control of the parameter package and/or the at least one treatment product composition and/or automatic control of the parameter package and/or the at least one treatment product composition. For example, manual control involves farmers observing a field of plants and answering questionnaires. In a further example, the performance examination is performed by capturing an image of a portion of a field of plants that has been processed and analyzing the captured image. In other words, performance reviews assess the efficiency of a treatment and/or the efficacy of a treated product after a plant has been treated. For example, if an already treated weed is still present, despite its treatment, a performance audit will include information that the parameter package used for the treatment and/or at least one treatment product composition did not achieve the goal of killing the weed.

In a preferred embodiment, the method comprises:

the parameter package and/or the at least one treatment product composition is adjusted using a machine learning algorithm.

The machine learning algorithms may include decision trees, naive bayes classification, nearest neighbors, neural networks, convolutional or recursive neural networks, generating countermeasure networks, support vector machines, linear regression, logistic regression, random forests, and/or gradient boosting algorithms. Preferably, the results of the machine learning algorithm are used to adjust the parameter package.

Preferably, the machine learning algorithm is organized to process inputs with high dimensionality into outputs with much lower dimensionality. Such a machine learning algorithm is referred to as "intelligent" because it can be "trained". The algorithm may be trained using a record of training data. The training data records include training input data and corresponding training output data. The training output data of a training data record is the result that is expected to be produced by a machine learning algorithm given the training input data of the same training data record as input. The deviation between this expected result and the actual result produced by the algorithm is observed and evaluated by means of a "loss function". The loss function is used as feedback for adjusting parameters of the internal processing chain of the machine learning algorithm. For example, optimization target adjustment parameters that minimize the value of the loss function of the result when all training input data is fed into the machine learning algorithm and the result is compared to the corresponding training output data may be utilized. The result of this training is that a relatively small number of training data records are given as "ground truth," enabling machine learning algorithms to perform their work well for a large number of input data records many orders of magnitude higher.

Detailed Description

Fig. 1 shows a plant processing system 400 for processing plants of a plant field 300 by at least one processing device 200 controlled by a field manager system 100.

The processing device 200, preferably a smart sprayer, comprises a process control unit 210, an image capturing device 220, an image recognition unit 230 and a processing arrangement 270 as well as a parameter pack interface 240 and an online field data interface 250.

The image capture device 220 includes at least one camera configured to capture an image 20 of a field of plants 300. The captured image 20 is provided to the image recognition unit 230 of the processing device 200.

The field manager system 100 includes a machine learning unit 110. In addition, the field manager system 100 includes an offline field data interface 150, a parameter package interface 140, and a validation data interface 160. The field manager system 100 may refer to a data processing element, such as a microprocessor, microcontroller, Field Programmable Gate Array (FPGA), Central Processing Unit (CPU), Digital Signal Processor (DSP), capable of receiving field data, for example, via a Universal Service Bus (USB), physical cable, bluetooth, or another form of data connection. A field manager system 100 may be provided for each processing device 200. Alternatively, the field manager system may be a central field manager system, such as a cloud computing environment or a Personal Computer (PC), for controlling the plurality of processing devices 200 in the field 300.

The field manager system 100 is provided with offline field data Doff related to expected condition data for the plant field 300. Preferably, the off-line field data Doff includes local yield expectation data, resistance data relating to the likelihood of plant resistance to the treatment product, expected weather condition data, expected plant growth data, regional information data relating to different regions of the plant field, expected soil data, such as soil moisture data, and/or legal restrictions data.

Offline field data Doff is provided from an external repository. For example, the expected weather data may be based on satellite data used to predict weather or measured weather data. The expected plant growth data is provided, for example, from a database storing different plant growth stages or from a plant growth stage model that reviews expected growth stages of crops, weeds, and/or pathogens depending on past field condition data. It is contemplated that plant growth data may be provided by a plant model that is essentially a digital twin of the corresponding plant and estimates the growth stage of the plant, particularly depending on prior field data. Further, expected soil moisture data may be determined, for example, depending on past, present, and expected weather condition data. The offline field data Doff may also be provided by an external service provider.

Depending on the offline field data Doff, the machine learning unit 110 determines the parameter package 10. Preferably, the machine learning unit 110 knows the scheduled time for the treatment of the plant. For example, a farmer provides information to the field management system 100 that he plans to treat plants in a particular field the next day. The parameter package 10 is preferably represented as a configuration file provided to the parameter package interface 140 of the field manager system 100. Ideally, the parameter package 10 is determined by the machine learning unit 110 on the same day that the processing device 200 is using the parameter package 10. Here, the machine learning unit 110 may include trained machine learning algorithm(s), wherein the output of the machine learning algorithm(s) may be used for the parameter package. The determination of the parameter package may also be performed without involving any machine learning algorithm. Via the parameter packet interface 140, the parameter packet 10 is provided to the processing device 200, in particular to the parameter packet interface 240 of the processing device 200. For example, the parameter package 10 in the form of a configuration file is transferred and stored in a memory of the processing device 200

Further, the machine learning unit determines at least a treatment product composition 40 intended for treating plants in the field 300. The determination is made in view of the entire plant field 300 or at least a portion of the plant field 300 that is planned for processing. At least one product composition 40 relates to different herbicides, pathogens and/or pesticides and a mixed solution like water or a nutrient solution like nitrogen solution for mixing with the treatment product. For example, the machine learning unit knows from determining the first active ingredient AI1 and the second active ingredient AI2 that both are different herbicides. The treatment product composition 40 is preferably represented as part of a parameter package in a configuration file provided to the parameter package interface 140 of the field manager system 100. Desirably, the treatment product composition 40 is determined by the machine learning unit 110 on the same day that the treatment device 200 is using the treatment product composition 40. Via the parameter pack interface 140, the treatment product composition 40 is provided to the treatment device 200, in particular the parameter pack interface 240 of the treatment device 200. For example, the treatment product composition 40 in the form of a configuration file is updated to the memory of the treatment device 200.

When the parameter pack 10 including the treatment product composition 40 is received by the treatment device 200, in particular the treatment control unit 210, treatment of the plants in the plant field 300 may begin. Ideally, the user, particularly the farmer, additionally provides the barrel formula by the field manager 100. The barrel recipe is determined depending on the parameter package 10 including the determined treatment product composition 40. Thus, the farmer knows approximately how much of the treatment product of which treatment product composition 40 is needed to treat plants in the plant field 300.

The processing device 200 moves around the plant field 300 and detects and identifies objects 30, particularly crops, weeds, pathogens, and/or insects on the plant field 300.

Thus, the image capture device 200 continuously captures images 20 of the field of plants 300. The image 20 is provided to an image recognition unit 230, which image recognition unit 230 performs an image analysis on the image 20 and detects and/or recognizes the object 30 on the image 20. The object 30 to be detected is preferably a crop, weed, pathogen and/or insect. Identifying the object comprises identifying a plant, preferably a plant type and/or a plant size; insects, preferably insect type and/or insect size; and/or pathogen, preferably pathogen type and/or pathogen size. For example, it should be recognized that there is a difference between amaranthus retroflexus and crab, or between bees and locusts, for example. The object 30 is provided to the process control unit 210.

The process control unit 210 is provided with a parameter package 10 comprising, in the form of a profile, the process product composition(s), a first active ingredient AI1 and a second active ingredient AI 2. The parameter package 10 may be shown as a decision tree, where, based on input data, the treatment of the plant and optionally the dosage and composition of the treatment product is decided on different levels of the decision. For example, in a first step it is checked whether the biomass of the detected weeds exceeds a predetermined threshold set by the parameter package 10. The biomass of the weeds is generally related to the extent of weed coverage in the captured image 20. For example, if the biomass of the weeds is below 4%, it is decided not to treat the weeds at all. If the biomass of the weed is above 4%, a further decision is made. For example, in the second step, if the biomass of the weeds is higher than 4%, it is decided whether or not to treat the weeds depending on the soil moisture. If the soil moisture exceeds a predetermined threshold, it is still decided to treat weeds, and otherwise it is decided not to treat weeds. This is because herbicides used to treat weeds may be more effective when the weeds are in a growth phase induced by high soil moisture. The parameter package 10 already comprises information about the expected soil moisture. Since it has been raining for the past few days, it is predicted that the soil moisture is above a predetermined threshold and it will be decided to treat the weeds. However, the process control unit 210 is also provided by the online field data Don, in which case additional data is provided to the process control unit 210 from the soil moisture sensor. Thus, the decision tree for the profile will be decided based on the online field data Don. In an exemplary embodiment, the online field data Don includes information that the soil moisture is below a predetermined threshold. Therefore, it was decided not to treat weeds.

The process control unit 210 generates a process control signal S based on the parameter package 10, the identified object and/or the online field data Don. Thus, the processing control signal S contains information whether the identified object 20 should be processed or not. The process control unit 210 then provides a process control signal S to the processing arrangement 270, which processing arrangement 270 processes the plant based on the control signal S. The treatment arrangement 270 comprises in particular a chemical point spray gun with different nozzles, which makes it possible to spray herbicides, insecticides and/or fungicides with high accuracy.

Thus, the parameter package 10 is provided in dependence on the offline field data Doff relating to the expected field conditions. Based on the parameter package 10, the processing device 200 may decide which kind of plant should be processed based on only the context-identified objects in the field. Thus, the efficiency of the treatment and/or the efficacy of the treated product may be improved. To further improve the efficiency of the treatment and/or the efficacy of the treated product, the online field data Don may be used to include the current measurable conditions of the field of plants.

The provided processing arrangement 400 is additionally capable of learning. The machine learning unit 110 determines the parameter package 10 depending on a given heuristic. After plant treatment based on the provided parameter package 10, it is possible to verify the efficiency of the treatment and the efficacy of the treated product. For example, a farmer may provide field data for a portion of a field of plants that has been previously processed based on the parameter package 10 to the field manager system 100. This information is called authentication data V. The validation data V is provided to the field manager system 100 via the validation data interface 160, providing the validation data V to the machine learning unit 110. The machine learning unit 110 then adjusts the parameter package 10 or a heuristic for determining the parameter package 10 from the validation data V. For example, verification data V indicates that weeds that have been treated based on parameter package 10 are not killed, and parameter package 10 adjusted lowers the threshold to treat plants in one of the branches of the underlying decision tree.

Instead of the parameter package 10 and/or the treatment product composition 40 in the form of a configuration file provided by the external field manager system 100 to the processing device 200, the functionality of the field manager system 100 may also be embedded in the processing device 200. For example, a processing device with relatively high computing power can integrate the field manager system 100 within the processing device 200. Alternatively, all described functions of the field manager system 100 and up to the determination of the control signal S by the processing device 200 may be calculated outside the processing device 200, preferably via a cloud service. Thus, the processing device 200 is simply a "dumb" device for processing the plant species depending on the provided control signal S.

Fig. 2 shows a flow chart of a plant treatment method.

In step S10, a parameter package 10 for controlling the processing device 200 is received by the processing device 200 from the field manager system 100, wherein the parameter package 10 depends on the offline field data Doff relating to expected conditions on the plant field 300, and at least one treatment product composition 40 expected for treating plants is received that depends on the parameter package 10. In step S20, an image 20 of a plant of the plant field 300 is captured. In step S30, the object 30 on the captured image 20 is detected. In step S40, at least one of the at least one treatment product composition 40 is selected for treating the plant, depending on the determined parameter package 10 and the identified object 30. In step S50, a control signal S for controlling the treatment arrangement 270 of the treatment device 200 is determined based on the determined parameter pack 10, the identified object 30 and the selected treatment product composition 40.

Fig. 3 shows a regional map 33 of a field 300 of plants. The zone map 33 divides the plant field 300 into different zones ZB, ZC depending on the type of zone map 33. In this case, the zone map 33 divides the plant field 300 into a center zone ZC and a boundary zone ZB. The boundary region ZB extends around the edge of the plant field 300. The boundary zone ZB is easily accessible to unauthorized persons and is therefore under more stringent legal restrictions than the central zone ZC. Based on the zone map 33, zone information is determined indicating the special legal restrictions of the different zones ZB, ZC.

Fig. 4 shows a processing device 200 in the form of an Unmanned Aerial Vehicle (UAV) flying through a field of plants 300 containing a crop 410. There are also many weeds 421, 422 between crops 410, weeds 421, 422 are particularly toxic, produce many seeds and may significantly affect crop yield. The weeds 421, 422 should not be tolerated in the field of plants 300 containing the crop 410.

UAV200 has an image capture device 220 that includes one or more cameras and captures images as it flies through the plant field 300. UAV200 also has a GPS and inertial navigation system that enables the position of UAV200 to be determined and the orientation of camera 220 to be determined as well. From this information, the footprint of the image on the ground may be determined so that a particular portion of the image, such as an example of a crop, weed, insect, and/or pathogen type, may be located relative to absolute geospatial coordinates. The image data captured by the image capturing device 220 is transferred to the image recognition unit 120.

The image captured by the image capturing device 220 has a resolution that enables one type of crop to be distinguished from another type of crop, and a resolution that enables one type of weed to be distinguished from another type of weed, and a resolution that enables not only detection of insects but also distinguishing of one type of insect from another type of insect, and a resolution that enables one type of pathogen to be distinguished from another type of pathogen.

The image recognition unit 120 may be external to the UAV200, but the UAV200 itself may have the necessary processing capabilities to detect and identify crops, weeds, insects, and/or pathogens. The image recognition unit 120 processes the images using a machine learning algorithm, for example, an artificial neural network based on a number of image examples that have been trained on different types of crops, weeds, insects, and/or pathogens, to determine which object is present and also to determine the type of object.

The UAV also has a treatment arrangement 260, in particular a chemical point spray gun with different nozzles, which enables it to spray herbicides, insecticides and/or fungicides with high precision.

To treat weeds 421, 422, UAV200 can use two different treatment product compositions, a first active ingredient AI1 and a second active ingredient AI 2. For example, the weeds 421, 422 are amaranthus retroflexus and crab grass that are intended to be treated on the field. Both weeds were treated particularly well with the first active ingredient AI 1. The first active ingredient AI1 is less expensive and more effective than the second active ingredient AI2, but is also considered to be more ecologically hazardous. The field manager system 100 provides barrel recipes to farmers. In this case, the field 300 comprises a relatively large central zone ZC and a relatively small border zone ZB, as shown in fig. 3. In view of legal limitations, the first active ingredient AI1 is more legally limited than the second active ingredient AI 2. In this case, this means that in the boundary zone ZB the first active ingredient AI1 is legally not allowed to be used. Thus, the provided bucket formulations indicate that a larger amount of the first active ingredient AI1, which can generally be used in the relatively large central zone ZC, is required than the second active ingredient AI2, which is allowed in the relatively small border zone ZB. The farmer can then equip the treatment apparatus with the corresponding treatment product. A first active ingredient AI1 is stored in first active ingredient bucket 271 and a second active ingredient AI2 is stored in second active ingredient bucket 272. Treatment arrangement 270 is capable of treating plants in a plant field from first active ingredient barrel 271 and/or second active ingredient barrel 272.

As shown in fig. 5, the image capture device 220 captures an image 20 of a field 300. The image recognition analysis detects four objects 30 and identifies two crops 410 (triangles), a first unwanted weed 421 (circles), and a second unwanted weed 422 (circles). Thus, UAV200 is controlled to treat unwanted weeds 421, 422. However, the first weeds 421 are arranged in the central zone ZC of the plant field and the second weeds 422 are arranged in the buffer zone ZB of the plant field. Based on the online field data Don, the captured images 20 and the treatment product composition, it was determined that the weeds 421, 422 were treated with the cheaper and more effective first active ingredient AI 1. However, the first active ingredient AI1 is not allowed to be used in the boundary zone ZB. Thus, the second weeds 422 in the border zone ZB will be identified as being treated by the second active ingredient AI 2. Without determining the different treatment products AI1, AI2, the UAV200 was only able to treat the entire field of plants 300 with the second active ingredient AI2 so as not to violate the specific legal limits of the border area ZB.

Thus, an improved method of plant treatment of a field of plants for improving the economic return on investment and improving the impact of the ecosystem is provided.
