Referring to fig. 3, fig. 3 is a schematic flow chart of a display control method of a water dispenser according to an embodiment of the present application.

As shown in fig. 3, the display control method of the water dispenser specifically includes: step S201 to step S205.

S201, obtaining a container image of a container placed below a water outlet of the water dispenser.

The type of the container can be various, for example, the container is a water cup such as a plastic cup, a ceramic cup, a glass cup or a vacuum cup.

In a specific implementation process, a camera can be preset around the water outlet of the water dispenser and used for collecting container images below the water outlet of the water dispenser, wherein the camera can be an infrared camera or other types of cameras, the specific position of the camera can be flexibly set according to actual needs, for example, the camera can be installed obliquely above the water outlet or close to the position of the water outlet, and the like, so that the camera can accurately collect container images below the water outlet of the water dispenser.

S202, controlling the water outlet of the water dispenser according to the container image, and acquiring water quantity change information in the container.

Specifically, after the image of the container placed below the water outlet of the water dispenser is obtained, it is shown that at this time, the container is placed below the water outlet of the water dispenser, so that the water outlet of the water dispenser can be controlled, and the water volume change information in the container can be obtained.

And in the water outlet process of the water dispenser, the water quantity change information in the container is acquired in real time so as to be conveniently presented to a user in real time.

In some embodiments, referring to fig. 4, the step of obtaining the water amount variation information in the container includes step S202a and step S202 b.

S202, 202a, extracting a water surface boundary generated based on the tension formed between the container and the water from the container image.

The water in the container can form an adhesion effect on the inner wall of the container due to the existence of tension, so that the water optically shows optical characteristics such as abnormal refraction effect, and the optical characteristics can be captured and identified through a camera in the view of visual identification technology. Therefore, as shown in fig. 5, in the process of water outlet of the water dispenser, after a container image containing the container is acquired, a water surface boundary generated based on tension formed between the container and water can be extracted from the container image. In the process of water outlet of the instant water dispenser, the water surface in the container fluctuates due to tension, and the boundary of the inner wall of the container is provided with an obvious reflective boundary, so that the boundary of the water surface can be obtained through image analysis. For example, the last frame of container image in the multi-frame container images is compared with the previous N frames (the specific value of N is flexibly set according to actual needs), so as to obtain an area with obvious brightness difference, which is the area of the current water surface, i.e. the water surface boundary.

In addition, in order to improve the accuracy of acquiring the water surface boundary, filtering or smoothing and other operations can be performed on the extracted water surface boundary, so that noise points, cavity points and the like are filtered, and a smooth water surface boundary is obtained.

S202b, determining the water volume percentage in the container according to the corresponding relation between the water surface boundary and the water level value.

Specifically, the water level value refers to the ratio of the amount of water in the vessel to the total volume of the vessel. After the water surface boundary is obtained, the water volume percentage in the container can be determined according to the corresponding relation between the water surface boundary and the water level value. The lower the water level is because the less the water quantity in the container is, the smaller the water surface boundary extracted from the container image is; the more the water quantity in the container is, the higher the water level is, the larger the water surface boundary extracted from the container image is, so that the water quantity percentage in the container can be determined according to the corresponding relation between the size of the extracted water surface boundary and the water level value. Wherein, the corresponding relation between the size of the water surface boundary and the water level value is preset.

In some embodiments, referring to fig. 6, the step of obtaining the water amount variation information in the container includes step S202c and step S202 d.

S202c, determining the volume of the container according to the container image.

Specifically, the water dispenser can be further provided with a structured light camera, so that a structured light stripe image is obtained. Because the three-dimensional information of the object, including three-dimensional geometric information, gray information, color information and the like, is stored in the structured light stripe image, the complete three-dimensional characteristics of the shot container can be reconstructed and restored based on the structured light stripe image, and the reconstruction of the three-dimensional model is carried out. In the specific implementation process, the reconstruction of the three-dimensional model of the container can be performed by adopting a three-dimensional imaging method based on Fourier fringe analysis, a three-dimensional imaging method based on phase shift fringe analysis, three-dimensional imaging of a dynamic process and other methods.

After the reconstruction of the three-dimensional model of the container is completed, the volume of the container is calculated based on the reconstructed three-dimensional model. In the specific implementation process, the volume of the container can be calculated by adopting various methods such as a C + + slicing method, Python or other software commands.

S202d, obtaining water quantity information in the container, and calculating the percentage of the water quantity in the container based on the water quantity information and the volume.

Specifically, the water quantity information in the container can be obtained through a flow meter arranged on the water dispenser, and can also be obtained through a weight sensor arranged on the water dispenser. For example, when the water is obtained through a flow meter arranged on the water dispenser, the current water flow is 10ml/s displayed on the flow meter from the beginning of water outlet of the water dispenser, after the water is continuously discharged for 30s, the water amount information in the container can be calculated to be 300ml, and if the volume of the container is 500ml, the water amount percentage in the container at the moment can be calculated to be 60%. When the water is obtained by the weight sensor, the reading of the weight sensor is gradually increased from the beginning of the water outlet of the water dispenser, and when the reading of the weight sensor is increased by 300g, the density of the clear water is 1g/cm³Therefore, the amount of water in the container at this time is 300ml, and if the volume of the container is 500ml, the percentage of the amount of water in the container at this time can be calculated to be 60%.

And S203, generating a real-time water volume image according to the water volume change information, and displaying the real-time water volume image on the display screen.

Specifically, after the water quantity change information in the container in the water adding process is acquired, a real-time water quantity image is generated according to the water quantity change information, and the real-time water quantity image is displayed on the display screen so that a user can check the water quantity change condition in the container.

In some embodiments, the water amount change information includes a percentage of the water amount in the container, and referring to fig. 7, a real-time water amount image is generated according to the water amount change information, specifically including step S2031 and step S2032.

S2031, obtaining the schematic diagram of the container.

In particular, the schematic of the container may be pre-configured for storage within a drinking machine, for example, the schematic of the container may be as shown in FIG. 8. When the real-time water volume image is presented to the user through the display screen, the acquired schematic diagram of the container may be used as a base image for display, and the real-time change of the water volume in the container is presented to the user in the base image.

S2032, displaying the water volume change of the container in real time in the schematic diagram according to the water volume percentage in the container to obtain a real-time water volume image.

Specifically, the water volume change information comprises the water volume percentage in the container, the water volume percentage in the schematic diagram is modified in real time according to the water volume percentage in the container, and the water volume change in the container is presented in the schematic diagram in real time according to the water volume percentage, so that a real-time water volume image is obtained. For example, where the percentage of water in the container is 20%, the percentage of water in the schematic is also 20%.

And S204, judging whether the water quantity in the container reaches a water level threshold value according to the water quantity change information.

The water level threshold may be a percentage of the water in the container, for example, when the water in the container reaches 80%, the water dispenser stops discharging water, and the water level threshold is 80%. The water level threshold value can also be the size of the water surface boundary, when the water level threshold value is the same as the size of the water surface boundary, the water quantity in the container is larger at the moment, namely the distance of the water level close to the container port at the moment, and the water dispenser is controlled to stop water outlet. Therefore, whether the water amount in the container reaches the water level threshold value can be judged according to the water amount change information in the container.

In some embodiments, the user may adjust the water level threshold by sliding a finger on the schematic diagram of the container from bottom to top, and the height at which the finger of the user finally stays is used as the water level threshold, and the user may also adjust the water level threshold by touching or pressing a button on the display screen, for example, the water level threshold is adjusted to 76%. Similarly, the user can also adjust the water outlet temperature of the water dispenser in the same manner, which is not described herein again.

In some embodiments, the method further comprises: performing contour extraction on the container image to determine a diameter size of an opening contour of the container; determining a diameter interval in which the diameter is positioned to obtain a target diameter interval; and determining the water level threshold corresponding to the target diameter interval according to the mapping relation between the different diameter intervals and the different water level thresholds.

When the container image is subjected to contour extraction, the trained recognition model can be specifically used for carrying out opening contour recognition on the container image, so that the opening contour of the container is obtained. The type of the recognition model can be flexibly set according to actual needs, the recognition model can be a target detection model SSD or YOLOv3, and the recognition model can also be a convolutional neural network CNN or R-CNN. The recognition model can be trained through a plurality of sample images containing the opening outlines of containers of different types, and the trained recognition model is obtained.

After the opening contour of the container is obtained, the preset mapping relation between different diameter intervals and different water level thresholds can be obtained, the diameter size of the opening contour of the container is obtained, and then the diameter interval where the diameter size is located is determined, so that the target diameter interval is obtained. At this time, the water level threshold corresponding to the target diameter section may be determined according to the mapping relationship between the different diameter sections and the different water level thresholds.

S205, when the water amount in the container reaches a water level threshold value, controlling the water dispenser to stop discharging water.

Specifically, if the water amount in the container reaches the water level threshold, it indicates that the water amount in the container is large at this time, that is, the water level is close to the distance of the container port, and at this time, the water dispenser may be controlled to stop discharging water. The automatic control water dispenser not only can automatically control the water outlet and the water cut-off of the water dispenser, but also can reduce the accidents of water resource waste, hot water scald and the like caused by water overflow, and improve the use safety.

According to the water dispenser display control method provided by the embodiment, the container image of the container placed below the water outlet of the water dispenser is obtained, the water outlet of the water dispenser is controlled according to the container image, so that the water quantity change information in the container is obtained, then the real-time water quantity image is generated according to the water quantity change information, and the real-time water quantity image is displayed on the display screen. The real-time water volume image is generated by the water volume change information in the container and visually displayed on the display screen for the user to visually observe the water volume change in the container, the convenience degree of the user is improved, whether the water volume in the container reaches a water level threshold value is judged according to the water volume change information, if the water level threshold value is reached, the water dispenser is controlled to stop water outlet, water outlet and water stop of the water dispenser can be automatically controlled, the use convenience of the user is improved, accidents such as water resource waste and hot water scald caused by water overflow can be reduced, and the use safety is improved.
