The cooking apparatus control method based on user identification described in fig. 1 is applied to a control chip, a control terminal, or a control server (where the control server may be a local server or a cloud server) of a cooking apparatus. As shown in fig. 1, the cooking appliance control method based on user identification may include the operations of:

101. detecting whether the target cooking area has an active entity.

In the embodiment of the present invention, the target cooking area is provided with the target cooking device, and optionally, the target cooking area may be a cooking area of a kitchen or an open kitchen in a home area, or may be a preset fixed area, which does not strictly refer to an area where a regular cooking action is performed, or may be any area where a cooking operation may be performed. Optionally, the target cooking device may be a cooking auxiliary heating device such as a gas stove, an induction cooker, a microwave oven or an oven, or may be an automatic cooking device such as a cooking robot or an electric cooker, and the invention is not limited thereto.

In the embodiment of the present invention, the active entity is used to refer to any physical entity in an active state, which may be an animal or a human being, and the present invention is not limited thereto, and only refers to the active physical entity in the target cooking area, which may be an authorized user. Alternatively, the detection of the active entity may be performed in various ways, and in particular, with reference to various embodiments described below.

102. And when the existence of the movable entity in the target cooking area is detected, judging whether the movable entity is an authorized user.

In an embodiment of the present invention, the authorized user is an authorized human user in a preset database, which may be a designated user of the target cooking device or a member of a family who often uses a kitchen. Optionally, all authorized users may be screened according to the type of the target cooking device to obtain the targeted authorized users for judgment, for example, when the target cooking device is a high-risk cooking facility, an authorized user with an age below a certain threshold will not be screened as the targeted authorized user.

103. And when the movable entity is judged to be the authorized user, unlocking the target cooking equipment.

In an embodiment of the present invention, the target cooking apparatus may include one or more cooking apparatuses. When the target cooking device comprises a plurality of cooking devices, the type of the cooking device included in the target cooking device can be determined according to the identity of the authorized user, and further, the current cooking scene can be determined according to the identity of the authorized user, so that the plurality of cooking devices corresponding to the cooking scene can be determined to be unlocked.

Optionally, the target cooking device may be unlocked, so that the target cooking device is switched from the non-starting state to the starting state for an authorized user to start, or the target cooking device is switched from the non-starting state to the default starting state, for example, the refrigeration device is switched to the preset refrigeration mode.

Therefore, the embodiment of the invention can automatically detect the movable entity in the cooking area and further unlock the cooking equipment when the movable entity is judged to be the authorized user, so that the cooking equipment can be automatically and intelligently unlocked according to the information in the area, the operation complexity of the equipment which is inconvenient for the user to unlock the equipment manually is reduced, and the intelligent degree of the cooking equipment is further improved.

As an alternative embodiment, the step 101 of detecting whether the active entity exists in the target cooking area includes:

acquiring sensing information of a target cooking area;

and detecting whether the movable entity exists in the target cooking area or not according to the sensing information.

In the embodiment of the present invention, the sensing information includes one or more of electromagnetic wave sensing information, image information, video information, and sound information. In particular, such information in the sensory information may be used to indicate status in an entity in the target cooking zone.

Therefore, according to the optional implementation mode, whether a movable entity exists in the target cooking area or not can be detected according to the sensing information of the target cooking area, so that the detection result is more accurate, the subsequent judgment of the accurate unlocking operation is facilitated, and the automatic and intelligent unlocking of the cooking equipment according to the information in the area can be realized.

As an optional implementation manner, in the above steps, detecting whether there is an active entity in the target cooking area according to the sensing information includes:

judging whether movable three-dimensional entity information exists in the three-dimensional model information of the target cooking area;

and when the three-dimensional entity information of the activity is judged to exist, determining that the activity entity exists in the target cooking area.

Optionally, the manner of determining the three-dimensional model information of the target cooking area may be to perform three-dimensional reconstruction on the target cooking area based on a three-dimensional reconstruction algorithm through image information or image information in a video to obtain the three-dimensional model information of the target cooking area, for example, an existing three-dimensional reconstruction algorithm may be used to perform three-dimensional reconstruction operations such as feature point matching and three-dimensional reconstruction on a plurality of pieces of image information according to image feature information, and finally form three-dimensional model data of the target cooking area. Optionally, the three-dimensional reconstruction algorithm may adopt SfM, remodel, SVO, and other algorithms, and such algorithms may be applicable to a plurality of image data acquired by a single image capturing device. Optionally, the three-dimensional reconstruction algorithm may adopt algorithms such as SGM and SGBM, and such algorithms may be applicable to a plurality of image data acquired by the binocular vision/multi-view vision camera device.

Optionally, the mode of determining the three-dimensional model information of the target cooking area may also be that the three-dimensional model information of the target cooking area is obtained by performing three-dimensional reconstruction on the basis of a three-dimensional reconstruction algorithm through electromagnetic wave sensing information, for example, an active three-dimensional reconstruction mode may be selected, for example, a structured light method may be used to determine the three-dimensional model data, and the encoded structured light is projected onto a shot object in the target cooking area by using a projector and then shot by using a camera. The size and shape of the structured light encoded pattern may also change due to the different distance accuracy and direction of different parts on the object being photographed relative to the camera. And then scene characteristic information such as depth information of the cooking area is obtained through the operation unit, and finally three-dimensional model information of the target cooking area is obtained. For another example, a TOF laser time-of-flight method may be used to perform a three-dimensional reconstruction operation, where light pulses are continuously emitted to an object to be photographed in a target cooking area, and the time and phase difference of the return light are determined to determine the distance to the object, so as to obtain scene characteristic information such as depth information, and finally obtain three-dimensional model information of the target cooking area.

Optionally, whether the three-dimensional model information of the target cooking area has the movable three-dimensional entity information is judged, the three-dimensional model information of the target cooking area in two time periods can be compared to determine whether the three-dimensional model information of the area has new three-dimensional entity information or three-dimensional entity information with parameter change meeting a preset parameter change condition, and if the three-dimensional model information of the target cooking area has the movable three-dimensional entity information, the three-dimensional model information of the target cooking area is judged to have the movable three-dimensional entity information. Optionally, the preset parameter change condition may be used to refer to a degree of posture change, position change, or height change of the three-dimensional entity, and is greater than a corresponding degree threshold, for example, a distance of the position change is greater than a corresponding distance threshold.

Therefore, through the optional implementation mode, the three-dimensional model information of the target cooking area can be determined, and whether the movable three-dimensional entity information exists in the three-dimensional model information of the target cooking area is judged, so that whether the movable entity exists in the target cooking area is determined, the detection result is more accurate, the subsequent judgment unlocking operation is facilitated to be accurately carried out, and the cooking equipment can be automatically and intelligently unlocked according to the information in the area.

As an optional implementation manner, in the above steps, detecting whether there is an active entity in the target cooking area according to the sensing information includes:

judging whether a new entity image exists in the image information and/or the video information in the sensing information;

and when judging that the new entity image exists, determining that the target cooking area has the active entity.

Optionally, an image comparison algorithm may be directly used to compare image information of two time periods or time nodes of the target cooking area or image information in the video information to determine whether a new image portion exists, for example, a similarity between the image information of the two time periods or time nodes or the image information in the video information may be calculated first, when the similarity is greater than a preset similarity threshold, a prompt may be made to prompt that a new entity image may exist, then the second step of image comparison is performed, a different difference image portion between the two image information is calculated by using the image comparison algorithm, and when the size of the difference image portion is greater than a preset entity size threshold, it is determined that the new entity image exists in the image information and/or the video information in the sensing information.

Therefore, according to the optional implementation mode, whether a movable entity exists in the target cooking area can be determined by judging whether new entity images exist in the image information and/or the video information in the sensing information, so that the detection result is more accurate, the subsequent judgment of the accurate unlocking operation is facilitated, and the automatic and intelligent unlocking of the cooking equipment according to the information in the area can be realized.

judging whether entity sound information exists in the target cooking area or not according to sound information in the sensing information and a preset sound threshold and/or a sound template;

and when the entity sound information is judged to exist, determining that the target cooking area has the active entity.

In the embodiment of the present invention, the sound threshold may be a sound decibel value that the entity sound should reach, and may be a preset value determined through experiments or based on experience, or may be a value obtained by calculating an average value of minimum values of sound information in the historical entity activity data. The method aims to screen out interference sound in the environment so as to avoid false start.

In the embodiment of the present invention, the sound template is voiceprint information to which the entity sound should follow, is used to indicate voiceprint characteristics in different entity sound information, and can be obtained by performing an operation on historical sound data corresponding to a plurality of entity sounds based on a sound characteristic extraction algorithm model.

Optionally, when it is determined that the decibel value of the sound information is greater than the preset sound threshold or the characteristic of the sound information meets the characteristic condition in the preset sound template, it may be determined that the entity sound information exists in the target cooking area, and it may be further determined that the active entity exists in the target cooking area.

Therefore, according to the optional implementation mode, whether the entity sound information exists in the target cooking area or not can be judged, so that whether the movable entity exists in the target cooking area or not can be determined, the detection result is more accurate, the subsequent judgment of the accurate unlocking operation is facilitated, and the automatic and intelligent unlocking of the cooking equipment according to the information in the area can be realized.

Optionally, when the matching similarity between the user three-dimensional templates of multiple authorized users and the three-dimensional entity information is greater than a preset matching similarity threshold, the authorized user with the maximum matching similarity may be determined as the authorized user corresponding to the active entity.

Therefore, according to the optional implementation mode, whether the movable entity is the authorized user or not can be judged according to the three-dimensional entity information corresponding to the movable entity and the user three-dimensional template corresponding to the authorized user, so that the judgment result is more accurate, the subsequent unlocking operation is facilitated to be accurately carried out, and the cooking equipment can be automatically and intelligently unlocked according to the information in the region.

As an optional implementation manner, the determining whether the active entity is an authorized user in step 102 includes:

The scheme is provided because along with the development of the touch integrated cooker technology and various sensors, the intelligentization of integrated cooker products becomes a trend. However, in a dark scene, for example, at night, when a user enters a dark kitchen, what is needed is to turn on a kitchen lamp and then operate a required kitchen appliance, and the existing scene has 3 disadvantages:

1) the user needs to touch the black to turn on the lighting lamp of the kitchen;

2) when a user needs to use the touch integrated cooker, the user also needs to unlock the touch integrated cooker by pressing for a long time, which wastes time;

3) unauthorized users, such as mice, cats and dogs, children and the like enter a kitchen, and the potential safety hazard of fire caused by the fact that ignition of the integrated cooker is triggered by mistake exists.

In order to solve the above disadvantages, the present invention provides an automatic identification user authorization unlocking method for a touch integrated oven, which can be implemented by adding a user identification system and linkage illumination on the touch integrated oven, specifically, the user identification system detects a user through a body sensor after the user enters (a body detection area of) a kitchen, and determines whether the user is an authorized user, and unlocks the integrated oven immediately if the user is an authorized user, and enters a power-on state, and simultaneously turns on auxiliary illumination of the integrated oven, thereby preventing the user from blindly turning on a kitchen lamp, and if the user is an unauthorized user, the user can be added as an authorized user by using an administrator account.

Adopt user identification system automated inspection user in this scheme, the automatic identification user, when recognition device discerns the authorized user, through built-in control program, will integrate kitchen automatic unlocking start, open auxiliary lighting simultaneously, solved the trouble of the user black-touch turn-on lamp and the unnecessary action of manual unblock, liberated both hands.
