Description

Technical Field

[0001] This application relates to the technical field of intelligent devices, for example, a method and device for refrigerator control, and a refrigerator. Background Art

[0002] With the continuous development of intelligent technology, the functions of refrigerators are becoming more and more powerful, and the user experience is getting better and better. When users are cooking in the kitchen, sometimes it is not convenient to directly operate the refrigerator with greasy hands, so a non-contact operation method is needed to control the refrigerator.

[0003] Currently, there are various ways to control the refrigerator non-contact, such as: through a remote control device, a hand-worn sensing device, or gesture control. However, with the development of precise temperature control technology for refrigerators, the refrigerator may be divided into two or more areas, and each area corresponds to a door body, for example: a refrigerating door body, a freezing door body, and a variable-temperature door body. At present, it is still difficult to accurately locate each door body by current gesture control, and then perform corresponding non-contact control. Summary of the Invention

[0004] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. The summary is not a general review, nor is it intended to identify key / important constituent elements or delineate the protection scope of these embodiments, but rather serves as a preface to the subsequent detailed description.

[0005] Embodiments of the present disclosure provide a method, device, and refrigerator for refrigerator control to solve the technical problem of non-contact control of a refrigerator with at least two doors.

[0006] In some embodiments, the method includes:

[0007] Obtain video information of a user within a set range of the refrigerator;

[0008] Perform image recognition on the video information to determine the current gesture information and body area information of the user;

[0009] Determine a door to be controlled on the refrigerator that matches the gesture action area according to the current gesture information and the body area information;

[0010] Control the operation of the door to be controlled according to the current gesture information.

[0011] In some embodiments, the device includes:

[0013] An identification and determination module, configured to perform image recognition on the video information to determine the current gesture information and body area information of the user;

[0014] A door body determination module, configured to determine the door to be controlled on the refrigerator that matches the gesture action area according to the current gesture information and the body area information;

[0015] A control module, configured to control the operation of the door to be controlled according to the current gesture information.

[0016] In some embodiments, the device for refrigerator control includes a processor and a memory storing program instructions. The processor is configured to execute the above-mentioned method for refrigerator control when executing the program instructions.

[0017] In some embodiments, the refrigerator includes the above-mentioned device for refrigerator control.

[0018] The method, device and refrigerator for refrigerator control provided by the embodiments of the present disclosure can achieve the following technical effects:

[0019] Through image recognition, not only can the gesture information of the refrigerator user be determined, but also the gesture action area of the gesture relative to the user's body can be determined. In this way, according to the gesture information, the door on the refrigerator that matches the gesture action area can be controlled to run independently. Thus, not only can non-contact control of the refrigerator be achieved, but also each door body in the refrigerator can be accurately positioned, and then different door bodies on the refrigerator can be controlled separately, further improving the convenience and intelligence of refrigerator control and also improving the user experience.

It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of the present disclosure described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0030] Unless otherwise specified, the term "plurality" means two or more.

[0031] In the embodiments of the present disclosure, the character " / " indicates that the objects before and after are in an "or" relationship. For example, A / B means: A or B.

[0032] The term "and / or" is an associative relationship describing objects and indicates that three relationships can exist. For example, A and / or B means: A or B, or, A and B these three relationships.

[0033] In the embodiments of the present disclosure, there are two or more doors in the refrigerator. According to different gestures of the refrigerator user, different movements of the doors can be controlled, such as: opening or closing. Moreover, the individual movement of each door body can also be controlled by gestures, further improving the convenience and intelligence of refrigerator control and also improving the user experience.

[0034] Figure 1 It is a schematic flowchart of a refrigerator control method provided by an embodiment of the present disclosure. As Figure 1 shown, the process for refrigerator control includes:

[0035] Step 101: Obtain the video information of users within the set range of the refrigerator.

[0036] Currently, an image acquisition device can be configured on the refrigerator to collect the video information of users within the set range. For example, the video information of users within the set range of the refrigerator can be obtained through a camera embedded in the refrigerator panel.

[0037] The image acquisition device can collect the video information of users in real time or be activated only after meeting the set conditions. Therefore, in some embodiments, when the human body sensor configured on the refrigerator determines that there is a user within the set range of the refrigerator, the image acquisition device is activated to obtain the corresponding video information of the user. Among them, the human body sensor can include: an infrared sensor, a photoelectric sensor, etc., and will not be listed one by one here.

[0038] Step 102: Perform image recognition on the video information to determine the current gesture information and body area information of the user.

[0039] Performing image recognition on each frame of the obtained video information can not only determine the hand position information of the hand in each frame of the image, but also determine the position information of other parts of the body, such as: head position information, shoulder position information, waist position information, and leg position information, etc., one, two or more of these information. Then, according to the hand position information in each frame of the image, the hand movement estimation information, that is, the current gesture information, can be obtained. Then, according to the position information of the body parts in each frame of the image, the body area information can be determined, which can include: the position information of each feature point, such as: the highest position information, the lowest position information, the leftmost position information, and the rightmost position information, etc.; or, the position information at the top of the head, the boundary position information at the fingertips, the knee joint position information, etc.

[0040] Existing image recognition processes can all be applied to this step and will not be listed one by one here.

[0041] Step 103: Determine the door to be controlled on the refrigerator that matches the gesture action area according to the current gesture information and the body area information.

[0042] After obtaining the current gesture information and the body area information, the action area of the gesture relative to the body can be determined. For example: the hand moves within the upper half range of the body, that is, the action area of the gesture relative to the body is the upper body area, or the action area of the gesture relative to the body is the lower body area. Of course, this embodiment is not limited to this. Different area divisions of the body can determine different gesture action areas. For example: it can be divided into two areas, three areas, four areas, six areas, etc.

[0043] The body area can be divided according to the model of the refrigerator. Further, the body area can be divided according to the door body of the refrigerator. Therefore, in the embodiments of the present disclosure, the correspondence between the body area and the refrigerator door can also be configured and saved. The body area can specifically be rectangular, square or circular. In some embodiments, the first correspondence between the rectangular body area and the refrigerator door can be saved.

[0044] Figure 2 It is a schematic diagram of a rectangular body area and a refrigerator door in the embodiments of the present disclosure. As Figure 2 shown, the human body can be divided into six body areas, namely: the upper left rectangular body area ①, the upper right rectangular body area ②, the left middle rectangular body area ③, the right middle rectangular body area ④, the lower left rectangular body area ⑤, and the lower right rectangular body area ⑥. And there are four doors on the refrigerator, namely the upper left refrigerating door ①, the upper right refrigerating door ②, the variable temperature control door ③, and the freezing door ④.

[0045] Table 1 is the first correspondence between the rectangular body area and the refrigerator door in the embodiments of the present disclosure.

[0046]

[0047] Table 1

[0048] After saving the first correspondence between the rectangular body area and the refrigerator door, determining the door to be controlled on the refrigerator that matches the gesture action area can include: forming at least two rectangular body areas according to the body area information; determining the current rectangular body area of the gesture relative to the body in the current gesture information; and determining the door to be controlled that matches the current rectangular body area according to the saved first correspondence.

[0049] For example: if the correspondence shown in Table 1 is saved, six rectangular body areas can be formed according to the body area information, which can include forming six rectangular body areas as Figure 2 shown according to the feature point position information such as the position information at the top of the head, the boundary position information at the fingertips, and the knee joint position information in the body area information. Then, count the position information of the hand in the current gesture information, and determine the current rectangular body area of the gesture relative to the body as the rectangular body area where the hand position information appears most frequently. Finally, determine the door to be controlled that matches the current rectangular body area according to the first correspondence in Table 1. Among them, if the current rectangular body area is the left middle rectangular body area ③, the variable temperature control door ③ is the door to be controlled; if the current rectangular body area is the lower left rectangular body area ⑤, the freezing door ④ is the door to be controlled.

[0050] Step 104: Control the operation of the door to be controlled according to the current gesture information.

[0051] In the embodiments of the present disclosure, a second correspondence between gesture information and door control instructions can be saved. In this way, after determining the door to be controlled, the current door control instruction matching the current gesture information can be determined according to the second correspondence; and the current door control instruction is sent to the driving device corresponding to the door to be controlled to drive the door to be controlled.

[0052] Table 2 shows a first correspondence between gesture information and door control instructions in the embodiments of the present disclosure.

[0053] Gesture information Door control instruction Wave from top to bottom, or, palm open, or,... Opening instruction Wave from bottom to top, or, palm closed, or,... Closing instruction … …

[0054] Table 2

[0055] As shown in Table 2, if the gesture information is a wave from top to bottom, it can be determined that the opening instruction is the current door control instruction; and if the gesture information is the palms closing together, it can be determined that the closing instruction is the current door control instruction. Of course, the embodiments of the present disclosure are not limited to this, and will not be enumerated one by one.

[0056] The movement of the door body is specifically controlled by the corresponding driving device, that is, after determining the current door control instruction according to the second correspondence, the current door control instruction can be sent to the driving device corresponding to the door to be controlled to drive the door to be controlled.

[0057] It can be seen that in this embodiment, through image recognition, not only the gesture information of the refrigerator user can be determined, but also the gesture action area of the gesture relative to the user's body can be determined. In this way, according to the gesture information, the door on the refrigerator matching the gesture action area can be controlled to run independently. Thus, not only the non-contact control of the refrigerator can be realized, but also different door bodies on the refrigerator can be separately controlled, further improving the convenience and intelligence of refrigerator control, and also improving the user experience.

[0058] Of course, in this embodiment, a second correspondence can be configured for the entire refrigerator, or different second correspondences can be configured for each door body of the refrigerator. In this way, different gestures can control different movements of different doors, further improving the flexibility of gesture control of the refrigerator.

[0059] Next, the operation process will be incorporated into specific embodiments to illustrate the refrigerator control process provided by the embodiments of the present invention.

[0060] In an embodiment of the present disclosure, there are four doors in the refrigerator as Figure 2 shown, and a camera and an infrared human body sensor are embedded in the panel, and the corresponding relationships shown in Table 1 and Table 2 are saved.

[0061] Figure 3 is a schematic flow chart of a method for refrigerator control provided by the embodiments of the present disclosure. Combining Figure 3 , the process for refrigerator control includes:

[0062] Step 301: Determine whether there is a user within the set range of the refrigerator through an infrared human sensor. If so, execute Step 302; otherwise, return to Step 308.

[0063] Step 302: Activate the camera to obtain the video information of the user.

[0064] Step 303: Perform image recognition on each frame of the video information to determine the current gesture information and body area information of the user.

[0065] Step 304: According to the body area information, form six body rectangular areas and determine the current body rectangular area of the gesture relative to the body in the current gesture information.

[0066] Step 305: According to the first correspondence relationship between the saved body rectangular area and the refrigerator door, determine the door to be controlled that matches the current rectangular body area.

[0067] Step 306: According to the second correspondence relationship between the saved gesture information and the door control instruction, determine the current door control instruction that matches the current gesture information.

[0068] Step 307: Send the current door control instruction to the drive device corresponding to the door to be controlled to drive the door to be controlled.

[0069] Step 308: Keep the camera in the off state.

[0070] In this embodiment, for example, when the user's hand waves from top to bottom in the upper right of the body, according to the first correspondence relationship in Table 1, the upper right refrigerating door ② can be determined as the door to be controlled. According to the second correspondence relationship in Table 2, the opening instruction can be determined as the current door control instruction. Thus, the upper right refrigerating door on the refrigerator can be controlled to open.

[0071] It can be seen that in this embodiment, there are six doors in the refrigerator. According to different gestures of the user in different areas, the individual movement of each door can be controlled, improving the convenience and intelligence of refrigerator control and also enhancing the user experience.

[0072] According to the above process for refrigerator control, a device for refrigerator control can be constructed.

[0073] Figure 4 It is a schematic structural diagram of a device for refrigerator control provided by an embodiment of the present disclosure. As Figure 4 shown, the device for refrigerator control includes: a video acquisition module 410, an identification and determination module 420, a door body determination module 430, and a control module 440.

[0074] The video acquisition module 410 is configured to acquire the video information of the user located within the set range of the refrigerator.

[0075] An identification and determination module 420, configured to perform image recognition on video information to determine the current gesture information and body area information of the user.

[0076] A door body determination module 430, configured to determine the door to be controlled on the refrigerator that matches the gesture action area according to the current gesture information and body area information.

[0077] A control module 440, configured to control the operation of the door to be controlled according to the current gesture information.

[0078] In some embodiments, the device further includes: a configuration saving module, configured to save a first correspondence between the body rectangular area and the refrigerator door, and save a second correspondence between the gesture information and the door control instruction.

[0079] In some embodiments, the door body determination module 430 is specifically configured to form at least two body rectangular areas according to the body area information; determine the current body rectangular area of the gesture relative to the body in the current gesture information; and determine the door to be controlled that matches the current rectangular body area according to the saved first correspondence.

[0080] In some embodiments, the control module 440 is specifically configured to determine the current door control instruction that matches the current gesture information according to the second correspondence; and send the current door control instruction to the driving device corresponding to the door to be controlled to drive the door to be controlled.

[0081] The following is an example to illustrate the refrigerator control process using the refrigerator control device provided by the embodiments of the present disclosure.

[0082] Figure 5 It is a schematic structural diagram of a refrigerator control device provided by the embodiments of the present disclosure. As Figure 5 shown, the refrigerator control device includes: a video acquisition module 410, an identification and determination module 420, a door body determination module 430, a control module 440, and a configuration saving module 450.

[0083] Among them, the refrigerator may include two or more doors. Thus, the configuration saving module 450 can save a first correspondence between the body rectangular area and the refrigerator door according to the refrigerator door body information. Of course, it can also save a second correspondence between the gesture information and the door control instruction.

[0084] In this way, the video acquisition unit 410 can obtain the video information of the user within the set range of the refrigerator in real time. Thus, the recognition and determination module 420 can perform image recognition on each frame of the video information to determine the current gesture information and body area information of the user. Therefore, the door determination module 430 first forms six body rectangular areas based on the body area information and determines the current body rectangular area of the gesture relative to the body in the current gesture information. Then, according to the first correspondence relationship between the body rectangular area saved by the configuration storage module 450 and the refrigerator door, it determines the door to be controlled that matches the current rectangular body area. Therefore, the control module 440 can first determine the current door control instruction that matches the current gesture information according to the second correspondence relationship between the gesture information saved by the configuration storage module 450 and the door control instruction, and then send the current door control instruction to the drive device corresponding to the door to be controlled to drive the door to be controlled.

[0085] It can be seen that in this embodiment, the refrigerator control device can, through image recognition, not only determine the gesture information of the refrigerator user, but also determine the gesture action area of the gesture relative to the user's body. In this way, according to the gesture information, the door on the refrigerator that matches the gesture action area can be controlled to operate independently. Thus, not only can non-contact control of the refrigerator be realized, but also different doors on the refrigerator can be controlled separately, further improving the convenience and intelligence of refrigerator control and also enhancing the user experience.
