[0043] Figure 1 A flowchart of a control method of a vehicle-mounted refrigerator provided in an embodiment of the application is shown.

[0044] Figure 2 A structural diagram of an electronic device provided in an embodiment of the application is shown. DETAILED DESCRIPTION

[0045] The specific embodiments of the application will be described in more detail below with reference to the accompanying drawings. The advantages and features of the application will be more apparent according to the following description. It should be noted that the drawings are very simplified and use non-precise proportions, only to facilitate and clarify the purpose of assisting the description of the embodiments of the application.

[0046] As described in the background, in the prior art, at present, the vehicle-mounted refrigerator is basically controlled by a fixed switch to start and stop the operation of the refrigerator. Generally, the refrigerator will start to run as soon as the vehicle is powered on, which will cause waste of energy if there is no article in the refrigerator. Especially with the popularization of green new energy vehicles, the air conditioner of the vehicle consumes a lot of energy in summer, so it is very important to save the operation of other vehicle-mounted devices.

[0047] Therefore, in the prior art, the vehicle-mounted refrigerator needs to be opened or closed by a manual switch or a timing switch every time, which will inevitably cause the problems of poor user experience, tedious manual operation and waste of energy consumption of the vehicle-mounted refrigerator.

[0048] Therefore, the application provides a control method of a vehicle-mounted refrigerator to solve the problems of poor user experience, tedious manual operation and waste of energy consumption of the vehicle-mounted refrigerator caused by the manual switch.

[0049] First, a control method of a vehicle-mounted refrigerator provided in an embodiment of the application will be introduced.

[0050] It should be noted that the control method for a vehicle-mounted refrigerator provided in this embodiment of the invention is applied to a vehicle-mounted refrigerator equipped with a camera device, which is fixed inside the refrigerator and can capture images of the interior bottom and interior sidewalls. In specific applications, the camera device can be any electronic device currently capable of capturing images in real time to obtain YUV image data.

[0051] Furthermore, to achieve image data transmission, the camera device fixed inside the vehicle refrigerator, which can capture images of the interior bottom and side walls, needs to be connected to a control terminal. This connection technology can be Bluetooth, a local area network (LAN), or a server. The control terminal can be an electronic device such as a mobile phone or laptop. Of course, the connection technology between the camera device and the control terminal in this embodiment can be any technology that connects the camera device and the control terminal; no limitation is made here.

[0052] See Figure 1 , Figure 1 This is a flowchart illustrating a control method for a vehicle-mounted refrigerator according to an embodiment of the present invention, as shown below. Figure 1 As shown, this method is applied to a vehicle-mounted refrigerator equipped with a camera device. The camera device is fixed inside the vehicle-mounted refrigerator, capable of capturing images of the interior bottom and interior sidewalls, and is connected to a control terminal. The control method includes the following steps:

[0053] Step S101: When the preset camera shooting conditions are met, control the camera device to acquire the internal bottom image and / or internal side wall image of the vehicle refrigerator.

[0054] In this embodiment, a camera device (such as a webcam) electrically connected to the control terminal is installed inside the vehicle refrigerator. The shooting angle of the camera device needs to be adjusted so that it can at least capture the bottom and side walls (also referred to as the internal bottom or internal side walls) of the vehicle refrigerator used for placing items. Then, the control terminal is connected to the camera device via electrical connection. After that, a shooting condition for the camera device is set, that is, when the control terminal detects that the vehicle refrigerator with the camera device installed inside has performed some specific operation, it uses this as a trigger command (also understood as a shooting command) for the camera device to start shooting. Then, it controls the camera device to start, and the camera device completes the shooting of the internal bottom or internal side walls of the vehicle refrigerator, thereby obtaining an image of the internal bottom and / or internal side walls of the vehicle refrigerator in YUV data format.

[0055] The control method of the vehicle-mounted refrigerator provided in the embodiment is specifically used for detecting whether the vehicle-mounted refrigerator is placed with articles in real time, and different operations are performed according to different situations of whether the vehicle-mounted refrigerator is placed with articles, that is, when the vehicle-mounted refrigerator is placed with articles, the vehicle-mounted refrigerator is started in time, and when the vehicle-mounted refrigerator is not placed with articles, the vehicle-mounted refrigerator is turned off in time, so as to realize the purpose of reducing the waste of battery energy of the vehicle-mounted refrigerator while ensuring that the vehicle-mounted refrigerator is fully utilized. Therefore, the preset photographing condition of the camera shooting device can be a photographing condition triggered by an operation action of the vehicle-mounted refrigerator, and of course, the photographing condition can also be a photographing condition triggered by other factors in the vehicle-mounted refrigerator, for example, can be a pressure sensing factor of the bottom and / or the side wall in the vehicle-mounted refrigerator (when the pressure sensed by the side wall or the bottom is greater than a certain value, it indicates that the side wall or the bottom can be placed with articles at this time, that is, the camera shooting device can be triggered to shoot), or can also be an odor detection factor in the vehicle-mounted refrigerator, and the like.

[0056] As a preferred example, the preset photographing condition of the camera shooting device in the embodiment of the application can be that the vehicle-mounted refrigerator is powered on or the refrigerator door of the vehicle-mounted refrigerator is closed.

[0057] That is, when the preset photographing condition is met, the step of controlling the camera shooting device to capture the internal bottom image and / or the internal side wall image of the vehicle-mounted refrigerator can specifically include:

[0058] Step S101.1, when the control terminal detects that the vehicle-mounted refrigerator is powered on or the refrigerator door of the vehicle-mounted refrigerator is closed, a shooting instruction is sent to the camera shooting device;

[0059] Step S101.2, the camera shooting device receiving the shooting instruction is started, and the internal bottom and / or the internal side wall of the vehicle-mounted refrigerator is shot to obtain the internal bottom image and / or the internal side wall image.

[0060] Further, while the internal bottom image and / or the internal side wall image of the vehicle-mounted refrigerator is captured, image information of the internal bottom image and / or the internal side wall image is also obtained, and the image information includes a gray value Y of the image, a width W of the image, and a height H of the image.

[0061] Because the YUV data format image has only Y channel data to be obtained for input detection, and only W*H of the image is required for storage space, and the Y component information is the gray information of the image, therefore, when detection is performed, the black and white image detection is facilitated, and the memory cost of the image detection is reduced. Therefore, the internal bottom image and / or the internal side wall image of the vehicle-mounted refrigerator captured by the camera shooting device such as the camera in the embodiment of the application is preferably a YUV data format image.

[0062] Step S102, color block detection calculation is performed on the internal bottom image and / or the internal side wall image of the vehicle-mounted refrigerator to obtain the white block gray mean value and the black block gray mean value of the internal bottom image and / or the internal side wall image.

[0063] In this embodiment, after obtaining the internal bottom image and / or the internal side wall image of the vehicle-mounted refrigerator and the image information corresponding to the image by the above step S101, the internal bottom image and / or the internal side wall image of the vehicle-mounted refrigerator is subjected to black and white color block segmentation to obtain a color block image corresponding to the internal bottom image and / or the internal side wall image, wherein the color block image contains a plurality of black color blocks and a plurality of white color blocks arranged at intervals, and the size of the black color blocks and the white color blocks is the same; then, the image block gray mean value of each color block is calculated; then, the total gray mean value of all white color blocks and the total gray mean value of all black color blocks in the color block image are calculated according to the image block gray mean value corresponding to each of all white color blocks and all black color blocks in the color block image; finally, the total gray mean value of all white color blocks is taken as the white block gray mean value, and the total gray mean value of all black color blocks is taken as the black block gray mean value.

[0064] As a preferred example, the step of calculating the image block gray mean value of each color block can specifically include:

[0065] Step S102.1, dividing the entire area of each color block into a plurality of square small areas, and selecting a plurality of square small areas from the plurality of square small areas;

[0066] Step S102.2, calculating the image block gray mean value of each color block by using a single image block gray mean value calculation formula based on the selected plurality of square small areas.

[0067] The areas of the plurality of square small areas can be the same.

[0068] The image block gray mean value calculation formula can be specifically as follows:

[0069]

[0070] wherein, is the image block gray mean value of color block t in the color block image, m is the number of selected square small areas in color block t, n is the number of pixel points of each selected square small area in color block t, j is any one of the m selected square small areas in color block t, i is the pixel point number of each selected square small area in color block t, Y(ij)t is the gray value of the corresponding pixel i in the jth square sub-region in the color block t, the value of n is not less than 9, and the value of m is not less than 5.

[0071] Further, the calculation formula of the total gray mean value of all white color blocks or all black color blocks in the color block image can be specifically:

[0072]

[0073] wherein, is the total gray mean value of all white color blocks or all black color blocks, b is the total number of all white color blocks or all black color blocks contained in the color block image, t is the color block number, and t takes the value of 1, 2, …, K, is the image block gray mean value of the color block t in the color block image, and the color block t can be a white color block or a black color block.

[0074] In the embodiment, after obtaining the internal bottom image and / or the internal side wall image of the vehicle-mounted refrigerator, the internal bottom image and / or the internal side wall image can be first divided into a plurality of interval-arranged black and white color blocks, then the entire region of each color block (black color block or white color block) is regionally divided, and then a plurality of small regions are divided on the region of each color block. Preferably, in the embodiment of the application, the shape of the divided small regions is set to be square, and in other embodiments, it can be any other shape, for example, rectangular, parallelogram, etc. Then, for each color block, a few small regions with square shape (referred to as square small regions for short) are selected from the upper part, the middle part and the lower part of the entire region of the color block, respectively. For example, 2 square small regions are taken from the upper part of each color block, 1 square small region is taken from the middle part, and 2 square small regions are taken from the lower part, i.e. 5 square small regions are taken from each color block, and for example, the size of each square small region is 3*3. Then, the image block gray mean value of each white color block and black color block contained in the internal bottom image and / or the internal side wall image of the vehicle-mounted refrigerator can be calculated according to the above formula (1), and then the total gray mean value of all white color blocks in the internal bottom image and / or the internal side wall image of the vehicle-mounted refrigerator is calculated by using the formula (2), and the total gray mean value of all black color blocks is obtained in the same way. Then, the total gray mean value of the white color blocks and the total gray mean value of all black color blocks are respectively verified by threshold requirement according to the following step S103, and then the purpose of automatically and real-timely determining whether there is an article placed in the vehicle-mounted refrigerator is finally realized through the steps of black and white color block division and calculation.

[0075] It should be noted that in the embodiment of the present application, when the inside bottom image and / or the inside side wall image of the vehicle-mounted refrigerator is collected by the camera device in the above step S101, it can be that the inside bottom image and the inside side wall image of the vehicle-mounted refrigerator are collected at the same time, and then the operation processes of steps S102 and S103 are performed on the inside bottom image and the inside side wall image respectively, or it can also be that only the inside bottom image or the inside side wall image of the vehicle-mounted refrigerator is collected, and then the operation processes of steps S102 and S103 are performed, and the embodiment of the present application does not make specific limitation on this.

[0076] In step S103, it is judged whether the white block gray mean value and the black block gray mean value both satisfy the preset threshold requirement, and when the judgment result is yes, it is determined that the vehicle-mounted refrigerator has placed articles therein, and the vehicle-mounted refrigerator is started.

[0077] As a preferred example, the step of judging whether the white block gray mean value and the black block gray mean value both satisfy the preset threshold requirement in the embodiment of the present application can include:

[0078] In step S103.1, the total gray mean value of all white color blocks is compared with a first threshold X1, and the total gray mean value of all black color blocks is compared with a second threshold X2.

[0079] In step S103.2, if the total gray mean value of all white color blocks is within the range of the first threshold X1, and the total gray mean value of all black color blocks is within the range of the second threshold X2, it is determined that the vehicle-mounted refrigerator has placed articles therein.

[0080] The range of the first threshold X1 can be specifically 200 < X1 < 255, that is, the value of the first threshold X1 can be 201, 202, 205, 210, 215, 215.1, 215.5, 220, 225, 230, 235, 240, 245, 250, 255, a region composed of any two of the above numbers and any integer or decimal within the region, etc.; the range of the second threshold X2 can be specifically 0 < X2 < 50, that is, the value of the second threshold X2 can be 0, 1, 2, 2.1, 2.5, 2.55, 3, 3.5, 4, 5, 10, 15, 20, 25, 30, 40, 50, a region composed of any two of the above numbers and any integer or decimal within the region, etc.

[0081] After the above step S103, the control method of the vehicle-mounted refrigerator provided in the embodiment of the present application can further include the following steps:

[0082] Step S104, if the result is no, it is determined that the vehicle-mounted refrigerator is not placed in the article, and the vehicle-mounted refrigerator is closed to make the vehicle-mounted refrigerator power off.

[0083] In summary, in the control method of the vehicle-mounted refrigerator provided in the application, by using the camera device (for example, a camera) arranged in the vehicle-mounted refrigerator, the inside bottom and the inside side wall of the vehicle-mounted refrigerator are photographed in real time when the vehicle-mounted refrigerator is powered on or the refrigerator door thereof is closed, and then the inside bottom image and / or the inside side wall image of the vehicle-mounted refrigerator are collected, and then the white block gray mean value and the black block gray mean value of the inside bottom image and / or the inside side wall image are obtained by performing color block detection calculation on the collected inside bottom image and / or the inside side wall image, and then whether the vehicle-mounted refrigerator is placed with an article is judged according to the white block gray mean value and the black block gray mean value, if yes, the vehicle-mounted refrigerator is powered on to be opened, and if no, the vehicle-mounted refrigerator is powered off to be closed in time.
