[0055] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0056] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data used can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects.

[0057] Next, in conjunction with the accompanying drawings, a storage device camera angle adjustment method, device, and electronic device provided by an embodiment of the present application will be described in detail through specific embodiments and their application scenarios.

[0058] The camera angle adjustment method for a storage device provided by an embodiment of the present application. The execution subject of this camera angle adjustment method for the storage device can be an electronic device or a functional module or functional entity in the electronic device that can implement this camera angle adjustment method for the storage device. The electronic devices mentioned in the embodiments of the present application include, but are not limited to, the controller in the storage device, the processor in the storage device, the background server, the cloud server, etc. Hereinafter, taking the electronic device as the execution subject as an example, the camera angle adjustment method for the storage device provided by the embodiments of the present application will be described.

[0059] The storage device in this embodiment can be understood as a generalized refrigerated storage device, including, but not limited to, refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold storage cabinets, and refrigerated vending machines, etc. The storage device has a variety of structural forms and a wide range of applications.

[0060] Figure 1 It is a schematic flowchart of the camera angle adjustment method for the storage device provided by the embodiments of the present application. As Figure 1 shown, this camera angle adjustment method for the storage device includes: step 110, step 120, and step 130.

[0061] Step 110: Obtain a target image captured by the camera of the storage device.

[0062] Capture a target image through the camera of the storage device, and this target image will be used as the basis for subsequent analysis and adjustment.

[0063] Step 120: Obtain the histogram data of the target image, and based on the histogram data, determine whether there is an overexposed area in the target image.

[0064] The histogram of an image is a statistical chart used to represent the number of pixels at each brightness level in the image. In the histogram of an image, the horizontal axis represents different brightness levels, and the vertical axis represents the number of pixels with that brightness level.

[0065] The overexposed area usually refers to the area where the brightness of a part of the image is abnormally high or low due to light problems (too strong or too weak), resulting in the loss of details. In the histogram, if the peak is concentrated at the extreme of the brightness level, it may mean that most pixels are concentrated at these extreme brightness levels, resulting in fewer pixels at the intermediate brightness levels, thus affecting the contrast and details of the image.

[0066] By analyzing the histogram data, it can be determined whether there is an overexposed area in the image. If there is an obvious peak in the higher or lower part of the brightness level in the histogram, and the number of pixels corresponding to this peak is relatively large, it is considered that there is an overexposed area in the image.

[0067] Step 130: If there is an overexposed area in the target image, adjust the angle of the storage device camera according to the solar altitude angle at the moment when the target image is captured and the position information corresponding to the overexposed area.

[0068] The solar altitude angle refers to the angle between the sun's rays and the ground, which determines the incident direction and intensity of sunlight. The solar altitude angle changes with time, location, and season.

[0069] By analyzing the target image, the position information of the overexposed area in the image can be determined, and then it can be converted into the actual position in the field of view of the storage device camera. According to the solar altitude angle and the position information corresponding to the overexposed area, it can be determined how to adjust the angle of the storage device camera to reduce or avoid the overexposed area.

[0070] In the above technical solution, by analyzing the histogram of the target image to find the overexposed area in the target image, and then combining the solar altitude angle and the position information of the overexposed area to determine the angle adjustment of the storage device camera, not only reduces the impact of overexposure problems on the target image, improves the shooting quality of the storage device camera, but also enhances the applicability of the storage device camera under different lighting conditions.

[0071] In an embodiment of the present application, the obtaining the histogram data of the target image includes:

[0072] Segment the target image to obtain a plurality of segmented image regions;

[0073] Obtain the histogram data of each segmented image region.

[0074] It can be understood that image segmentation is the process of dividing an image into several non-overlapping regions, which can be divided based on the similarity of features such as color, texture, and shape. Segmenting the target image can divide the image into smaller, more easily processed and analyzed regions, thereby improving the accuracy of locating the specific position where the overexposure problem occurs.

[0075] For each segmented image region, obtain its histogram data. A histogram is a statistical chart used to represent the number of pixels at each brightness level in an image. By analyzing the histogram of each region, it can be determined whether there is an overexposure problem in that region, and then a more effective angle adjustment strategy for the storage device camera can be formulated according to the specific position or size of these regions.

[0076] In the above technical solution, by segmenting the target image captured by the storage device camera, it is divided into multiple image regions. For each segmented image region, its histogram data is respectively obtained, so as to identify the region with abnormal exposure, improve the accuracy of exposure detection, and provide a basis for subsequent adjustment of the angle of the storage device camera and improvement of the shooting quality of the storage device camera.

[0077] In an embodiment of the present application, the determining whether there is an exposure region in the target image according to the histogram data includes:

[0078] According to the histogram data of each segmented image region, determine whether there is an exposure problem in each segmented image region;

[0079] Output the image region with an exposure problem as the exposure region.

[0080] Judging whether there is an exposure problem in the region according to the histogram data of the segmented image region, and outputting the image region judged to have an exposure problem as the exposure region. The information of the exposure region can be used for subsequent camera angle adjustment or other image processing operations.

[0081] Figure 2 It is a schematic diagram of segmenting the target image provided by an embodiment of the present application. In some embodiments, as Figure 2 shown, the target image is segmented into 9 image regions, and the histogram data of the segmented image regions is obtained. According to the histogram, it can be seen that there are exposure problems in image region 1 and image region 2.

[0082] In the above technical solution, judging whether there is an exposure problem in each region according to the histogram data of each segmented image region, and outputting the identified region with an exposure problem as the exposure region improves the efficiency and accuracy of image processing, and provides a basis for subsequent adjustment of the angle of the storage device camera.

[0083] In an embodiment of the present application, the method further includes:

[0084] Obtain the longitude and latitude information of the storage device;

[0085] Determine the solar altitude angle according to the longitude and latitude information and the shooting time of the target image.

[0086] Optionally, obtain the longitude and latitude information of the storage device through the built-in positioning module of the storage device or other positioning technologies, and obtain the shooting time of the target image through the timestamp when the storage device camera takes a picture or other means.

[0087] In some embodiments, according to the longitude and latitude information and the shooting time of the target image, the calculation formula for determining the solar altitude angle is as follows:

[0088] sin h = sinφsinδ + cosφcosδcos t

[0089] Where φ represents the geographical latitude of the location of the storage device; δ represents the solar declination, which is equal to the latitude of the direct solar point; t represents the local time (hour angle), in hours; and h is the required solar altitude angle.

[0090] In the above technical solution, the longitude and latitude information of the storage device is obtained, and the solar altitude angle is calculated in combination with the shooting time of the target image, improving the accuracy of analyzing the lighting conditions and providing a basis for subsequent adjustment of the camera angle of the storage device and improvement of the shooting quality of the camera of the storage device.

[0091] In an embodiment of the present application, adjusting the angle of the camera of the storage device according to the solar altitude angle at the shooting time of the target image and the position information corresponding to the exposure area includes:

[0092] Determining a target rotation angle according to the solar altitude angle at the shooting time of the target image and the position information corresponding to the exposure area;

[0093] Adjusting the angle of the camera of the storage device according to the target rotation angle.

[0094] When the camera of the storage device takes a picture, the solar altitude angle will affect the distribution of light in the image, and thus affect the exposure of the target image. Figure 3 It is a schematic diagram of overexposure of the target image provided by the embodiment of the present application. As Figure 3 shown, at this solar altitude angle, the reflection angle of the sunlight reflected by the highest commodity horizontal plane in the storage device is consistent with the shooting angle of the camera of the storage device, resulting in overexposure of the image.

[0095] According to the solar altitude angle at the shooting time of the target image and the position information corresponding to the exposure area in the image, the angle that the camera of the storage device needs to rotate (i.e., the target rotation angle) can be determined through calculation and analysis. This process takes into account the influence of sunlight on the camera of the storage device, and realizes reducing or eliminating the exposure problem in the target image by adjusting the angle of the camera of the storage device.

[0096] In the above technical solution, the target rotation angle is determined by the solar altitude angle at the shooting time of the target image and the position information corresponding to the exposure area, and the angle of the camera of the storage device is adjusted, improving the shooting quality of the camera of the storage device, reducing the exposure problem, and enhancing the clarity of the target image.

[0097] In an embodiment of the present application, determining the target rotation angle according to the solar altitude angle at the time of shooting the target image and the position information corresponding to the exposure area includes:

[0098] Determine the relative position between the exposure area and the center point of the target image according to the solar altitude angle at the time of shooting the target image and the position information corresponding to the exposure area;

[0099] Determine the target rotation angle according to the relative position.

[0100] The solar altitude angle is the angle between the light ray directly hitting the ground by the sun and the ground (water) plane. The solar altitude angle at the time of shooting the target image will affect the specific position of the exposure area in the target image.

[0101] The exposure area in the target image can be determined by analyzing the histogram data of the image. The exposure area will appear as an area where pixels with too high (overexposed) or too low (underexposed) brightness are aggregated on the histogram. The center point of the target image is usually the position of the geometric center of the image, that is, at half of the width and height of the image. The relative position between the exposure area and the center point of the target image can be completed by comparing the coordinates of the center of the exposure area (or a representative point) with the center point of the image, and obtaining relative position information such as horizontal offset and vertical offset.

[0102] In some embodiments, the target rotation angle is determined by the following method:

[0103] Figure 4 It is a schematic diagram for determining the target rotation angle provided by an embodiment of the present application. As Figure 4 shown, the dotted line box in the figure is the movable shooting field (range) of the storage device camera, the solid line box is the range of the target image shot by the storage device camera, and N° is the maximum movable angle of the storage device camera.

[0104] Segment the target image to obtain 9 segmented image areas, namely: upper left area, upper middle area, upper right area, left middle area, middle area, right middle area, lower left area, lower middle area and lower right area. Obtain the histogram of each image area respectively, and judge whether there is an exposure problem in the image area according to the histogram.

[0105] Specifically, control the storage device camera to rotate in the opposite direction of the relative position between the exposure area and the center point of the target image, and the rotation range is within the maximum movable angle N° of the storage device camera. Increase step by step with an angle change of 1°, until there is no longer an exposure problem in the target photo shot by the storage device camera, and determine the angle of rotation of the storage device camera as the target rotation angle.

[0106] Taking the upper left area having an exposure problem as an example, the current upper left area is the exposure area. AsFigure 4 As shown by the arrow in the figure, the storage device camera rotates in the opposite direction to the relative position of the exposure area and the center point of the target image. When the upper left area is the exposure area, the rotation direction of the storage device camera is lower right, and the rotation range is within the maximum movable angle N° of the storage device camera, increasing step by step with an angle change of 1° until there is no longer an exposure problem in the target photo taken by the storage device camera. At this time, the rotation angle of the storage device camera is the target rotation angle.

[0107] In the above technical solution, the relative position between the exposure area and the image center is determined, and based on the relationship between the solar altitude angle and the relative position, the target rotation angle is determined, and the storage device camera is adjusted according to the target rotation angle, optimizing the ability of the storage device to adapt to different lighting conditions and improving the shooting quality of the storage device camera.

[0108] In an embodiment of the present application, the method further includes:

[0109] Obtain a first image taken by the storage device camera after angle adjustment, and determine whether there is an exposure area in the first image;

[0110] If there is an exposure area in the first image, continue to adjust the angle of the storage device camera within the adjustable angle range of the storage device camera until there is no exposure area in the image taken by the storage device camera after angle adjustment.

[0111] After completing the adjustment of the storage device camera, take a new target image as the first image and determine whether there is an exposure area in the first image. If there is an exposure area in the first image, it means that the currently adjusted storage device camera has not completely eliminated the exposure problem.

[0112] Within the adjustable angle range of the storage device camera, continue to adjust the angle of the storage device camera. The selection of the new angle can be based on various factors such as the position, size, shape of the exposure area, and the solar altitude angle. Adjust the storage device camera based on this new angle and take another image for analysis again. Repeat the above steps until there is no longer an exposure area in the taken image.

[0113] Optionally, during the adjustment process, gradually narrow the adjustment angle interval or step size, so as to more finely adjust the rotation angle of the storage device camera.

[0114] In the above technical solution, the first image captured by the camera after angle adjustment is obtained, and it is determined whether there is an overexposed area in the image. If there is an overexposed area, the angle of the camera is continuously adjusted within the adjustable range of the camera angle, and the shooting and judgment steps are repeated until there is no overexposed area in the captured image. By adjusting the storage device camera multiple times, the overexposure problem in the image is effectively eliminated, and the shooting quality of the storage device camera is improved.

[0115] In the method for adjusting the angle of the storage device camera provided by the embodiment of the present application, the execution subject may be a device for adjusting the angle of the storage device camera.

[0139] In the above technical solution, the angle adjustment device of the storage device camera analyzes the exposure area in the target image through the histogram of the target image, and then combines the solar altitude angle and the exposure area position information to determine the angle for adjusting the camera of the storage device, which not only reduces the influence of the exposure problem on the target image, improves the shooting quality of the storage device camera, but also enhances the applicability of the storage device camera under different lighting conditions.
