Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of light-emitting detection, in particular to a MiniLED light-emitting detection method and device, electronic equipment and medium. BACKGROUND

[0002] MiniLED technology is an improvement and optimization of traditional LED display technology. By using smaller LED lamp beads and denser arrangement, higher brightness and contrast are provided to meet the needs of users for high-quality and innovative display technology.

[0003] When the MiniLED light-emitting panel has uneven brightness or color variation, the display image or video will have obvious brightness difference or color spots in different areas. Therefore, in order to ensure the visual effect of the display screen, it is particularly important to detect the light-emitting uniformity of the MiniLED light-emitting panel before it is shipped. SUMMARY

[0004] In order to improve the accuracy of light-emitting detection, the present application provides a MiniLED light-emitting detection method, device, electronic equipment and medium.

[0005] In a first aspect, the present application provides a MiniLED light-emitting detection method, which adopts the following technical solution:

[0006] A MiniLED light-emitting detection method, comprising:

[0007] Obtaining a to-be-detected image, the to-be-detected image being an image of a to-be-detected MiniLED light-emitting panel, the to-be-detected MiniLED light-emitting panel comprising a plurality of light-emitting lamp beads;

[0008] Importing the to-be-detected image into a preset coordinate system to determine a plurality of preset key point coordinates, each preset key point coordinate corresponding to a light-emitting lamp bead;

[0009] Adjusting each preset key point coordinate according to a preset coordinate adjustment value to obtain a to-be-detected light-emitting point coordinate corresponding to each preset key point coordinate;

[0010] Determining a to-be-detected light-emitting area according to each to-be-detected light-emitting point coordinate, and cutting the to-be-detected image according to the to-be-detected light-emitting area to obtain a to-be-detected light-emitting image corresponding to the to-be-detected light-emitting area;

[0011] Dividing the to-be-detected light-emitting image into at least two area images, and identifying a region brightness corresponding to each area image, each area image corresponding to at least one light-emitting lamp bead;

[0012] The region luminance corresponding to each region image is compared to determine whether there is an abnormal light-emitting region in the to-be-detected light-emitting image, and if so, at least one light-emitting lamp bead corresponding to the abnormal light-emitting region is determined as an abnormal lamp bead.

[0013] By adopting the technical solution, the preset key point coordinates on the to-be-detected MiniLED light-emitting plate can be accurately positioned by importing the to-be-detected image into the preset coordinate system, and then the to-be-detected light-emitting region on the to-be-detected MiniLED light-emitting plate is positioned by the preset key point coordinates, and then the luminance of the to-be-detected region is detected instead of detecting the luminance of a single lamp bead, so as to reduce the complexity of the detection work, thereby improving the work efficiency of the light-emitting detection of the to-be-detected MiniLED light-emitting plate. After the to-be-detected region image is divided, the luminance of different region images is compared to determine whether there is an abnormal light-emitting region in the to-be-detected region. By reducing the detection range, the abnormal lamp bead with problems on the to-be-detected MiniLED light-emitting plate can be quickly positioned and recognized. By increasing the probability of finding the abnormal lamp bead, the accuracy of detecting the to-be-detected MiniLED light-emitting plate is improved.

[0014] In a possible implementation manner, before the to-be-detected image is imported into the preset coordinate system to determine the plurality of preset key point coordinates, the method further includes:

[0015] Obtaining a detection environment luminance and identifying an overall uniform luminance value corresponding to the to-be-detected image;

[0016] Determining a luminance difference between the detection environment luminance and the overall uniform luminance value;

[0017] When the luminance difference is lower than a preset luminance value, a prompt information is generated.

[0018] By adopting the technical solution, since the MiniLED light-emitting plate can provide better visibility and readability in the case that the light in the detection region is relatively dark, that is, the detection environment luminance will affect the judgment of whether there is an abnormal lamp bead in the MiniLED light-emitting plate. Therefore, it is necessary to judge whether the luminance of the detection region and the luminance of the to-be-detected image are suitable according to the luminance difference, and generate a prompt information when they are not suitable, so as to remind the relevant staff to timely adjust the luminance of the detection environment or the luminance of the to-be-detected image, thereby improving the accuracy of the light-emitting detection.

[0019] In a possible implementation manner, the adjusting each preset key point coordinate according to the preset coordinate adjustment value includes:

[0020] The preset coordinate adjustment value is identified to determine a corresponding adjustment value type, and the adjustment value type includes x value adjustment and y value adjustment; based on the adjustment value type and each preset key point coordinate, the plurality of preset key point coordinates are classified to obtain two coordinate groups, each coordinate group includes at least two preset key point coordinates, and the coordinate values corresponding to the adjustment value type in the at least two preset key point coordinates included in one coordinate group are consistent;

[0021] According to the target adjustment coordinate value corresponding to each of the two coordinate groups, the adjustment type of each coordinate group is determined, the target adjustment coordinate value corresponding to the coordinate group is the coordinate value corresponding to the adjustment value type in the coordinate group, and the adjustment type includes increase and decrease; and the at least two preset key point coordinates included in each coordinate group are adjusted according to the adjustment type of each coordinate group and the preset coordinate adjustment value.

[0022] By adopting the above technical solution, the plurality of preset key point coordinates to be adjusted are grouped by the adjustment value type first, and then the preset key point coordinates in the group are adjusted according to the same adjustment mode, so that the adjustment mode does not need to be determined once before adjusting each preset key point coordinate, thereby facilitating to improve the speed of adjusting the coordinates. Since the adjustment modes corresponding to different coordinate groups are different, the preset key point coordinates in the group are adjusted according to the respective corresponding adjustment mode after grouping, which can reduce repeated operations, thereby facilitating to improve the accuracy of coordinate adjustment.

[0023] In a possible implementation manner, after adjusting each preset key point coordinate according to the preset coordinate adjustment value, the method further includes:

[0024] According to each preset key point coordinate obtained after adjustment, an initial to-be-detected light-emitting area is determined, and an initial area of the initial to-be-detected light-emitting area is calculated;

[0025] A key area is calculated according to the preset key point coordinate;

[0026] The initial area is compared with the key area to obtain an area ratio, and if the area ratio exceeds a preset area ratio range, an expansion adjustment value instruction is generated to remind a relevant staff to optimize the preset coordinate adjustment value according to the adjustment value instruction.

[0027] By adopting the technical scheme, since the preset coordinate adjustment value is preset and is not formulated for a certain to-be-detected Mini LED light-emitting plate, when the model of the to-be-detected Mini LED light-emitting plate changes, the preset coordinate adjustment value formulated in advance may need to be adjusted in time. The area ratio facilitates supervision of the light-emitting detection process without the need for manual monitoring of the detection process all the time. In addition, the area ratio is compared with the preset area ratio to discover abnormalities in time, and the accuracy is higher than manual monitoring.

[0028] In a possible implementation manner, when there are multiple to-be-detected Mini LED light-emitting plates containing abnormal lamp beads, after the at least one light-emitting lamp bead corresponding to the abnormal light-emitting area is determined as an abnormal lamp bead, the method further includes:

[0029] Obtaining abnormal coordinates of the abnormal lamp bead in each to-be-detected Mini LED light-emitting plate, and comparing the abnormal coordinates contained in each to-be-detected Mini LED light-emitting plate to determine whether there are similar coordinates between different to-be-detected Mini LED light-emitting plates. If yes, the position of a welding point corresponding to the similar coordinates is obtained;

[0030] Obtaining working data of each to-be-detected Mini LED light-emitting plate, matching the working data of each to-be-detected Mini LED light-emitting plate with corresponding preset standard data, and determining whether there are similar abnormal data between different to-be-detected Mini LED light-emitting plates. If yes, abnormal data feedback information is generated. The working data includes working voltage and working temperature, and the abnormal data is working data exceeding the corresponding preset standard data;

[0031] The feedback information is constituted according to the position of the welding point and the abnormal data feedback information, and is fed back to a terminal device of a relevant worker.

[0032] By adopting the technical scheme, whether there are similar coordinates between different to-be-detected Mini LED light-emitting plates is determined, so as to find the commonalities between different to-be-detected Mini LED light-emitting plates. The position of the welding point corresponding to the similar coordinates is obtained, so as to further analyze and identify specific abnormal reasons. The working data is used to further analyze the abnormal reasons, and the feedback information constituted is fed back to a terminal device of a relevant worker, so as to help the relevant worker understand and solve the problem of the abnormal light-emitting plate, thereby the response time and processing efficiency of the relevant worker can be improved, and production interruption and resource waste can be reduced.

[0033] In a possible implementation manner, the method further includes:

[0034] Obtain a plurality of abnormal Mini LED light-emitting panels detected in a preset time period, and the abnormal Mini LED light-emitting panel is a Mini LED light-emitting panel containing an abnormal lamp bead;

[0035] Identify abnormal coordinates corresponding to the abnormal lamp bead in each abnormal Mini LED light-emitting panel, and record the number of abnormalities of each abnormal coordinate;

[0036] Sort all abnormal coordinates according to the number of abnormalities to obtain an abnormal sequence, and feed back the abnormal sequence to a terminal device of a related worker.

[0037] By adopting the above technical solution, by analyzing the abnormal positions of the abnormal lamp beads in the plurality of abnormal Mini LED light-emitting panels, and sorting all abnormal coordinates according to the number of abnormalities, the abnormal coordinates with a higher number of abnormalities can be determined, and by feeding back the determined abnormal sequence to the related worker, the related personnel can be reminded to pay more attention to and prioritize the processing of these abnormal situations when performing light-emitting detection on the light-emitting panel, thereby improving the work efficiency when determining the abnormal lamp bead.

[0079] The following will be described in detail in combination with the accompanying Figures 1-5 The present application will be further described in detail.

[0080] Those skilled in the art can make modifications to the embodiments of the present application without creative contribution after reading the present specification, but as long as the modifications are within the scope of the claims of the present application, they are protected by the patent law.

[0081] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0082] Specifically, the embodiment of the present application provides a Mini LED light emitting detection method, which is executed by an electronic device. The electronic device can be a server or a terminal device. The server can be a physical server, a server cluster composed of multiple physical servers, a distributed system, or a cloud server providing cloud computing services. The terminal device can be a smartphone, a tablet computer, a notebook computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected through wired or wireless communication, and the embodiment of the present application does not limit this.

[0083] Reference Figure 1 , Figure 1 is a flowchart of a Mini LED light emitting detection method in the embodiment of the present application. The method comprises steps S110-S160, wherein:

[0084] Step S110: acquiring a to-be-detected image.

[0085] The to-be-detected image is an image of a to-be-detected Mini LED light emitting panel, and the to-be-detected Mini LED light emitting panel comprises a plurality of light emitting beads.

[0086] Specifically, the image of the to-be-detected Mini LED light emitting panel can be collected by an image collection device and uploaded to the electronic device, or uploaded to the electronic device by relevant staff. The specific uploading method is not limited in the embodiment of the present application. The Mini LED light emitting panel is composed of densely arranged LED beads, so the to-be-detected Mini LED light emitting panel comprises a plurality of light emitting beads, that is, the image of the to-be-detected Mini LED light emitting panel also comprises a plurality of light emitting beads.

[0087] Step S120: importing the to-be-detected image into a preset coordinate system to determine a plurality of preset key point coordinates, each preset key point coordinate corresponding to a light emitting bead.

[0088] Specifically, the preset key point coordinates can be set by relevant technical personnel, and the number of preset key point coordinates is not limited in the embodiment of the present application. The same to-be-detected image can need to be determined multiple times, and the preset key point coordinates determined each time are different. The coverage area of the preset key point coordinates determined multiple times corresponds to the entire to-be-detected image. The specific preset coordinate system is not limited in the embodiment of the present application, as long as the preset key point coordinates corresponding to the preset key point can be determined according to the preset coordinate system.

[0089] When determining the preset key points contained in the to-be-detected image, the preset key points are projected in the to-be-detected image by projection to obtain a to-be-detected image with projected points, and then the to-be-detected image with projected points is introduced into a preset coordinate system for coordinate determination. The specific manner of determining the preset key points contained in the to-be-detected image is not limited in the embodiments of the present application, and any manner capable of determining can be used.

[0090] In order to improve the accuracy of light emission detection, before introducing the to-be-detected image into the preset coordinate system to determine the coordinates of the plurality of preset key points, the following steps are further included:

[0091] The detection environment brightness is obtained, and the overall uniform brightness value corresponding to the to-be-detected image is identified. The brightness difference between the detection environment brightness and the overall uniform brightness value is determined. When the brightness difference exceeds the preset brightness range, a prompt information is generated.

[0092] Specifically, since the interval distance between each LED light-emitting lamp bead in the Mini LED light-emitting plate is relatively small, when an abnormality occurs in a certain LED light-emitting lamp bead in the Mini LED light-emitting plate, the light-emitting area of the LED light-emitting lamp bead will become dark. At this time, if the brightness of the entire Mini LED light-emitting plate itself is relatively dark, the to-be-detected image as a whole will also be relatively dark. In this case, it is difficult to find abnormal LED light-emitting lamp beads in the Mini LED light-emitting plate. Therefore, when performing light emission detection on the Mini LED light-emitting plate, the light emission brightness of the Mini LED light-emitting plate needs to be considered. In addition, the brightness of the detection environment also affects the detection result.

[0093] The detection environment brightness is the brightness of the environment in which the detection work is performed. The detection environment brightness can be collected by a brightness sensor arranged in the detection environment and uploaded to an electronic device. The overall uniform brightness value corresponding to the to-be-detected image is the brightness value of the to-be-detected image. The to-be-detected image can be converted into a grayscale image to map each pixel value in the to-be-detected image to a corresponding grayscale value. The overall uniform brightness value of the to-be-detected image is calculated according to the grayscale value corresponding to each pixel. The specific identification manner is not limited in the embodiments of the present application, and can be set by a person skilled in the art.

[0094] The luminance difference is used to determine whether the current detection environment luminance is suitable for the light emitting detection of the Mini LED light emitting panel to be detected. When the luminance difference exceeds the preset luminance range, it represents how much the difference between the current detection environment luminance and the overall uniform luminance value corresponding to the image to be detected is, or is too small. In this case, the accuracy of the light emitting detection is low. The promotion information generated is used to remind the relevant staff to adjust the monitoring area environment luminance or adjust the overall uniform luminance value corresponding to the image to be detected, so that the luminance difference between the two is restored to the preset luminance range. The specific luminance limit of the preset luminance range is not limited in the embodiments of the present application, and can be set by the relevant technical personnel.

[0095] The prompt information can be broadcast reminder information or text reminder information, and the specific form is not limited in the embodiments of the present application, as long as the prompt information can be fed back to the corresponding staff.

[0096] Step S130: adjusting each preset key point coordinate according to the preset coordinate adjustment value to obtain the to-be-detected light emitting point coordinate corresponding to each preset key point coordinate.

[0097] Specifically, the preset coordinate adjustment value is used to represent the specification of adjusting the preset key point coordinate. The preset coordinate adjustment value includes the to-be-adjusted coordinate type and the to-be-adjusted amount. For example, the preset coordinate adjustment value can be represented by x 0.5 , or y 0.5 , wherein x 0.5 is used to represent that the x coordinate value in the preset key point coordinate is adjusted up or down by 0.5. The to-be-detected light emitting point coordinate is a coordinate that has been adjusted and corresponds to the preset key point coordinate one by one.

[0098] In order to improve the accuracy of coordinate adjustment, adjusting each preset key point coordinate according to the preset coordinate adjustment value specifically includes steps S1301-S1304, as shown in Figure 2 , wherein:

[0099] Step S1301: identifying the preset coordinate adjustment value to determine the corresponding adjustment value type, and the adjustment value type includes x value adjustment and y value adjustment.

[0100] Specifically, when determining the adjustment value type corresponding to the preset coordinate adjustment value, the key feature of the preset coordinate adjustment value can be identified. When the feature recognition result is x, the adjustment value type corresponding to the preset coordinate adjustment value is x value adjustment. When the feature recognition result is y, the adjustment value type corresponding to the preset coordinate adjustment value is y value adjustment.

[0101] Step S1302: based on the adjustment value type and each preset key point coordinate, classify the plurality of preset key point coordinates to obtain two coordinate groups, each coordinate group contains at least two preset key point coordinates, and the at least two preset key point coordinates contained in one coordinate group have the same coordinate value corresponding to the adjustment value type.

[0102] Specifically, different adjustment value types correspond to different grouping manners, and when classifying the plurality of preset key point coordinates, the grouping manner needs to be determined according to the adjustment value type. When the adjustment value type is x value adjustment, the corresponding grouping manner is to group all preset key point coordinates with the same x value. When the adjustment value type is y value adjustment, the corresponding grouping manner is to group all preset key point coordinates with the same y value. For example, the preset key point coordinates are (3, 1), (5, 1), (3, 3), and (5, 3). When the adjustment value type is y value adjustment, the y coordinate values in each group of at least two preset key point coordinates need to be consistent, so (3, 1) and (5, 1) are grouped together, and (3, 3) and (5, 3) are grouped together. Since in the embodiment of the present application, a plurality of rectangular regions need to be divided from the to-be-monitored image, and light emission detection is performed on the plurality of rectangular regions to realize light emission detection on the entire to-be-detected image, the number of preset key point coordinates is at least 4, that is, each group contains at least two preset key point coordinates.

[0103] Step S1303: determining the adjustment type of each coordinate group according to the target adjustment coordinate value corresponding to each of the two coordinate groups. The target adjustment coordinate value corresponding to a coordinate group is the coordinate value corresponding to the adjustment value type in the coordinate group, and the adjustment type includes increase and decrease.

[0104] Specifically, the target adjustment coordinate value corresponding to a coordinate group is the same coordinate value in the at least two preset key point coordinates in the coordinate group. For example, the target adjustment coordinate value of the coordinate group of (3, 3) and (5, 3) is 3.

[0105] After comparing the target adjustment coordinate values corresponding to the two coordinate groups, the adjustment type corresponding to the smaller target adjustment coordinate value is determined as increase, and the adjustment type corresponding to the larger target adjustment coordinate value is determined as decrease. For example, the target adjustment value corresponding to the coordinate group a of (3, 1) and (5, 1) is 1, and the target adjustment value corresponding to the coordinate group b of (3, 3) and (5, 3) is 3. After comparing the target adjustment values corresponding to the coordinate group a and the coordinate group b, it is found that the target adjustment value of the coordinate group a is smaller, so the adjustment type of the coordinate group a is determined as increase, and the adjustment type of the coordinate group b is determined as decrease.

[0106] Since the to-be-detected image is the entire to-be-detected Mini LED light-emitting panel, the to-be-detected image also contains all the light-emitting lamp beads on the light-emitting panel, and the more the number of light-emitting lamp beads, the more difficult the detection process is. Therefore, when detecting the to-be-detected Mini LED light-emitting panel according to the to-be-detected image, the to-be-detected image needs to be divided before detection. In the embodiment of the present application, the division area is determined based on the adjusted preset key point coordinates. If the division area is too large, it may affect the accuracy of the light-emitting detection. If the division area is too small, it may affect the work efficiency of the light-emitting detection. Therefore, in order to facilitate the supervision of the light-emitting detection process, the embodiment of the present application also includes:

[0107] According to the adjusted preset key point coordinates, an initial to-be-detected light-emitting area is determined, and an initial area of the initial to-be-detected light-emitting area is calculated. The area ratio is obtained by comparing the initial area with the key area. If the area ratio exceeds the preset area ratio range, an expansion adjustment value instruction is generated to remind the relevant staff to optimize the preset coordinate adjustment value according to the adjustment value instruction.

[0108] Specifically, the initial to-be-detected light-emitting area is surrounded by the adjusted preset key point coordinates. For example, when the adjusted 4 preset key point coordinates are (3, 1), (5, 1), (3, 3) and (5, 3), the two side lengths of the initial to-be-detected light-emitting area are determined to be 2 and 2 respectively according to the 4 coordinates. Therefore, the initial area of the to-be-detected light-emitting area is 4. The preset key point coordinates are the key point coordinates that have not been adjusted. The way to calculate the key area can refer to the way to calculate the initial area, which is not repeated here. If the area ratio obtained by comparing the initial area with the key area is less than the minimum limit of the preset area ratio range, it indicates that the initial area is small. If the area ratio obtained by comparing the initial area with the key area is greater than the maximum limit of the preset area ratio range, it indicates that the initial area is large. Since the preset coordinate adjustment value is preset and is not prepared for a certain to-be-detected Mini LED light-emitting panel, when the model of the to-be-detected Mini LED light-emitting panel changes, the preset coordinate adjustment value prepared in advance may need to be adjusted in time. The area ratio is convenient for supervising the light-emitting detection process without manual monitoring of the detection process. In addition, the area ratio is compared with the preset area ratio to find abnormalities in time, which is more accurate than manual monitoring.

[0109] Step S1304: Adjusting at least two preset key point coordinates included in each coordinate group according to the adjustment type of each coordinate group and the preset coordinate adjustment value.

[0110] Specifically, according to the adjustment type and the preset coordinate adjustment value corresponding to each coordinate group, the target adjustment value corresponding to each coordinate group is adjusted, for example, the two preset key point coordinates (3, 1) and (5, 1) in the coordinate group a can determine that the target adjustment value of the coordinate group a is 1, and the adjustment type corresponding to the coordinate group a is increase, and the preset coordinate adjustment value is 0.1. After increasing the target adjustment value in the coordinate group a by 0.1, the adjusted preset key point coordinates are (3, 1.1) and (5, 1.1).

[0111] Step S140: determining a to-be-detected light-emitting region according to each to-be-detected light-emitting point coordinate, and intercepting the to-be-detected image according to the to-be-detected light-emitting region to obtain a to-be-detected light-emitting image corresponding to the to-be-detected light-emitting region.

[0112] Specifically, the to-be-detected light-emitting region is surrounded by each to-be-detected light-emitting point coordinate, for example, Figure 3 As shown in Figure 3 The gray region is the to-be-detected light-emitting region, and the to-be-detected light-emitting point is the vertex of the to-be-detected light-emitting region. The to-be-detected image is intercepted according to the to-be-detected light-emitting region, that is, the image corresponding to the to-be-detected light-emitting region is determined from the to-be-detected image. The to-be-detected light-emitting image only contains the to-be-detected light-emitting region, while the to-be-detected image contains multiple different to-be-detected light-emitting regions.

[0113] Step S150: regionally dividing the to-be-detected light-emitting image to obtain at least two region images, and identifying the region brightness corresponding to each region image, each region image corresponding to at least one light-emitting lamp bead.

[0114] Specifically, when the to-be-detected light-emitting image is regionally divided, it can be divided according to the horizontal coordinate direction of the to-be-detected light-emitting point coordinate, or it can be divided according to the vertical coordinate direction of the to-be-detected light-emitting point coordinate. Since the preset key point coordinate corresponds to the light-emitting LED lamp bead, and the preset coordinate adjustment value is generally small, the to-be-detected light-emitting image is generally a blank region in the to-be-detected Mini LED light-emitting panel. Since the light source provided by each light-emitting LED lamp bead in the to-be-detected Mini LED light-emitting panel will be scattered, the blank region will be illuminated. Because the scattering range of the light-emitting LED lamp bead is limited, there is a corresponding relationship between the blank region and the light-emitting lamp bead,

[0115] Step S160: comparing the region brightness corresponding to each region image to determine whether there is an abnormal light-emitting region in the to-be-detected light-emitting image. If so, at least one light-emitting lamp bead corresponding to the abnormal light-emitting region is determined as an abnormal lamp bead.

[0116] Specifically, since the area image corresponds to a light-emitting lamp bead, the area image is divided, and the corresponding light-emitting lamp bead is also divided. By comparing the area brightness of the area image, it is convenient to compare whether the light-emitting brightness of the divided light-emitting lamp bead is uniform. When the to-be-detected light-emitting image is divided, it can be divided into two area images, as shown in Figure 3 , it can also be divided into multiple area images. The number of divided images is not specifically limited in the embodiments of the present application. The abnormal light-emitting area is a divided area with different area brightness corresponding to other divided areas. The number of abnormal light-emitting areas can be 0, 1 or multiple. The specific number is not specifically limited in the embodiments of the present application.

[0117] After determining the abnormal light-emitting area, the abnormal light-emitting lamp bead corresponding to the abnormal light-emitting area is determined according to the correspondence between the light-emitting lamp bead and the divided area. The correspondence between the light-emitting lamp bead and the divided area includes the light-emitting lamp bead corresponding to each divided area. It can be recorded and generated after the to-be-detected light-emitting image is divided, or it can be input by a related technician in advance. The specific forming method is not specifically limited in the embodiments of the present application.

[0118] For the embodiments of the present application, by importing the to-be-detected image into the preset coordinate system, the preset key point coordinates on the to-be-detected Mini LED light-emitting plate can be accurately positioned. After the to-be-detected light-emitting area on the to-be-detected Mini LED light-emitting plate is determined by the preset key point coordinates, the brightness of the to-be-detected area is detected, instead of the brightness of a single lamp bead, which facilitates reducing the complexity of the detection work, thereby facilitating improving the work efficiency when detecting the to-be-detected Mini LED light-emitting plate. After dividing the to-be-detected area image, the brightness of different area images is compared to determine whether there is an abnormal light-emitting area in the to-be-detected area. By reducing the detection range, the abnormal lamp bead with problems on the to-be-detected Mini LED light-emitting plate can be quickly positioned and recognized. By improving the probability of discovering abnormal lamp beads, the accuracy of detecting the to-be-detected Mini LED light-emitting plate is improved.

[0119] Further, in order to improve the work efficiency when determining the abnormal lamp bead, the method provided by the embodiments of the present application further comprises:

[0120] obtaining a plurality of abnormal Mini LED light-emitting plates detected in a preset time period, the abnormal Mini LED light-emitting plate being a Mini LED light-emitting plate containing an abnormal lamp bead; obtaining an abnormal coordinate corresponding to the abnormal lamp bead in each abnormal Mini LED light-emitting plate, and recording the number of abnormalities of each abnormal coordinate; sorting all abnormal coordinates according to the number of abnormalities to obtain an abnormal sequence, and feeding back the abnormal sequence.

[0121] Specifically, the preset time period can be 24 hours or 48 hours, and the specific duration is not limited in the embodiments of the present application and can be set by a relevant technical person. For ease of comparison, the plurality of abnormal Mini LED light-emitting plates are light-emitting plates with consistent sizes, and the number of abnormal lamp beads in each abnormal Mini LED light-emitting plate can be one or multiple. The number of times of abnormal coordinates appearing is used to represent the number of times of abnormal light-emitting lamp beads corresponding to the current coordinate position. When sorting all abnormal coordinates according to the number of times of abnormality, bubble sort, quick sort, etc. can be used, and the specific sorting method is not limited in the embodiments of the present application as long as the abnormal sequence can be determined. The abnormal sequence can be a sequence with the number of times of abnormality from more to less or a sequence with the number of times of abnormality from less to more, which is not limited in the embodiments of the present application.

[0122] The abnormal sequence can be fed back to the terminal device of the relevant maintenance personnel, which can remind the relevant personnel to pay more attention to and preferentially handle these abnormal situations when performing light-emitting detection on the light-emitting plate, thereby improving the work efficiency when determining abnormal lamp beads.

[0123] Further, in order to reduce production interruption and resource waste, the method provided in the embodiments of the present application further includes: acquiring abnormal coordinates of abnormal lamp beads in each to-be-detected Mini LED light-emitting plate, and comparing the abnormal coordinates contained in each to-be-detected Mini LED light-emitting plate to determine whether there are similar coordinates between different to-be-detected Mini LED light-emitting plates, and if so, acquiring the welding point positions corresponding to the similar coordinates; acquiring working data of each to-be-detected Mini LED light-emitting plate, matching the working data of each to-be-detected Mini LED light-emitting plate with corresponding preset standard data, and determining whether there are similar abnormal data between different to-be-detected Mini LED light-emitting plates, and if so, generating abnormal data feedback information, the working data including working voltage and working temperature, and the abnormal data being working data exceeding the corresponding preset standard data; constructing feedback information according to the welding point positions and the abnormal data feedback information, and feeding back the feedback information to the terminal device of the relevant personnel.

[0124] Specifically, after detecting the abnormal lamp bead, the abnormal coordinates corresponding to the abnormal lamp bead are recorded and stored in the electronic device, and the abnormal data can be directly called from the electronic device when needed. Whether similar coordinates exist between different Mini LED light-emitting panels to be detected, that is, whether the abnormal coordinates of the abnormal lamp beads in different Mini LED light-emitting panels to be detected are consistent, if the abnormal lamp beads in different Mini LED light-emitting panels to be detected all appear at the same position, the welding point corresponding to the abnormal coordinates may be abnormal, therefore, the similar coordinates need to be recorded, so that after being fed back to the relevant staff, the relevant staff can check whether the corresponding welding point is abnormal according to the similar coordinates, so as to reduce more abnormal lamp beads in the future.

[0125] The working data of the Mini LED light-emitting panel to be detected can be collected and recorded by the sensor arranged at the Mini LED light-emitting panel to be detected. The working data can be voltage, working temperature, etc. The preset standard data corresponding to different working data is different. When an abnormal Mini LED light-emitting panel is detected, the working data of the abnormal Mini LED light-emitting panel is recorded, and whether there is abnormal data is judged according to the preset standard data corresponding to each working data. The abnormal Mini LED light-emitting panel may have one abnormal data, or may have multiple abnormal data, or may have no abnormal data. The abnormal data corresponding to each abnormal Mini LED light-emitting panel is compared to determine whether similar abnormal data exists between different abnormal Mini LED light-emitting panels. The similar abnormal data is the abnormal data contained in at least two abnormal Mini LED light-emitting panels. The abnormal data feedback information contains multiple similar abnormal data, and each similar abnormal data is marked with the corresponding abnormal Mini LED light-emitting panel. The feedback information contains the welding point position corresponding to each similar coordinate and each similar abnormal data. By obtaining the welding point position corresponding to the similar coordinate, the specific abnormal reason can be further analyzed and recognized, and the abnormal reason is further analyzed through the working data, and the feedback information formed is fed back to the terminal device of the relevant staff, so as to help the relevant staff understand and solve the problem of the abnormal light-emitting panel, thereby the response time and processing efficiency of the relevant staff can be improved.
