Displays composed of light-emitting modules can display text, images, videos, etc., and are currently widely used in culture, media and other fields. In order to ensure the display effect of the display screen, it is necessary to position each light-emitting module in the display screen.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

First, the professional terms used in the embodiments of this application are explained:

Lens distortion: A general term for the inherent perspective distortion of optical lenses, which is the distortion caused by perspective.

Pincushion distortion: The phenomenon of the picture "shrinking" toward the center caused by the lens. Pincushion distortion is most easily noticeable when using a telephoto lens or when using the telephoto end of a zoom lens.

Barrel distortion: The barrel-shaped expansion of the imaging image caused by the physical properties of the lens in the lens and the structure of the lens group. Barrel distortion is most easily noticeable when using a wide-angle lens or when using the wide-angle end of a zoom lens.

Distortion correction: Use algorithms to correct and eliminate distortion of distorted images.

In order to eliminate errors caused by distortion correction and improve the accuracy of light-emitting module positioning, embodiments of the present application provide a light-emitting module positioning method, device, electronic equipment, storage medium and system, including:

Send a display instruction to the display screen; wherein the display instruction includes display rules and sizes of multiple target block areas in the display screen; the size of the target block area is determined based on the distortion size of the display image of the display screen obtained in advance; the display rules Including: the light-emitting module in the target block area is bright, and every two adjacent target block areas are spaced apart;

Obtain the display image when the display screen executes the display command;

Based on the image area displayed in the display image of each target block area, the light-emitting modules in each target block area are positioned to obtain the position and brightness of each light-emitting module in each target block area.

It can be seen that through the light-emitting module positioning method, device, electronic equipment, storage medium and system provided by the embodiments of the present application, the display size of the target block area can be determined according to the distortion size of the display image of the display screen obtained in advance, and the target segmentation When the light-emitting module in the block area is on and every two adjacent target block areas are spaced apart from each other, the light-emitting module in the target block area is positioned based on the acquired display image. The display size of the area is smaller. It is realized that there is no need to perform distortion correction processing on the display image, and the light-emitting module is directly positioned, thereby eliminating errors caused by the distortion correction processing and improving the accuracy of collecting the brightness and chromaticity information of the light-emitting module.

Detailed description will be given below, with reference to Figure 1. Figure 1 is a flow chart of a light-emitting module positioning method according to an embodiment of the present application;

Step S11: Send a display instruction to the display screen.

Among them, the display instructions include display rules and sizes of multiple target block areas in the display screen; the size of the target block area is determined based on the distortion size of the display image of the display screen obtained in advance; the display rules include: within the target block area The light-emitting module is bright, and every two adjacent target block areas are spaced apart.

The light-emitting module positioning method in the embodiment of the present application is applied to the controller in the display system. The display system includes a controller and a display screen. The controller can be the same device as the display screen, or it can be a different device independent of the display screen. Equipment, the above-mentioned display screen can be an LED screen, an LCD screen, or other screens with a controller controlling the light-emitting module to turn on and off. The light-emitting module can be a lamp bead in the display screen.

When the above controller is a different device independent of the display screen, the controller can send a trigger instruction to the display screen, and the display screen determines the display rules and sizes of multiple target block areas based on the received trigger instructions.

The size of the target block area is determined based on the distortion size of the display image of the display screen obtained in advance, which can be obtained based on experience. For example, first obtain a display image of the display screen through the image acquisition device. When the display screen displays When the distortion of the image is small and can be ignored, the entire display area of the display screen can be divided into a block area. When the distortion of the display image of the display screen is large, the size of the target block area can be set to a smaller size. , such as 3×3 light-emitting modules, 5×5 light-emitting modules, etc. When the distortion of the display image on the display screen is moderate, the size of the target block area can be set to: 20×20 light-emitting modules, 50×50 light-emitting modules, etc. Assume that the maximum number of light-emitting modules of the current LED screen is W*H and the number of screen blocks is n*m; then the size of each block is W/n*H/m. When m=n=1, the displayed block area The size of is the size of the entire screen. When m=1&n=2 or n=1&m=2, each block area is half of the entire screen. In this embodiment of the present application, the shape of each target block area may be a rectangle, a square, or other shapes. Since the colors of the light-emitting modules can correspond to different colors such as red, green, blue, and white, when the light-emitting modules in the target block area are on, the light-emitting modules in multiple target block areas can all be of the same color. Each two adjacent target block areas are spaced apart. One or more groups of light-emitting modules can be spaced between each two adjacent target block areas, so that the two adjacent target block areas are not connected. When the display image is collected from the area where the light-emitting module lights up in the display screen, the size of each area is determined based on the distortion size of the display image of the display screen obtained in advance. When the light-emitting modules in the target block area are on, the light-emitting modules in the remaining areas of the display screen may not be on.

Step S12: Obtain the display image when the display screen executes the display instruction.

Among them, the display image when the display screen executes the display instruction can be obtained through an image acquisition device, such as a camera, to collect the display image when the display screen executes the display instruction, or the display image obtained by screenshots or other methods when the display screen executes the display instruction. image.

Step S13: Based on the image area in the display image displayed in each target block area, the light-emitting modules in each target block area are positioned to obtain the position and brightness of each light-emitting module in each target block area.

Among them, based on the image area displayed in the display image of each target block area, the light-emitting module in each target block area is positioned. The light-emitting module in each target block area can be positioned by methods such as projection method and coordinate method. To position. For example, the image area displayed in the display image is discretized according to the brightness of the light-emitting module, and the center point of each light-emitting module is determined. By determining the connection of the center points of the light-emitting modules whose center points are on the same horizontal line and vertical line, The intersection point of the lines is used to obtain the position of each light-emitting module. Then, the brightness and chromaticity of each light-emitting module is collected according to the position of each light-emitting module, and the brightness and chromaticity of each light-emitting module in each target block area is obtained.

It can be seen that through the light-emitting module positioning method provided by the embodiment of the present application, the display size of the target block area can be determined according to the distortion size of the display image of the display screen obtained in advance. The light-emitting module in the target block area is bright and every two When there are target block areas distributed at intervals between adjacent target block areas, the light-emitting module in the target block area is positioned according to the obtained display image of the display screen. Since the display size of the target block area is small, no need to Perform distortion correction processing on the display image and directly position the light-emitting module, thereby eliminating errors caused by the distortion correction processing and improving the accuracy of collecting brightness and chromaticity information of the light-emitting module.

Optionally, referring to Figure 2, in step S13, the light-emitting modules in each target sub-area are positioned based on the image area in the display image displayed in each target sub-area to obtain each light-emitting module in each target sub-area. Before the position and brightness steps, the above method also includes:

Step S14: Determine the position of the image area in the display image displayed in each target block area.

Determining the position of each target block area in the image area displayed in the display image can be achieved in a variety of ways. For example, after obtaining the display image when the display screen executes the display instruction, according to the theory of digital graphics morphology, using rectangular two The dimensional matrix expands each light-emitting module area, and the pixel features corresponding to the light-emitting module in the collected image are expanded by N pixels in the vertical and horizontal directions to expand the pixel features corresponding to each light-emitting module, where N is equal to two phases. More than half the distance between adjacent light-emitting modules. Through the expansion process, the pixel features corresponding to the light-emitting modules in the block area can be merged, so that each block area can be regarded as a "large light-emitting module", and then the light-emitting module positioning algorithm is used to determine the display image of each target block area. The location of the image area displayed in .

Step S15: Arrange the image areas according to their positions to obtain an arrangement chart.

Wherein, arranging each image area according to the position of each image area may be to obtain the display image when the display screen executes the display instruction, and then extract the image area of each target block area displayed in the display image from the display image, The extracted image areas are then arranged according to the position of each image area to obtain an arrangement chart. Arrange the extracted image areas according to the position of each image area to obtain an arrangement chart. You can arrange each image area according to the relative position of each image area to obtain an arrangement chart. For example, in the display screen, block area 1 is located at To the left of block area 2, in the generated arrangement chart, 1 is still located to the left of 2. When generating an arrangement chart, the arrangement chart can be obtained by splicing or simply arranging in the corresponding order. For example, in the display screen, block area 1 is not adjacent to block area 2, that is, block area 1 is not adjacent to block area 2. There are other light-emitting modules between 2, but when determining the position of the image area in the display image displayed in each target block area this time, the position of the block area between block area 1 and block area 2 was not obtained. Therefore, when generating a permutation chart, you can splice 1 and 2 together to get a permutation chart, or just arrange 1 and 2 in order to get a permutation chart containing 1 and 2.

For example, see Figure 3a, the image areas where the values 1, 2, 3, and 4 are located respectively correspond to different image areas. When a certain display instruction is executed, the light-emitting module in the image area corresponding to each number lights up. For example, when a certain display instruction is executed, When a display command is executed, the light-emitting module in the image area corresponding to value 1 lights up, and when another display command is executed, the light-emitting module in the image area corresponding to value 2 lights up. When arranging according to the position of the image area corresponding to 1 in the figure, the image area corresponding to 1 can be arranged according to the relative position in the displayed image. For example, in the order from top to bottom, from left to right, determine the upper left in the figure. The position of the image area corresponding to 1 in the corner is (0, 0), and the position of the image area corresponding to 1 in the lower right corner is (1, 1). Then, each image area is arranged according to the position of each image area, and an arrangement diagram can be obtained as shown in Figure 3b.

Step S16: Update the display rules of each target block area, obtain updated display instructions, and send the updated display instructions to the display screen.

Among them, the target block area after the display rule is updated is the adjacent area of the target block area before the display rule is updated, and the adjacent area of the target block area is the target block area among multiple block areas in the display screen. One of the neighboring tiles. When the color of the light-emitting module includes multiple colors, the color of the light-emitting module corresponding to the updated display instruction may be the same as the color of the light-emitting module before the update. The size of the multiple target subdivision areas in the display screen corresponding to the updated display instruction may be the same as before the update. And every two adjacent target block areas of the updated display instructions are distributed at intervals.

Step S17: Obtain the display image of the display screen that executes the updated display instruction, and return to the step of determining the position of the image area in the display image displayed in each target block area until the entire display screen is traversed and multiple arrangement charts are obtained.

The arrangement chart is an arrangement chart obtained by arranging each image area according to the position of each image area. Traversing the entire display screen, multiple arrangement diagrams can be obtained by updating multiple times and sending updated display instructions to the display screen. The multiple arrangement diagrams can include image areas corresponding to all light-emitting modules in the display screen.

Step S13 is a step of positioning the light-emitting modules in each target block area based on the image area in the display image displayed in each target block area, and obtaining the position and brightness of each light-emitting module in each target block area, including:

Step S131: Reorganize each arrangement chart according to the position of each block area in the display screen to obtain a reorganized display image.

Each arrangement diagram includes a plurality of image blocks corresponding to image areas in the display image. For any image block in the reorganized display image, the position of the image block in the reorganized display image is consistent with the image. The image areas corresponding to the blocks have the same position in the displayed image. According to the arrangement order of the block areas on the display screen, each arrangement chart is reorganized. This may be to rearrange the image blocks in each arrangement chart according to the display instructions. cloth. The image blocks in the arrangement chart may be the same as the image areas in the display image. For example, in the display screen, the block area 1 is not adjacent to the block area 2, that is, there are no other light-emitting modules between the block area 1 and the block area 2. However, each target block area is determined this time. When the position of the image area in the displayed image is displayed, the position of the block area between 1 and 2 is not obtained. Therefore, when generating the arrangement chart, 1 and 2 can be spliced together to obtain the arrangement chart, and according to the display screen Arrangement order of block areas, reorganize each arrangement chart, and obtain the reorganized display image. After obtaining the block areas between 1 and 2, correspond to the original block areas 1 and 2, and obtain the arrangement chart. of image blocks 1 and 2, where block area 1 is the same as image block 1, block area 2 is the same as image block 2, and then, according to image block 1, image block, image block between Reorganize in the order of 2 to obtain the reorganized display image. For example, according to the display command, it can be known that the block area corresponding to 1 is to the left of the block area corresponding to 2, the block area corresponding to 3 is below the block area corresponding to 1, and the block area corresponding to 4 is to the block area corresponding to 2. Therefore, according to the arrangement order of the above-mentioned block areas, each image in the arrangement diagram can be block-reorganized to obtain a reorganized display image. For example, refer to each arrangement diagram in Figure 4a and perform reorganization to obtain the reorganized display image Figure 4b.

Step S132: Position each light-emitting module in the reorganized display image to obtain the position and brightness of each light-emitting module.

In the reorganized display image, each light-emitting module can be positioned using a variety of methods. For example, the position and brightness of each light-emitting module can be obtained through projection method, coordinate method, and other methods.

Since the reorganized display image is reorganized from the arrangement of the block areas in the display screen, the reorganized display image is obtained. The size of the block area is determined based on the distortion of the pre-acquired display image of the display screen. Therefore, if the distortion is small, the light-emitting module can be positioned directly without performing distortion correction on the reorganized display image. Therefore, errors due to distortion correction will not occur.

Optionally, referring to Figure 5, step S14 determines the position of the image area in the display image displayed in each target block area, including:

Step S141: Perform pixel expansion processing on the image area in the display image displayed in any target block area to obtain the corresponding luminous point of the target block area in the display image.

For example, according to the theory of digital graphics morphology, a rectangular two-dimensional matrix is used to expand each light-emitting module area. The pixel features corresponding to the light-emitting modules in the collected image are expanded by N pixels in the vertical and horizontal directions to perform expansion processing on the pixel features corresponding to each light-emitting module, where N is equal to more than half of the distance between two adjacent light-emitting modules. The expansion process can ensure that the images of adjacent light-emitting modules in the block area are connected together, and the pixel features corresponding to the light-emitting modules in the block area are merged, so that each block area can be regarded as a "large light-emitting module". The light-emitting point is the "large light-emitting module", and there are no other light-emitting modules between the adjacent areas.

Step S142: Based on the corresponding light-emitting points of each target block area in the display image, use the light-emitting module positioning algorithm to determine the position of each target block area in the image area displayed in the display image.

By treating the above-mentioned block area as a "large light-emitting module" and using the light-emitting module positioning algorithm, the position of each target block area in the image area displayed in the display image can be directly determined.

Optionally, step S141 performs pixel expansion processing on the image area in the display image displayed in any target block area to obtain the corresponding luminous point of the target block area in the display image, including:

For the image area in the display image displayed in any target block area, expand N pixels in the vertical and horizontal directions of the image area to obtain the corresponding luminous point of the target block area in the display image, where N is greater than Half of the preset distance between two adjacent light-emitting modules, and there are no other light-emitting modules between the adjacent light-emitting modules.

Optionally, referring to Figure 6, step S13 locates the light-emitting modules in each target block area based on the image area in the display image displayed in each target block area, and obtains the position of each light-emitting module in each target block area. and brightening steps, including:

Step S133: For any target block area, determine the position of each light-emitting module in the target block area according to the size of the target block area in the display instruction.

Among them, according to the size of the target block area in the display instruction, the position of each light-emitting module in the target block area is determined. For example, for a certain display instruction, the size of the target block area is 3×3, that is, the target block area The arrangement rule of the light-emitting modules in is 3×3, so when the target block area is determined, the center of the block area can be considered to be the center of the 3×3 arranged light-emitting module area, thereby determining the target block area. The location of each light-emitting module.

Step S134: Arrange the light-emitting modules in the target block area to obtain the light-emitting module arrangement matrix corresponding to the target block area.

Step S135: Determine the non-compensated light-emitting modules in the light-emitting module arrangement matrix according to the size of the preset compensation area.

The non-compensated light-emitting modules are light-emitting modules in areas other than the preset compensation area in the target block area.

Because under normal circumstances, the brightness of the light-emitting module will be affected by the brightness of the light-emitting modules in adjacent areas. Therefore, in order to ensure that the brightness and chromaticity values of the light-emitting modules that need to be collected in each area are the same as the actual ones, it is necessary to light up the light-emitting modules in several rows (p rows) adjacent to the area as supplementary areas for compensation. There is no other light-emitting area between the adjacent areas. module. For example, for an n*n block area, the size of the corresponding light-emitting module arrangement matrix is (n+2*p)*(n+2*p). When the block area is located at the edge of the screen, p does not need to be performed. Make compensation. For example, see Figure 7. The target block area is the 3×3 light-emitting module area in the dotted box in the figure. After compensating for one line, the area where the light-emitting module lights up when the display command is executed is a 5×5 light-emitting module area.

When performing compensation, the display instruction may include the compensation area. For example, when positioning the light-emitting module in a 3×3 light-emitting module area, the controller sends a display instruction to the display screen to display a 5×5 area including the compensation area. The light-emitting module area can also be a light-emitting module area that only contains 3×3 when the controller sends a display instruction to the display. According to the display instruction and the compensation strategy, the display finally displays a 5×5 area including the compensation area. Light module area.

For example, for an n*n block area, the compensation rule is to perform p row compensation, and the corresponding light-emitting module arrangement matrix is obtained as (n+2*p)*(n+2*p), so that the p light-emitting module can be Arrangement rules determine the position of the non-compensated light-emitting module n*n in the light-emitting module arrangement matrix (n+2*p)*(n+2*p).

Step S136: Taking the position of each non-compensated light-emitting module as the center, calculate the average pixel value of each pixel point within the preset radius range of the target block area in the image area displayed in the display image, and obtain each non-compensated light-emitting module. The brightness of the module.

After determining the non-compensated light-emitting modules in the light-emitting module arrangement matrix, taking the position of each non-compensated light-emitting module as the center, calculate the pixel value of each pixel within the preset radius range of the image area displayed in the display image of the target block area. The pixel value can be used to obtain the brightness and chromaticity of each light-emitting module in the target block area.

Optionally, referring to Figure 8, in step S13, based on the image area in the display image displayed in each target block area, the light-emitting modules in each target block area are positioned to obtain the values of each light-emitting module in each target block area. After the position and brightness steps, the above method also includes:

Step S18: Determine the area to be corrected in the display screen.

The area to be corrected in the display screen may be the display area of the entire display screen, or may be a certain part of the display screen. When the area to be corrected is a certain part of the display screen. Based on the image area displayed in the display image of each target block area, positioning the light-emitting module in each target block area may be based on only the image area after obtaining only the image area displayed in the display image of the display area. For positioning the light-emitting module in the area to be corrected, it is not necessary to obtain the display image of the remaining areas in the display screen and position the light-emitting module. Therefore, when the size of the area to be corrected is small, the time required for positioning the light-emitting module can be saved.

Step S19: Obtain the brightness chromaticity of each light-emitting module in the area to be corrected under different solid color display conditions.

When the colors displayed by the light-emitting modules include multiple colors, the brightness chromaticity of each light-emitting module in the area to be corrected under different pure color display conditions can be obtained separately. For example, the brightness of each light-emitting module in the area to be corrected under different pure color display conditions can be obtained separately. For example, the brightness of red, green, and blue colors to be corrected can be obtained separately. The brightness of the area's light-emitting module.

Step S20: Calculate the average brightness and chromaticity of each light-emitting module in the area to be corrected.

To calculate the average brightness and chromaticity of each light-emitting module in the area to be corrected, the average brightness and chromaticity of each light-emitting module in the area to be corrected can be calculated based on the obtained brightness and chromaticity of all the light-emitting modules in the area to be corrected, thereby obtaining the average brightness and chromaticity of each light-emitting module in the area to be corrected.

Step S21: Calculate the difference between the brightness and chromaticity of each light-emitting module in the area to be corrected and the average brightness and chromaticity, and perform brightness and chromaticity correction on the light-emitting modules whose difference value is greater than the preset threshold.

Calculate the difference between the brightness and chromaticity of each light-emitting module in the area to be corrected and the average brightness and chromaticity. The obtained brightness and chromaticity and the average brightness and chromaticity of each light-emitting module in the area to be corrected can be compared. The brightness and chromaticity of each light-emitting module and When the difference between the average brightness and chromaticity values is greater than the preset threshold, it is considered that the brightness and chromaticity of the light-emitting module affects the display effect of the display screen, and brightness and chromaticity correction is performed. The preset threshold can be an artificially set value.
