Description

Technical Field

[0001] This application relates to the field of LED display technology, and in particular to a method, apparatus, equipment and medium for detecting the correctness of spot sampling on a lamp board. Background Technology

[0002] With the increasing demand for creative displays, LED displays are no longer limited to traditional rectangular or square shapes. Now, LED displays can be customized into various irregular shapes, such as circles, arcs, and waves, to suit different installation environments and design requirements. Therefore, irregularly shaped LED screens have emerged. Irregularly shaped LED screens are generally composed of multiple irregularly shaped LED panels. To illuminate these panels, before lighting, it's usually necessary to perform a point-sampling operation (removing certain LEDs from the regular panels) in the control software to create panels corresponding to the physical irregularly shaped panels. In point-to-point displays, errors in the point-sampling operation can lead to distorted image display on the screen.

[0003] In related technologies, the LED light board is checked for correct sampling by manual re-inspection. However, this method requires manual inspection of each light point, which is very time-consuming and inefficient, especially when there are many light boards or dense light points.

[0076] The technical solution provided in this application has the following advantages compared with the prior art:

[0077] This application provides a method for detecting the correctness of light panel spot selection. In response to a user's setting of the dot matrix density, a predicted light spot distribution map of the object to be tested is generated. The predicted light spot distribution map represents the light spot distribution map of the object to be tested after the preset dot matrix density is set to be illuminated at intervals. The object to be tested includes at least one irregularly shaped light panel obtained by performing spot selection on a rectangular light panel. The object to be tested is controlled to display at intervals according to the preset dot matrix density to obtain the actual light spot display distribution map of the object to be tested. Based on the actual light spot display distribution map and the predicted light spot distribution map of the object to be tested, the correctness of the spot selection operation on the object to be tested is determined. Since the object to be inspected refers to at least one physically irregularly shaped light panel, and the virtual irregularly shaped light panel corresponding to each physically irregularly shaped light panel is a virtual irregularly shaped light panel obtained by sampling points from a virtual rectangular light panel, the software generates an expected light point distribution map corresponding to the object to be inspected based on the preset dot matrix density set by the user. This provides a benchmark for subsequent sampling point inspection. The software further controls the object to be inspected to display points at intervals according to the preset dot matrix density to obtain an actual light point display distribution map. By comparing the expected and actual light point distribution maps, the correctness of the sampling point operation can be evaluated. This method of automatically controlling the light points on the irregularly shaped light panel to display points at intervals simplifies the operation process. After sampling points on the light panel, it improves the efficiency of detecting whether there are errors in the sampling points, which helps to improve product quality, reduce rework and scrap rates, thereby reducing costs and improving production efficiency.

[0088] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0089] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0090] Traditional LED displays are primarily used to display fixed images. With technological advancements, LED displays can now support mobile displays, meaning they can be designed as movable structures for different scenarios. Simultaneously, with increasing demands for creative displays, LED displays are no longer limited to traditional rectangular or square shapes. They can now be customized into various irregular shapes, such as circles, arcs, and waves, to adapt to different installation environments and design requirements, thus giving rise to irregularly shaped LED screens. Irregularly shaped LED screens generally consist of multiple irregularly shaped LED panels. To illuminate these panels, before activation, the control software typically needs to perform a point-sampling operation (removing certain LEDs from the standard panels) to create panels corresponding to the physical irregularly shaped panels. Incorrect point-sampling can lead to distorted image display on the screen. For example, when displaying a customized video source point-to-point, inaccurate point-sampling will result in a mismatch between the number of LEDs in the video source and the display screen, leading to poor display quality. In addition, when calibrating the display screen, if the number of sampled LEDs does not match the actual number of physical LEDs, the calibration coefficients may not correspond one-to-one with the actual LEDs, resulting in poor calibration results.

[0091] In related technologies, the LED light board is checked for correct sampling by manual re-inspection. However, this method requires manual inspection of each light point, which is very time-consuming and inefficient, especially when there are many light boards or dense light points.

[0092] Therefore, how to quickly detect whether there are errors in the spotting operation of the lamp board before display or calibration is an urgent problem to be solved.

[0093] In one embodiment, such as Figure 1 As shown, a method for detecting the correctness of light panel sampling is provided. This method can be applied in display control systems, as described above. Figure 2A As shown, Figure 2A This is a schematic diagram of the display control system, which includes: a terminal device 21, a transmitting card 22, and an LED display screen 23. The terminal device 21 is a user-operated device, such as a computer or control panel. The terminal device 21 contains control software that can be used to set display parameters, execute detection programs, etc. The transmitting card 22 connects the terminal device 21 and the LED display screen 23, and is responsible for receiving instructions and data from the control software and sending them to multiple receiving cards on the display screen 23. Figure 2A (The following is an illustration using receiver cards 1, 2, 3, ..., 10 as examples.) It can be understood that the functions of terminal device 21 and sending card 22 can be integrated into the same device. In this embodiment, the terminal device and sending card are not integrated into the same device. LED display screen 23 includes multiple cabinets, each containing an embedded receiver card. When at least one receiver card receives instructions or data sent by the sending card, it parses or processes the instructions or data and performs corresponding operations. The LED display screen receives control signals, drives the LED dots through the receiver cards, and ultimately displays the image. This display control system can verify the correctness of the LED panel's dot sampling operation through a detection program (such as a dot plotting diagram) in the control software, thereby ensuring display quality or correction effect. Furthermore, it should be noted that this method is also applicable to the correctness detection of LED panel dot cutting.

[0094] like Figure 1 As shown in this embodiment of the disclosure, the method includes the following steps:

[0095] S11. In response to the user's setting operation on the dot matrix density, generate the expected light distribution map of the object to be detected.

[0096] The expected light distribution map is used to represent the light distribution map after the object to be detected is set to be lit at intervals based on the preset dot matrix density set by the user; the object to be detected includes at least one irregularly shaped light panel obtained by performing a spotting operation on a rectangular light panel.

[0097] It should be noted that the object to be tested refers to the physical display screen, which includes at least one physical irregularly shaped light panel. The rectangular light panel is a virtual rectangular light panel in the control software. The sampling operation refers to the user sampling points on the virtual rectangular light panel in the control software to obtain the virtual irregularly shaped light panel. It can be understood that the virtual irregularly shaped light panel corresponds to the physical irregularly shaped light panel.

[0098] Since the display screen is composed of multiple cabinets, and each cabinet is composed of multiple light panels, the object to be tested can be a light panel, a cabinet, or a display screen. That is, the object to be tested includes irregularly shaped light panels, irregularly shaped cabinets, or virtual irregularly shaped LED displays obtained by sampling rectangular light panels, rectangular cabinets, or rectangular LED displays.

[0099] In LED displays, the dot matrix density determines the level of detail that the display can show. High-density displays are suitable for close-range viewing, such as indoor advertising screens and stage background screens; while low-density displays are suitable for long-distance viewing, such as large outdoor advertising screens and stadium displays.

[0100] In this embodiment of the disclosure, the preset dot density of the dot matrix diagram (i.e., the expected distribution of light points) can be set according to the actual application scenario. For example, the preset dot matrix density can be set to 2×2, 3×4, or other reasonable values, without specific limitations. For example, if the preset dot matrix density of the dot matrix diagram is set to 2×2, it means that every other dot in each row is lit; and every other dot in each column is lit. That is, in each row, solid dots will be lit at certain intervals, while other positions remain dark. If the preset dot matrix density of the dot matrix diagram is set to 3×4, it means that every two dots in each row are lit; and every three dots in each column are lit. For example, refer to... Figure 2B As shown, the control software's interface has an option to select the dot matrix density. Assuming the preset dot matrix density is 2×2, when the object to be detected is a target light panel, the target light panel is controlled to display dots at intervals according to the user-set preset dot matrix density of 2×2, thus obtaining the expected light dot distribution map corresponding to the target light panel.

[0101] Specifically, the object to be tested includes at least one irregularly shaped light panel obtained by sampling points from a rectangular light panel, for example, a virtual irregularly shaped light panel obtained by sampling points from a virtual rectangular light panel. Since an LED cabinet is composed of at least one light panel, and an LED display screen is composed of at least one LED cabinet, the user can select the object to be tested as a virtual irregularly shaped light panel, a virtual irregularly shaped cabinet, or a virtual irregularly shaped LED display screen on the control software's interface. In response to the user's setting of the dot matrix density on the control software's interface, a projected dot distribution map of the object to be tested is generated. This projected dot distribution map is used for comparison with the actual dot display distribution map of the object to be tested.

[0102] In some embodiments, before performing step S11 (generating the expected light distribution map of the object to be detected in response to the user's setting operation on the dot matrix density), the following steps may also be performed:

[0103] 1) In response to the user's sampling operation on the rectangular light panel, obtain the virtual and real point information corresponding to the irregular light panel.

[0104] The virtual and real point information includes the number and position of virtual and real points on the rectangular light panel.

[0105] In this embodiment of the disclosure, the sampling operation refers to the user selectively removing or not installing certain LED beads on a virtual rectangular light board according to specific user needs or designs on the terminal control software, so as to form a non-rectangular (i.e. irregular) light board that corresponds to the physical irregular light board.

[0106] Specifically, based on the final design shape and size of the LED display screen, i.e., the virtual and real point information corresponding to the irregularly shaped light panel, including the number and position of virtual and real points on the rectangular light panel, certain light points in the virtual rectangular light panel in the control software are sampled to adapt to a specific display area. In response to the user's sampling operation on the rectangular light panel, the virtual and real point information of the irregularly shaped light panel is obtained. Virtual and real point information refers to the number and position of virtual and real points on the rectangular light panel corresponding to the irregularly shaped light panel after the sampling operation in the control software. Virtual points refer to positions that are skipped in the design and do not require LED chips, while real points are the actual positions where LED chips need to be installed. The specific position of each real point is usually represented by coordinates, such as coordinate values ​​in an (x,y) coordinate system.

[0107] 2) In response to the user's configuration operation on the at least one irregularly shaped light panel, obtain the enclosure configuration information of at least one irregularly shaped enclosure.

[0108] The enclosure configuration information includes virtual and real point information, position information, and connection method information corresponding to at least one irregularly shaped light panel constituting the irregularly shaped enclosure. Virtual and real point information refers to the number and position of virtual and real points on the rectangular light panel corresponding to the irregularly shaped light panel after point sampling operation on the control software. Position information refers to the specific position of each irregularly shaped light panel within the enclosure, including the three-dimensional coordinates of the light panel and its position relative to the edge of the enclosure or other light panels. Connection method information refers to the electrical connection method between the various irregularly shaped light panels, including series and parallel connections, as well as physical connection methods such as screw fixing and snap-fit ​​connection.

[0109] Specifically, after sampling all rectangular light panels, the wiring of all modules inside a single cabinet needs to be done in the control software, and the positional relationship of the modules after sampling needs to be set in a single cabinet.

[0110] 3) In response to the user's configuration operation on the at least one irregularly shaped box, obtain the screen configuration information of the irregularly shaped screen.

[0111] The screen configuration information includes the physical connection order between the various irregularly shaped boxes that constitute the irregularly shaped screen.

[0112] Specifically, to enable the display screen to show specific shapes according to user needs, the user needs to configure the virtual LED irregular-shaped display screen on the control software interface. An irregular-shaped screen refers to a display screen created through software configuration and cabinet wiring information, which can simulate an actual physical display screen. When assembling the irregular-shaped screen, the physical connection of the cabinet must be guided according to the screen configuration information to ensure the correctness of the display.

[0113] 4) In response to the user's information delivery operation, the virtual and real location information, the box configuration information, and the screen configuration information are sent to the sending card.

[0114] Specifically, users execute a distribution operation through the control software's interface. The purpose of this operation is to transmit the user's configuration intentions (such as virtual and physical point information, cabinet configuration information, and screen configuration information) to the sending card in the display control system, enabling the sending card to correctly control the display screen based on this information. When setting up an LED display screen, the distribution operation sends configuration information to the sending card, thereby controlling the display screen's display effect.

[0115] Optionally, after performing step 4) above, it can also be achieved in the following way:

[0116] In response to the user's driving operation on the irregularly shaped screen, the terminal device sends the virtual and real point information, the cabinet configuration information, the screen configuration information, and the point data table to the receiving card through the sending card, so that the receiving card sequentially drives the light points of at least one irregularly shaped cabinet to display the corresponding pixels according to the virtual and real point information, the cabinet configuration information, the screen configuration information, and the point data table.

[0117] The point data table includes the mapping relationship between each light point in each cabinet and the actual video source pixel. This mapping relationship ensures that the content of the video source can be correctly mapped to each point on the display screen. The control software sends the point data table to the receiving card via a sending card. The sending card acts as a bridge between the control software and the display screen, responsible for transmitting the point data table to the receiving card of the display screen. The sending card can exchange data with the receiving card via a network, serial communication, or other communication interfaces.

[0118] Specifically, after receiving the virtual and real point information, cabinet configuration information, screen configuration information and point data table sent by the sending card, the receiving card, based on the point data table and the virtual and real point information, cabinet configuration information and screen configuration information, sequentially drives the light points of at least one cabinet to display the corresponding pixels, and controls the cabinet or light board connected to it to display images and video content in a predetermined manner.

[0119] In some embodiments, before performing step S12 (controlling the object to be detected to display at intervals according to the preset dot matrix density to obtain the actual light dot display distribution map of the object to be detected), the following steps may also be performed:

[0120] In response to the user's sampling operation on the rectangular light panel, the virtual and real point information of the object to be detected is obtained.

[0121] The virtual and real point information includes the number and position of virtual and real points on the at least one rectangular light panel. It should be noted that the rectangular light panel is a virtual rectangular light panel used in the control software for point sampling operations. Therefore, obtaining the number and position of virtual and real points on at least one rectangular light panel facilitates the determination of the real point coordinates of the object to be detected.

[0122] The coordinates of the real points of the object to be detected are determined based on the virtual and real point information.

[0123] Specifically, before controlling the object to be tested to display at intervals according to a preset dot matrix density to obtain a lamp display distribution map, the control software acquires the number and position of virtual and solid points on at least one rectangular lamp panel. Based on the acquired virtual and solid point position information, the coordinate position of each solid point is determined. Obtaining the coordinate position of the solid points of the object to be tested facilitates subsequent control of the object to be tested to display at intervals according to the preset dot matrix density, thereby obtaining an actual lamp display distribution map of the object to be tested.

[0124] S12. Control the object to be detected to display at intervals according to the preset dot matrix density, so as to obtain the actual light dot display distribution map of the object to be detected.

[0125] In some embodiments, step S12 (controlling the object to be detected to display at intervals according to the preset dot matrix density to obtain the actual light dot display distribution map of the object to be detected) can be implemented in the following way:

[0126] (1) Generate the expected lamp distribution map based on the preset dot matrix density and the coordinate position of the real points;

[0127] (2) Drive the object to be detected to display according to the expected light distribution map to obtain the actual light display distribution map.

[0128] Specifically, generating the expected LED dot distribution map is to obtain a theoretical display effect diagram. This diagram, based on the user-defined dot matrix density and real dot coordinate positions, reflects the ideal LED dot distribution that the LED display should have. By driving the LED display (the object under test) using the expected dot distribution map and making it display, an actual dot display distribution map can be obtained. This actual dot display distribution map reflects the display's performance under actual operating conditions. That is, according to the expected dot distribution map, the terminal equipment in the display control system sends signals to each LED on the display via a sending card, turning the LEDs on or off according to the instructions in the expected dot distribution map, and adjusting the color and brightness. During the production process, by comparing the expected dot distribution map and the actual dot display distribution map, manufacturing defects in the display can be detected, such as missing LEDs, uneven brightness, or color deviation.

[0129] It should be noted that there are three ways to generate the expected light distribution map data: it can be generated on the terminal device (control software), on the sending card, or on the receiving card. The specific device chosen for generating the expected light distribution map data depends on the actual application scenario. Because the methods for generating the expected light distribution map data differ, the methods for controlling the object to be detected to display dots at preset dot density to obtain the actual light distribution map of the object to be detected also differ. These three scenarios will be explained in detail below.

[0130] Reference Figure 2A As shown, Figure 2A This is a schematic diagram of the display control system. The system includes terminal devices, sending cards, and receiving cards connected in sequence, with the receiving cards connected to the object to be detected. The terminal device 21 is a user-operated device, such as a computer or control panel. Control software is installed in the terminal device 21, which can be used to set display parameters and execute detection programs. The sending card 22 connects the terminal device 21 and the LED display screen 23, and is responsible for receiving instructions and data from the control software and sending them to multiple receiving cards on the display screen 23. Figure 2A (Taking receiving card 1, receiving card 2, receiving card 3, ..., receiving card 10 as examples for illustration) In this example, the receiving card is a device that is directly connected to the object to be tested (such as the irregularly shaped light panel or irregularly shaped box of the LED display screen). It is responsible for receiving the data transmitted by the sending card and controlling the LED beads on the display screen to light up according to the expected LED distribution pattern.

[0131] Optionally, for the first scenario described above, i.e., generating the expected light distribution map data on the terminal device (control software), the above step (1) (generating the expected light distribution map based on the preset dot matrix density and the real point coordinate positions) can be implemented as follows: the terminal device generates the expected light distribution map data based on the preset dot matrix density and the real point coordinate positions.

[0132] The above step (2) (driving the object to be detected to display according to the expected light distribution map to obtain the actual light display distribution map) can be implemented in the following way: the terminal device sends the expected light distribution map data to the sending card, so that the sending card renders the expected light distribution map according to the expected light distribution map data, and sends the rendered expected light distribution map to the receiving card, so that the receiving card drives the display according to the rendered expected light distribution map to obtain the actual light display distribution map.

[0133] In this embodiment of the disclosure, the expected light distribution map data is generated on the terminal device (control software). Specifically, the terminal device generates the expected light distribution map data based on the preset dot matrix density and the coordinate positions of the real points. Then, the generated expected light distribution map data is sent to the sending card. After receiving the expected light distribution map data, the sending card performs rendering processing, that is, it converts the expected light distribution map data into a format that the display screen can recognize and execute. Then, the sending card sends the rendered expected light distribution map to the receiving card. The receiving card controls the LEDs on the object to be detected to light up according to the received rendered expected light distribution map, thereby displaying the actual light distribution map on the display screen.

[0134] Optionally, for the second scenario described above, i.e., generating the expected light distribution map data on the sending card, the above step (1) (generating the expected light distribution map based on the preset dot matrix density and the real point coordinate positions) can be implemented as follows: the terminal device sends the real point coordinate positions and the preset dot matrix density to the sending card, so that the sending card generates the expected light distribution map data based on the real point coordinate positions and the preset dot matrix density.

[0135] Step (2) above (driving the object to be detected to display according to the expected light distribution map to obtain the actual light display distribution map) can be achieved in the following way:

[0136] The sending card renders the expected light distribution map data and sends the rendered expected light distribution map to the receiving card, so that the receiving card can drive the display according to the rendered expected light distribution map to obtain the actual light display distribution map.

[0137] In this embodiment, the generation of the expected light distribution map data is implemented on the transmitting card. Specifically, the terminal device sends the real point coordinates and a preset dot matrix density to the transmitting card, and the transmitting card generates the expected light distribution map data based on the received real point coordinates and preset dot matrix density. Then, the transmitting card renders the expected light distribution map data and sends the rendered expected light distribution map to the receiving card, so that the receiving card can drive the display based on the rendered expected light distribution map to obtain the actual light display distribution map.

[0138] Optionally, for the third scenario described above, i.e., generating the expected light distribution map data on the receiving card, the above step (1) (generating the expected light distribution map based on the preset dot matrix density and the real point coordinate positions) can be implemented as follows: the terminal device sends the real point coordinate positions and the preset dot matrix density to multiple receiving cards through the sending card, so that each receiving card generates the expected light distribution map data for its respective driving section.

[0139] Step (2) above (driving the object to be detected to display according to the expected light distribution map to obtain the actual light display distribution map) can be achieved in the following way:

[0140] Each of the receiving cards drives the display according to the expected distribution map data of each light point, so as to obtain the actual light point display distribution map.

[0141] In this embodiment, the expected light distribution map data is generated on the receiving card. The sending card has multiple network ports. That is, the terminal device sends the real point coordinates and preset dot density to the multiple receiving cards through the multiple network ports of the sending card, so that each receiving card generates the expected light distribution map data for its respective driving part. Then, each receiving card renders according to the expected light distribution map data, and drives the display of the rendered expected light distribution map to obtain the light display distribution map.

[0142] S13. Based on the actual light distribution map of the object to be tested and the expected light distribution map, determine the correctness of the sampling operation on the object to be tested.

[0143] Optionally, step S13 (determining the correctness of the sampling operation on the object to be tested based on the actual light distribution map and the expected light distribution map of the object to be tested) can be implemented in the following way:

[0144] Determine whether the actual light distribution map of the object to be detected matches the expected light distribution map. Figure 1 If the actual light distribution map of the object to be detected differs from the expected light distribution... Figure 1 If the actual light distribution map of the object to be tested is inconsistent with the expected light distribution map, it is determined that the sampling operation of the object to be tested is incorrect.

[0145] Specifically, the actual distribution of the lights on the object under test is determined by observation to see if it matches the expected distribution. Figure 1 Alternatively, an image capture device can be used to obtain a map of the actual distribution of LEDs on the display screen. This allows for subsequent image processing to determine whether the actual distribution of LEDs on the object being detected matches the expected distribution. Figure 1 If the actual distribution of the lights on the object to be tested differs from the expected distribution... Figure 1 If the actual light distribution of the object under test differs from the expected light distribution, the sampling operation for the object under test is deemed incorrect.

[0146] For example, refer to Figure 2C As shown, Figure 2C The left side shows the original light dot layout of a virtual irregular light panel obtained after performing a dot sampling operation on a virtual rectangular light panel. It is assumed that the user-set preset dot density is 2×2. Figure 2C The right side shows the expected distribution of light points obtained by processing the original light point layout according to the preset dot matrix density and displaying the dots at intervals.

[0147] Reference Figure 2D As shown, Figure 2DThe left side shows the original light dot layout of the object to be tested (physical irregular-shaped light board) corresponding to the aforementioned virtual irregular-shaped light board. Assume that the user-set preset dot density is 2×2. Figure 2D The right side shows the actual distribution of light points displayed according to the preset dot matrix density for the object to be detected. Figure 1 ,because Figure 2D The actual distribution of light points on the right side Figure 1 and Figure 2C Expected light distribution on the right side Figure 1 Therefore, it is important to ensure the accuracy of the sampling operation for the object to be tested.

[0148] Reference Figure 2E As shown, Figure 2E The left side shows the original light dot layout of the object to be tested (physical irregular-shaped light board) corresponding to the aforementioned virtual irregular-shaped light board. It is assumed that the user-set preset dot density is 2×2. Figure 2E The right side shows the actual distribution of light spots displayed according to the preset dot matrix density for the object to be detected, as shown in Figure 2. Figure 2E In the actual distribution diagram of the light points, the light points that should be lit within the rectangle in Figure 2 are not lit, that is, Figure 2E The actual light distribution diagram on the right is shown in Figure 2. Figure 2C The expected light distribution map on the right is inconsistent, therefore, the sampling operation to determine the object to be tested is inaccurate.

[0149] During the production process, comparing the expected LED distribution diagram with the actual LED display distribution diagram can detect manufacturing defects in the display screen. In the research and development phase, this comparison helps engineers assess whether a newly designed display screen meets performance requirements.

[0150] This application provides a method for detecting the correctness of light panel spot selection. In response to a user's setting of the dot matrix density, a predicted light spot distribution map of the object to be tested is generated. The predicted light spot distribution map represents the light spot distribution map of the object to be tested after the preset dot matrix density is set to be illuminated at intervals. The object to be tested includes at least one irregularly shaped light panel obtained by performing spot selection on a rectangular light panel. The object to be tested is controlled to display at intervals according to the preset dot matrix density to obtain the actual light spot display distribution map of the object to be tested. Based on the actual light spot display distribution map and the predicted light spot distribution map of the object to be tested, the correctness of the spot selection operation on the object to be tested is determined. Since the object to be inspected refers to at least one physically irregularly shaped light panel, and the virtual irregularly shaped light panel corresponding to each physically irregularly shaped light panel is a virtual irregularly shaped light panel obtained by sampling points from a virtual rectangular light panel, the software generates an expected light point distribution map corresponding to the object to be inspected based on the preset dot matrix density set by the user. This provides a benchmark for subsequent sampling point inspection. The software further controls the object to be inspected to display points at intervals according to the preset dot matrix density to obtain an actual light point display distribution map. By comparing the expected and actual light point distribution maps, the correctness of the sampling point operation can be evaluated. This method of automatically controlling the light points on the irregularly shaped light panel to display points at intervals simplifies the operation process. After sampling points on the light panel, it improves the efficiency of detecting whether there are errors in the sampling points, which helps to improve product quality, reduce rework and scrap rates, thereby reducing costs and improving production efficiency.
