If the target configuration information is not available, the system does not determine which target pin of which driving chip the image data output by the display card is transmitted to drive the light emitting device to display, so that the purpose of configuring the display screen is realized, manual deep intervention is required when the display screen is configured, and possible errors are introduced.
The method in the embodiment can be applied to the special-shaped screen, the target configuration information is generated through the cascading topology information of the light emitting devices of the display screen and the target position information of the light emitting devices to be displayed, which is obtained based on computer vision, and then the target configuration information is issued to the control equipment to configure the display screen, so that a complex configuration mode of the display screen in the related technology is simplified, the situation that points are traced manually according to the positions of the light beads lighted each time of the display screen is avoided, and the configuration process of the display screen is complicated and errors possibly introduced are avoided. Because the embodiment adopts the target configuration information to directly configure the display screen, manual depth intervention during the configuration of the display screen can be reduced, the accuracy and the speed of configuring the display screen are greatly improved, the problem that the display screen is configured to fail or the display screen is configured to be offset due to slight carelessness in the dot-tracing process in the display screen configuration method in the related art is avoided, the configuration time of the display screen is shortened, the display screen is more reliably configured, the technical problem that the repeated configuration process of the display screen is required in the related art, the efficiency of configuring the display screen is low is avoided, and the efficiency of configuring the display screen is improved.
Example 2
The above-described method of this embodiment is further exemplified below.
The display screen is developed rapidly due to the advantages of high brightness, wide color gamut, flexible splicing, flexible size and shape and the like. The display screen used in most occasions is often a standard display screen which is formed by splicing lamp boxes with the same specification, wherein the specification of the lamp panels is the same, the wire arrangement mode is the same, the size of the whole box body is the same. When the display screen is used, the display screen is spliced, so that the number of rows and columns of the box body and the number of receiving cards to be carried by the network port are required to be adjusted after the display screen is lightened, and the display screen can display a correct picture after the display screen is lightened. When the display screen is configured, a point-by-point connection screen configuration mode is generally adopted, the topology information of the lamp bead positions on one lamp panel is mainly configured, the configuration of the single lamp panel/box body is expanded to the whole box body, screen configuration software on a computer can calculate the position topology information of the whole screen by utilizing the preset network port number and the receiving card topology mode, and the LED display screen can be completely configured by tightly matching human and machine. The method is more suitable for the standard display screen which is formed by splicing lamp boxes with the same specification, the same wire arrangement mode and the same size of the whole box body.
However, with the increase of application scenes of the display screen, the form of the display screen is changed into a special-shaped screen from a regular rectangular display screen. Aiming at special-shaped screens, such as hollow display screens in physics like Chinese knots, paper cuts and characters, the arrangement modes of the lamp beads are inconsistent, the number of the lamp beads in each scanning area is inconsistent, the positions of the lamp beads which are lighted each time on the display screen are manually traced, and a computer calculates a routing table (coordinate information of the lamp beads which are lighted in sequence) according to tracing information. Because the positions of the lamp beads of each sweep are irregular, the tracing points are easy to be in serial, the deviation of the number of the tracing points occurs, once the tracing points are in midway error, the tracing points are found to be abnormal when the display screen is lightened to display images, and the display screen needs to be restarted to be configured. Therefore, the accuracy and efficiency of manual dotting information extraction can be greatly reduced for the configuration of the special-shaped screen.
In addition, for large-scale use of the special-shaped screen, the configuration mode of the display screen is slightly insufficient due to factors such as inconsistent size and inconsistent shape of the box, so that the configuration mode of the whole display screen is not suitable for the configuration of the special-shaped screen through configuration of a single lamp panel or the box, and particularly, the special-shaped screen in a hollowed shape is a front cut.
Therefore, the existing display screen configuration method is difficult to configure the display screens with inconsistent specifications of the special-shaped screen and the box body, human resources are consumed for a long time, at least one scan of coordinate information needs to be manually extracted in an auxiliary mode, the screen configuration can be completed only by manual deep intervention, and the accuracy and precision of the screen configuration cannot meet the requirements.
However, this embodiment provides a simple and convenient autonomous configuration mode and configuration system for the special-shaped screen, the point tracing information of the LED is extracted in a machine vision mode, and the point tracing information is calculated to generate a routing table, so that the accuracy is improved and the efficiency of configuring the display screen is improved based on the routing table.
The method of this embodiment is further described below.
The embodiment will be briefly described by taking the special-shaped screen with the hollowed-out pattern which is the most difficult to configure in practice as an example, but the special-shaped screen of the embodiment is not limited to the shape shown in fig. 3, and the embodiment can be applied to the configuration of all hollowed-out special-shaped screens.

In the actual process, the driving chips are respectively cascaded to drive and light up so many lamp beads.
For convenience of explanation of the specific implementation procedure, a scan of the display screen will be described as an example. Fig. 4 is a schematic diagram of topology information of a sweep of data according to an embodiment of the present invention. As shown in fig. 4, a one-scan cascade method of driving chips is shown, and it can be known from an electrical network table in a schematic diagram, and the cascade topology information can be what pin of which driving chip is used to drive any LED lamp bead. For example, if the last LED bead is the 16 th pin driver of the nth driver chip, the cascade topology information may be represented as the data location (N, 16) of the bead. This embodiment can know how many beads and driver chips are in common for this scan by illuminating all beads for this scan. Thus, the data position of the first LED1 bead in the driver chip 1 may be D (1, 1), the data position of the second LED2 bead in the driver chip 1 may be D (1, 2) … …, the data position of the 1 st LED1 bead in the driver chip 2 may be D (2, 1), the data position of the 2 nd LED2 bead in the driver chip 2 may be D (2, 2), and so on.

After this embodiment, if the coordinate position information is a decimal, the coordinate position information may be subjected to rounding processing or pixel aggregation processing may be required. For example, the coordinate position information is P (1, 1.5), and for a general scene, the coordinate position information may be processed according to the P (1, 2) position, but this may cause the pixel point to shift; alternatively, this embodiment performs pixel aggregation processing on the coordinate position information P (1, 1.5), and may perform weighted average on the pixel information of the P (1, 1) and P (1, 2) positions, and then use the obtained weighted average as the information of the P (1, 1.5) position.

As shown in fig. 7, 1 in fig. 7 is a sequence of lighting LEDs on a display screen, 2 is a camera and image information captured by the camera, and 3 is a wiring sequence obtained by image processing.
After this embodiment, in order to achieve full topology information coverage, the type of driver chip needs to be configured, and the display screen may illuminate each sweep of beads in sequence, one by one. The image processing link at least comprises algorithms such as image acquisition and noise reduction, feature detection and matching, inclination correction and the like.
According to the embodiment, the data position D of the lamp beads can be recorded when the image display of the luminous lamp points is controlled, the corresponding position coordinates P (point tracing vector information) are calculated through computer vision by utilizing the image of the luminous lamp points, the pixel information of the corresponding position coordinates can be taken out according to the position coordinates P and the data coordinates D and transmitted to the data positions of the LED lamp beads, and the corresponding lamp beads display the corresponding pixel information. A scanning routing table can be generated according to the relation, each scanning routing information table is generated, namely, the routing table of the whole screen is formed, and the computer is further combined with the driving chip type and the decoding chip type to calculate and generate a configuration file.
Optionally, after this embodiment, with the data position D and the position coordinate P of the light bead, the screen configuration software on the computer can calculate the routing table (large table) of the whole screen by using the preset number of network ports, the topology mode of the receiving card and the connection sequence information. The sending card and the receiving card distribute and extract the data of the corresponding lamp beads according to the routing table so as to accurately send the pixel information (gray data) of the LEDs to the corresponding lamp beads for display.
