Colorlight has obtained the special-shaped LED display technology patent, which can facilitate subsequent light point calibration work.

The patent abstract shows that the present invention discloses a method, device and system for sorting light points in a special-shaped LED display screen. The method includes: determining the number of corner points of the special-shaped LED display screen and the two bottom corner points through a convex hull algorithm, and performing perspective transformation on the first image of the special-shaped LED display screen based on the two bottom corner points to obtain the perspective transformation. The second image after replacement; determine the surrounding light points and preset areas of each light point to be sorted in the second image, traverse all the light points in the special-shaped LED display screen, and determine the positional relationship between the corresponding surrounding light points and the light points to be sorted, until the rows and columns of all light points are determined to sort the light points in the special-shaped LED display screen. It can determine the point coordinates during perspective transformation based on the corresponding corner points of the special-shaped LED display, perform perspective transformation on the special-shaped screen, and determine the rows and columns of the light points based on the relationship between each light point and the surrounding light points and the preset area, thereby sorting the light points in the special-shaped screen to facilitate subsequent light point correction work.
