Path planning method for LED special-shaped screen

Abstract

The invention relates to a path planning method for an LED special-shaped screen, which comprises three steps that firstly, two layers of coordinates are set for two pixel points; secondly, specific scanning is performed on each path; and thirdly, processing is performed on intersected paths. According to the invention, path planning is performed through extraction for pixels, and data of corresponding pixel points in the video can be extracted according to the line direction of the special-shaped screen, thereby facilitating data extraction in the LED special-shaped screen, and breaking through limitations of data extraction in the traditional LED display screen.

Description

technical field

[0001] The invention relates to data extraction in LED display screens, and is a path planning method for LED special-shaped screens. Background technique

[0002] At present, LED display screens are widely used. There are many kinds of LED display control systems and supporting systems on the market. The first control method is to use video decoding to obtain video data, and the data is completely in the form of the original video file. Arrangement, the second control method is developed and designed according to the characteristics of LED matrix display. The data output by the two control methods cannot be arranged randomly according to the special requirements of LED special-shaped screens, and are only suitable for LED rectangular dot matrix displays. Moreover, when using a video card for video processing, the video card must also be connected to a PC, and offline control cannot be realized, which limits the application occasions of the LED display.
