Abstract

The embodiment of the invention provides an image processing method, an image processing device and an image processing system. The image processing method is applied to display screen correction, for example, the image processing method comprises the following steps: acquiring an acquired image obtained by shooting a target display screen by an image acquisition device and original resolution information of the image acquisition device; analyzing the acquired image to obtain image rotation information and a pixel data value corresponding to each pixel point; allocating a storage space according to the original resolution information; determining rotation information of the target display screen according to the image rotation information; based on the rotation information of the target display screen, reading pixel data values of the acquired image and storing the pixel data values in a storage space, wherein the positions of the pixel data values stored in the storage space are in one-to-one correspondence with the positions of display lamp points of the target display screen. According to the image processing method provided by the embodiment of the invention, the problem that an LED display screen cannot be corrected normally after the LED display screen is rotated is solved.

Description

technical field [0001] The invention relates to the technical field of display screen correction, and in particular to an image processing method, an image processing device and an image processing system. Background technique [0002] At present, when correcting the LED display screen, it is necessary to use a camera to take pictures of the LED display screen first, and then analyze and collect the image to obtain image data, so as to perform calibration of the LED display screen. In this process, the LED display screen must not be rotated, that is, The LED display shows the positive image. [0003] When the direction of the LED display is rotated, whether it is the rotation of the physical orientation or the rotation of the image displayed on the LED display by the software, when the camera takes pictures of the LED display, due to the limitation of the camera's own hardware, the camera obtains The pixel points in the captured image cannot correspond to the positions of t...
