Abstract

The invention discloses a method and a device for correcting a display screen. Among them, the method includes: collecting the brightness and chromaticity information of each light point through the relative movement of the image acquisition device and the screen body; calculating according to the brightness and chromaticity information of each light point to obtain the surface coefficient of each light point; Correct the surface of the image collected by the image acquisition device to obtain the corrected image; correct the display screen according to the corrected image. The invention solves the technical problem that the prior art cannot overcome the poor driving effect of the LED screen after correction in the process of correcting each light point in the LED screen.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for correcting a display screen. Background technique [0002] With the development of LED display technology, LED displays are currently being applied to various fields due to their advantages of low cost, low power consumption, high visibility, and free assembly. At the same time, with the popularization of LED display applications, users have higher and higher requirements for their display quality, so how to improve the display quality of LED displays has become a research hotspot in this field. [0003] However, in the process of improving the uniformity of the LED screen, for the correction process of the camera vignetting and the LED light distribution curve, the real brightness and chromaticity are obtained by fitting the collected LED display data, and then the correction coefficient is calculated. The curved surface is greatly affec...
