LED splicing gap bright and dark line correction method and device, storage medium and terminal

Abstract

The invention discloses an LED splicing gap bright and dark line correction method and device, a storage medium and a terminal. A splicing gap is corrected through a correction coefficient corresponding to the splicing gap; the phenomenon that visual bright and dark lines exist between the display units (modules or box bodies) of the LED display screen during watching due to splicing gaps caused by reasons such as the machining precision and the assembling precision of the display units (modules or box bodies) can be rapidly and accurately improved; the scheme is not influenced by the environment, the visual bright and dark lines at the abutted seams can be quickly corrected while correction is performed, and the time for manually correcting the seams of the display units (modules or box bodies) is saved; according to the scheme, a Gaussian filtering method is adopted, and the optimal difference of the gap splicing effect can be judged by calculating the number of steps of a smooth one-dimensional curve; the correction coefficient is calculated by extracting the pixel gray average value, so that the acquisition error can be reduced, and the problem of excessive correction or insufficient correction is avoided.

Description

technical field [0001] The invention relates to the technical field of LED display screen acquisition and correction, in particular to a method, device, storage medium and terminal for correcting bright and dark lines in LED splicing gaps. Background technique [0002] LED displays are generally composed of multiple display units (modules or cabinets) spliced ​​together. Due to the limitation of processing accuracy and assembly accuracy of display units (modules or cabinets), the splicing gap between adjacent display units (modules or cabinets) may be different from the pixel points inside the display unit (module or cabinet) The spacing is inconsistent, which makes people feel that there are bright and dark lines at the screen splicing gap when watching images. It is not easy to notice when the pixel pitch is large, but as the pixel pitch gradually becomes smaller, this phenomenon is particularly obvious, seriously affecting the display effect. [0003] Therefore, the exi...
