Abstract

The invention discloses a method, a device, a storage medium and a terminal for correcting bright and dark lines in LED splicing gaps. The splicing gaps are corrected through correction coefficients corresponding to the splicing gaps, which can quickly and accurately improve the processing of display units (modules or cabinets). There are visual bright and dark lines between LED display units (modules or cabinets) caused by stitching gaps due to reasons such as precision and assembly accuracy; this solution is not affected by the environment, and can quickly correct the stitching while correcting The visual bright and dark lines at the place can save the time of manually correcting the gap of the display unit (module or cabinet); this solution adopts the Gaussian filter method, and can judge the gap splicing effect by calculating the number of steps of the smooth one-dimensional curve Pros and cons: By extracting the pixel gray mean value to calculate the correction coefficient, the acquisition error can be reduced, and the problem of over-correction or under-correction will not occur.

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...
