Abstract

The invention discloses an LED display screen splicing error detection method and a detection device, wherein the method comprises the following steps: acquiring an image of a spliced region of an LED display screen; recognizing first LED pixel points and second LED pixel points from the image; acquiring the location of the first LED pixel points in the image and the location of the second LED pixel points in the image; and on the basis of the location of the first LED pixel points and the location of the second LED pixel points, determining a splicing error of the LED display screen, wherein the image is obtained by shooting the spliced region; the LED display screen comprises a first display unit and a second display unit; the spliced region is obtained by splicing the first display unit and the second display unit; the first display unit comprises a plurality of the first LED pixel points; and the second display unit comprises a plurality of the second LED pixel points. The detection method and the detection device disclosed by the invention can solve the technical problem that an LED screen, acquired by related technologies, is relatively low in splicing error precision.

Description

technical field [0001] The invention relates to the field of display equipment, in particular to a method and device for detecting splicing errors of LED display screens. Background technique [0002] The LED screen is spliced ​​by many small-sized units, all of which are spliced ​​manually at the construction site, so that positive and negative splicing errors cannot be avoided. Positive errors mean that there are gaps between units, and between two adjacent columns or rows of lights The distance is greater than the pixel pitch. When viewing images on a screen with gaps, there will be dark lines in the gaps of the screen; negative error means that there is extrusion between units, and the distance between two adjacent columns or rows of lights is smaller than the pixel pitch. When viewing images on the screen with extrusion phenomenon, bright lines will be generated at the extrusion position of the screen, which will affect the display effect and display quality of the LED ...
