LED screen correction method and correction device

Abstract

The invention relates to the technical field of LED display screens, and particularly discloses an LED screen correction method and correction device, and the method comprises the steps: obtaining a picture of an LED screen; marking lamp points in the picture of the LED screen, and determining an area where the lamp points are located, coordinates of the lamp points, RGB values of the lamp pointsin the area and radiuses of the lamp points; removing lamp points with abnormal colors according to the RGB values of the lamp points in the area; removing lamp points with abnormal radiuses accordingto the lamp point radiuses; removing lamp points with abnormal lamp point distances according to the areas where the lamp points are located and the lamp point coordinates; clustering analysis is carried out on the remaining lamp points in the picture of the LED screen, selecting the class with the number closest to the number of the actual lamp points as an effective lamp point, and generating acorrected picture; and correcting the LED screen according to the correction picture. According to the LED screen correction method and device, correction of the LED screen is achieved, the influenceof ambient light on the LED screen correction process is effectively avoided, the correction effect under the ambient light is improved, manpower and material resources input in the correction process are reduced, and the correction quality and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to an LED screen calibration method and calibration device. Background technique [0002] During the calibration process of the LED display, due to the influence of ambient light, the calibration effect of the LED display is very poor during the day or when the lights are turned on, and even cannot be corrected. Usually, it can only be performed in a dark environment at night or specially A correct calibration darkroom can avoid the influence of ambient light on the calibration. Therefore, the ambient light brings a lot of inconvenience to the LED screen calibration process, and the effective time for calibration is too small, so that the calibration engineers can only work night shifts, which not only wastes a lot of manpower and material resources, but also seriously affects the calibration quality and efficiency.
