Abstract

The invention discloses a visual positioning system and method for alignment assembly of a display screen module, and the method comprises the steps: carrying out the analysis of an alignment assembly state gray image through employing an image processing and analysis algorithm based on the artificial intelligence and machine vision technology; in this way, multi-scale enhanced fusion features related to display screen module images are captured, and then image distortion correction is carried out by using the features to generate a distortion-corrected alignment assembly state grayscale image. Thus, the corrected image is used for calculating the positioning deviation and adjusting the pose of the display screen module, the precision and efficiency of alignment assembly of the display screen module can be improved to a great extent, meanwhile, human errors are reduced, and the consistency of product quality is ensured.
