MACHINE VISION-BASED WINDSHIELD SCRATCH CONTINUOUS-DETECTION APPARATUS AND DETECTION METHOD

摘要

A machine vision-based windshield scratch continuous-detection apparatus and detection method. The apparatus comprises a conveying device (1), cleaning devices (2), illumination devices (3), and image acquisition and processing devices (4). The conveying device (1) is wholly installed on a support frame (5), the upper and lower parts on the right side of the support frame (5) are dark chambers, and the right side surface of the support frame (5) is hollowed out. A cleaning device (2), illumination devices (3), and an image acquisition and processing device (4) are provided inside each dark chamber. A windshield is fixed by the conveying device (1) and conveyed to the dark chambers, the cleaning devices (2) clean the windshield entering the dark chambers, and the number of the illumination devices (3) used is determined by the size of the windshield. Upper and lower industrial cameras (45) continuously detect the front and back of the windshield, and send captured images to industrial computers to process and analyze the images, so as to finally determine whether there are scratches on windshield surfaces. The apparatus analyzes images on the basis of machine vision, and can adapt to windshields of different sizes, and the number of the illumination devices (3) can be adjusted to save power.
