Abstract
The present invention discloses a ceramic ball automatic sorting system and method. The system automatically sucks a ceramic ball on a ceramic ball feeding track for image acquisition, identifies whether the ceramic ball is defective according to the acquired image information, and determines a ball storage device into which the ceramic ball is placed, and the whole process does not require manual participation, which achieves the automation of ceramic ball defect identification and sorting and improves the ceramic ball defect identification accuracy and sorting efficiency. According to the method, images of the ball surface shot at each angle are automatically spliced by using an automatic image splicing technology to achieve full coverage. A defect is identified by using a threshold segmentation algorithm according to a set threshold, and whether the ceramic ball is defective and the ball storage device where the ceramic ball should be placed are determined, thereby achieving the automation of ceramic ball defect identification and sorting, and improving the ceramic ball defect identification accuracy and sorting efficiency.
