Abstract: In order to realize the dimensional inspection requirements of the ultrasonic welding machine to the lamp holder after welding, a set of dimensional inspection system based on machine vision is designed. An improved Canny algorithm is proposed to extract image edges, and it is applied to line segment detector (LSD) algorithm to extract straight line segments. Through comparing the measurement results of the detection system in this paper with the standard size, the accuracy of the detection system in this paper is increased by 7%, and the speed is doubled. The size detection system designed based on the improved algorithm effectively improves the detection accuracy and efficiency, and has certain application value in industry.
