Study on Weld Seam Tracking System Based on Laser Vision Sensing

Abstract

The seam tracking system is designed for welds with very small gaps. This system is based on vision sensing technology. This system uses LED lamp as auxiliary light source, CCD camera as image acquisition unit and industrial computer as system control core. This system can extract the weld location information through a variety of image processing algorithms. After calculating the position deviation between the weld seam and torch, the system can control the actuator to look for the center of the weld. So the goal of weld seam tracking can be achieved.
