Research on Welding Spot Extraction Technology in Ship Assembly Welding Process Based on Machine Vision Tracking
A research on welding point extraction technology based on machine vision tracking guidance was carried out in response to the welding process requirements of ship segmented groups.Firstly,the research status of solder joint extraction technology at home and abroad was introduced.Secondly,the common joint forms of welded workpieces were analyzed.Again,a self-developed visual tracking guidance sensor was used to collect laser line images of the workpiece,and the laser center of gravity was extracted based on the grayscale centroid method.Finally,the slope of the optical center was calculated based on the average slope method,and the monotonic range of the optical center contour was extracted.The maximum span monotonic range was extracted based on the geometric characteristics of the transition point,and the coordinates of the solder joint were determined.Finally,a welding experiment was conducted on the group assembled parts,achieving good welding quality.
