Methods of Automatic Correction of Technological Trajectory of Laser Welding Complex by Means of Computer Vision

The paper deals with the problem of developing a system for automatically correcting the technological trajectory in the working space of a laser robotic complex in the pre-process. To solve this problem, a method was proposed for correcting the points of the technological trajectory based on detecting and recognizing the edges of the joint of welded workpieces in the image obtained from a CCD camera mounted on an industrial complex tool. To do this, they performed a preliminary segmentation of the separating line, then made a recognition of the edges of the workpieces and determined the correction point relative to the position of the tool. The results of the work were successfully tested at the industrial complex of laser robotic welding.
