Automatic welding robot path planning and application instance based on 3D vision technology

Abstract

Based on 3D vision technology,automatic welding robot path planning system is put forward.Two kinds of image processing technology Sobel and Laplace algorithm are used in this system to calculate cloud edge of 3D scanning points and remove outliers,and obtain the smallest cost of scan and time calculation.This system also provides a convenient interface for users,not only can modify the welding torch orientation,but also develop new welding task.In this paper,3D vision technology has been successfully used for the measurement of the workpiece with complex geometrical shape as well as the welding process.
