Research on Key Technology of Welding Robot Positioning System Based on Vision Feedback
In order to realize remote welding operation in complicated and dangerous environment and improve the automatic level of remote welding robot, the author has designed a set of welding robot positioning system based on vision feedback under special circumstances. Stereoscopic vision technology has been adopted to carry out task space analysis. The system will first calibrate the internal and external parameters of the camera and the hand-eye relation of the robot and then adopts stereoscopic vision technology to carry out task space analysis and stereoscopic reconstruction for the remote welding. Before arc striking, the robot remote welding task program will be generated first through image matching technology under the assistance of stereoscopic vision system. Then, the high-speed macro guidance in the free motion area and the lowspeed guidance positioning in the restricted motion area are carried out by manual control. Finally, the welding task can be completed through of on-the-spot vision assistance. The test shows that this system is capable of effectively perceive the features of the remote operational environment, thus laying foundation for the independent welding of welding robot.
