In this paper, a visual control system is proposed to locate the start welding position and track the narrow butt welding seam in container manufacturing. It estimates the error between the welding torch and the welding seam with a camera and a panel computer. It adjusts the torch’s position via a stepper motor to eliminate the error. A decision controller with three gates is designed to decide the...
An image-based visual system is proposed for narrow butt welding seam tracking in container manufacturing. A smart camera is used as the sensor to measure the welding seam. The feature extraction algorithm is designed based on the smart camera, which is used to compute the error between the welding torch and the welding seam. The reference feature is determined with many frames of images based on...
Aiming at the requirement of power line inspection robot, this paper develops and builds a vision system depending upon the TMS320DM642 as the core, which can realize the image collection and display, implement the image features extraction. Through the extended UART interfaces, this system can communicate with the control unit of Power Line Inspection Robot. Corner coordinates obtained from the algorithm...
This paper put forwards a corner detection solution and develops and builds a vision system depending upon the TMS320DM642 as the core, which can realize the image collection and display, implement the corner detection algorithm. Through the extended UART interfaces, this system can communicate with mobile robots of power lines. Corner coordinates obtained from the algorithm of this system can be...
