In this paper, a robust stable three-dimensional (3D) seam tracking method is investigate based on the Kalman filter (KF) and machine learning during the multipass gas metal arc welding process with a ...

In this project an algorithm was developed to autonomously detect 3D weld seams on workpiece of any geometrical shape using Point Cloud Library. Further we used Neural Networks to trace the detected ...

Therefore, an economical 3D measurement sensor based on structured light technique is proposed in this paper. Calibration methods of the sensor are investigated. Experiments for sensor calibration ...

Tracking in the "city frame" is advantageous over tracking in the egovehicle frame or camera coordinate frame since parked cars are constant in the city frame. You can find our technical report here ...

Three-dimensional (3D) zigzag-line welding seams are found extensively in the manufacturing of marine engineering equipment, heavy lifting equipment, and logistics transportation equipment. Currently, ...

ABSTRACT: Weld seam deviation prediction is the key to weld seam tracking control, which is of great significance for realizing welding automation and ensuring welding quality. Aiming at the problem ...

Achieving quality weld in robotic arc welding processes is challenge due to workpiece fixture accuracy and variation in workpiece manufacturing processes. Many methods have been developed to measure ...
