The decoupling visual feature extraction of dynamic three-dimensional V-type seam for gantry welding robot
During the welding manufacturing of a circular pressure vessel, the V-type seam’s position relative to welding torch varies dramatically due to the seam curvature change or axial asymmetry movement. Thus, a de...
