3D Reconstruction of Weld Pool Surface in Pulsed GMAW by Passive Biprism Stereo Vision
RA-L 2019
Geometrical information of the 3D weld pool surface provides clues to determine the penetration state whose monitoring and feedback control are crucial for critical applications involving high temperatures and pressures. In this letter, a biprism stereo vision system is established to sense the weld
