3D vision technology and its applications in welding

Abstract

3D vision technology is one important branch of machine vision, whose aim is to derive an accurate description and measurement of object in 3D scene from 2D image. At present, it is an important research domain in robot, measurement and artificial intelligent fields. The automatization, roboticization and intelligentization are the development trends of welding technology. The vision sensing method is the key to realize the automatic welding. The research of machine vision has been applied in welding field and made great progress. The 3D vision technology and its application research in welding are introduced in this paper. Finally the further development of 3D vision in welding is prospected.
