Review of Three-Dimensional Imaging Techniques for Robotic Vision

The three-dimensional (3D) imaging techniques of robotic vision in the field of intelligent manufacturing robot vision perception arc reviewed. The characteristics and limitation in practical applications of some typical robot vision imaging methods are systematically summarized. The content involves time-of-flight imaging, point and line scanning imaging, chromatic confocal imaging, structured light projection imaging, deflectometric imaging, monocular and multi-view stereo imaging, and light field imaging. The tree map of various robotic vision imaging methods arc drawn. The best 3D imaging methods of cyc-in-hand robotic system arc discussed.
