Paper Abstract

Registration local sets of points for obtaining one final data set is a vital technology in 3D measurement of large-scale objects. In this paper, a new optical 3D measurement system using finge projection is presented, which is divided into four parts, including moving device, linking camera, stereo cameras and projector. Controlled by a computer, a sequence of local sets of points can be obtained based on temporal phase unwrapping and stereo vision. Two basic principles of place dependance and phase dependance are used to register these local sets of points into one final data set, and bundle adjustment is used to eliminate registration errors.
