Abstract :
This paper proposes a new 3D reconstruction method of on-machine workepieces images based on projective rectifications. A set of monocular stereo system which uses a five-dimensional manipulator carrying a CCD camera was established on the NC milling machine. Projective rectification was used to stereo match in virtue of dimension reduction of match search. 3D reconstruction of the on-machine workpiece are carried out including steps of system calibration, projective rectification, image transformation, image matching and depth calculation. The application results show that this method can make full use of digital controlled machine tool feed movements to realize the measuring and manufacturing integration.
