Abstract :In this article both stereo vision and line2laser scan sensor are integrated to CMM,according to this measuring system the bound2 aries or outlines of object are obtained by stereo vision and the ostensible data of object are achieved by line2laser scan sensor. Information fusion of multi2sensor can be utilized to segment 3D data、to abstract the geometry characteristic of the object、to construct the object modeling.Muliti2 sensor integrated coordinae measuring system avoids the limits of a single sensor ,and provides a new road for non2touch measuring system in the application of reverse engineering.
