Abstract

The methods of vision recognition, position and orientation in a flexible automatic coordinate measuring system (FACMS), which is formed by integrating computer vision and computer aided inspection planning with CNC-coordinate measuring machine, are discussed in this paper. The working principle and working process of multiple orientation run length coding, the vision recognition method used in the FACMS, are presented elaborately. Based on the moment of inertia of the binary image of workpiece, the methods of position and orientation are presented here. The research work in this paper shows that it is feasible and effective to integrate computer vision with measuring systems, so as to increase their flexibility and automation.
