Composite Measurement Method Based on Computer Vision Technology

Abstract:

Based on analyzing current methods of acquiring point clouds data in reversing engineering, considering the features of structure light scanning and binocular stereovision, we proposed a composite measuring method based on vision technology, which combines the advantages of the two measurement methods in together, and established the measuring system. The greatest advantage of this method is that the edge data were obtained by binocular vision technology, and the internal data were obtained by Structure light method. In binocular vision, stereo matching was realized with the combination of epipolar constraint, corner feature matching and area matching, which could improve location precision and matching speed of feature point. An application example shows the composite measuring method is feasible.
