Abstract: In order to make it easy for stereo matching in the stereo vision measurement, a stereo vision method along the optical axis was proposed. Based on a coordinate measuring machine, pictures were captured by only one camera along an optical axis, matching was simplified by pairs of parallel Epipolar lines in this special structure and the 3D data was obtained by the stereo vision theory. Results of the experiment on measuring a plate prove that this method can finish the measurement swiftly and reduce the errors of matching.
Key words: stereo vision along an axis; stereo matching; epipolar line restriction; coordinate measuring machine
