| Abstract: | A 3D laser scanning measure system based on computer vision was introduced. It was composed of a binocular measuring sensor based on vision, image acquisition cards, scanning part and control part. By means of collecting the images with a laser strip by two CCD cameras and matching the image, the position and depth of points on the scanning laser strip can be obtained by the disparity. The CCD camera calibration, image collection, feature extracting and matching, 3D shape information recover in the system were discussed. The system can be used in reverse engineering. |
