Abstract: A portable 3D laser scanning measure system based on stereo vision is introduced. 5 lasers were fixed in de visual sensor, so the scanning speed could be increased by 5 times. By means of collecting the images with laser strips by two CCD cameras and matching the image, avoided the calibration of the laser. The position and depth of points on the scanning laser strips can be obtained by the disparity. With explaining the principle and method used in the measurement of 3D contour, the result of experiment shows the preciseness of the measurement system.
