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.
