Abstract: Acquiring 3-D surface information by means of laser triangulation is a kind of active vision measurement.In order to improve the measurement speed,a fast 3-D information acquisition and surface reconstruction system based on smart camera and laser triangulation was presented.The hardware construction and data processing flow of the system was introduced.Because of applying of the digital signal processor(DSP) and parallel processing,the result of experiment shows that the speed of acquisition can reach 5600 dots/s.
