英文摘要：

In order to realize the three-dimensional measurement of the objects regardless of far or near and expand the measurement range, a laser triangulation system based on synchronized scanners with LIDAR was established. Its principle, design and device selection were investigated. First, according to the synchronous scanning mechanism, the LIDAR technology was fused based on traditional three- dimensional measurement and the computational formula of the 3-D points was deduced. The selections of laser device, lens, and dichroscope, scanning servo motor, LIDAR acceptor and camera were analyzed based on system design requirement. After that the mechanical structure was designed and the light path of optical system was simulated by Zemax to prove the feasibility of principle. Finally, the back of light of APD was tested and the actual object was scanned to acquire 3-D point clouds. The experimental results show that the system is feasible.
