Based on synchronized scanning triangulation standard structure, an abnormal structure of synchronized scanning triangulation is put forward. The principle of synchronous scanning triangulation ranging system is introduced, the system model is established, and the 3D space coordinate expression is obtained. For synchronous scanning triangulation ranging system of four kinds of special-shaped structure is analyzed, the result data is obtained through simulation analysis, and the best structure d85 is found out. The d85 synchronized scanning triangulation ranging system prototype is designed and manufactured, and 3D point cloud data is obtained by testing.
