Objective To construct a system for three dimensional face scanning and measurement. Methods The measurement system was based on the principle of triangulation and the combination of gray-code and phase-shift structured light projection. The system software was developed for Windows XP with the aid of tools such as Visual C++ and Hoops. Results A three dimensional measurement system based on structured light projection was developed. The system hardware was composed of fringe projection unit, image gathering unit, system control unit and mechanical appearance, and the system software was composed of point cloud display and editing module. The lamp house of the system was 12V, the working distance was 900 mm, the scanning time was 5.5 s and the scanning field was 500 mm×400 mm. Conclusion The three dimensional measurement system based on structured light projection is a refined machine with safe light to eyes, and the accuracy and scanning speed are suitable to face scanning.
