| Abstract: | This project is designed for 3D scanning with 360° degree which can obtain the 3D accurate information in real time. SCM controls the AC servo motor to circumrotate in the optional angle, speed and direction. Moreover, SCM delivers the time and angle data to the PC for further operation. In this project, the precision of the circumrotating has been examined and dominated. Furthermore, the sources of errors have been researched and the actual errors have been quantitative analyzed with some methods for amelioration, such as eccentric correction and 4 frequency apartment, which improved the precision of the system parameters. The angle range is 360° degree and the maximum angle resolution is 0.01° degree. |
