摘要
本设计主要用于360°旋转的三维扫描,实现角度数据的实时获取。设计中采用单片机控制交流伺服电机进行自定的角度、速度与方向的旋转并实时上传时间、角度数据至上位机进行处理,实现了对平台旋转精度的控制与检测,着重研究了该传感器误差源的产生,对实际应用中的误差进行了定量分析,利用偏心改正、4分频等方法减少了误差,提高了参数精度。角度范围为360°,角度分辨率为0.01°。
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 cireumrotate 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.
