介绍了增量型编码器以及GPS的工作原理及性能参数,阐述了两者在道路检测车中的使用方法和理论依据,得出了两者同时使用能有较高的测量精度的结果,同时也指出了两者的不足,为后续的改进提供参考。
The working principle and performance parameters of incremental encoder and GPS are introduced. The using method and theoretical basis of the two in road test vehicle are expounded, and the results that both of them are used at the same time with higher measurement precision are obtained. At the same time, Also pointed out the shortcomings of both of them and provided reference for the subsequent improvement.
