中文摘要：

将傅立叶变换轮廓法用于机器人等离子熔射成形过程中零件的三维形貌检测，目的是在满足一定精度要求的前提下，对机器人成形加工过程中被加工体进行现场检测和实时控制，并对成形过程工艺参数进行反馈修正，提高成形精度。详细论述了该方法的测量原理，零件形状与所对应的相位之间的关系，建立了三维形状测量的系统构架，最后给出了测量结果并提出了误差来源和改进措施。

英文摘要：

In this paper, Fourier transform profilometry is applied to obtain the 3- D profile of parts, and the main purpose is to develop real time measuring and control system provided that the certain precision of the method is kept, thus to control the growth of the coating and improve its quality. The phase measurement principle of the method,the relationship between object profile and the required phase are addressed in detail. The system structure of the 3 - D measurement is also set up. The experimental results based on the method are given at the end,and also the error sources and improvement methods are brought forward.
