相位检测面形术在大尺度三维面形测量中的应用

Phase-Measuring Profilometry in Big Scale Measurement

将相位检测面形术 (PMP)用于大尺度、高精度三维面形测量中。采用文中提出的双向高度坐标校正法 ,可以得到精确的物面三维坐标。提出了一种新的基于洪水算法的图像拼接法 。

The phase measuring profilometry (PMP) is applied in big scale meadurement. With the dual direction coordinate mapping method, the accurate 3 D coordinate of the measured object can be acquired. A new image splice method based on an algorism called “flood” is ptoposed, and it can compose the whole region of the object surface with all the subregion along the optimal route.
