摘　　要：如何拼接好多幅投影栅线图的测量数据 ,是测量回转物体表面形状的关键 .本文提出一种新的基于柱坐标变换的数据拼接方法 ,推导出了相应的公式 ,给出了具体的操作步骤 ,并进行了实验验证 .How to combine the measured data of grating projected patterns is a key factor in measuring 3D topography of revolving objects. A new data combination method, which is based on cylinder coordinate transform, is proposed in this paper. The equations and operating steps are introduced and the experiments are given. All the projected gratings patterns are processed by FFT phase technique.
