摘要
本文提出了利用Ｍ系列编码光栅投影获取物体的三维形状的新方法。通过实验证明了本方法的有效性。本方法只需要两张图像，能够快速地获取物体形状。
A new method for measuring three dimensional shape of objects is proposed.The method projects uniformlight and a grid pattern coded in a pseudo random M-sequence on objects,and determines deformation of the grid pattern on the objects from the images by CCD camera based on the decoding of the M-sequence. The coordinates of the object points are calculated by triangulation. The validity of the method is confirmed by experiments.the advan-tages of the metbod are that it needs only two images obtained by two projections and that the decoding is not influenced by the color and/or the reflectance of objects.
