提出了一种基于二值化调制度层析的快速在线三维测量算法.对物体调制度信息进行层析分析，有效提取反映物体形状特征的层析信息，并将该双准确度层析信息进行二值化，以该二值化层析信息为模板，进行像素匹配，可实现快速在线三维测量.为验证该算法的可行性和有效性，进行了实物测试实验，该算法与提取调制度特征区域实现像素匹配的方法进行对比测试.实验表明，该算法具有很好的测量准确度，有效地调高了测量速度.

A new method of fast on-line 3D measurement is proposed. A modulation delamination method is used to extract a token from object modulation distributions. With the token delamination information transformed into integer as the mask, the equivalent phase-shift deformed patterns at the same pixel coordinate can be realized by the pixels matching, which puts the fast on-line 3D measurement into practice. To verify its feasibility and validity, a contrast experiment on this method and a method based on a particular region of modulation distributions are carried on. Experiments show that the high-veracity of the algorithm and the speed of on-line inspection can be effectively improved.
