A Fast On-line 3D Measuring Algorithm Based on Two-value Modulation Delamination

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.
