摘要

针对相位测量轮廓术中由光学成像设备的点扩展函数引起的卷积效应,提出了一种估计点扩展函数卷积模型参数的方法。该方法利用卷积效应对相位测量轮廓术中光强调制度参数的影响,通过计算基频与更高空间频率之间的光强调制比率,实现了对点扩展函数参数的估计,利用估计的参数建立卷积模型对误差区域进行相位校正,从而提高三维重建精度。仿真及实验结果均验证了所提方法的有效性,与校正前相比,相位的均方根误差减小了30.55%。

Abstract

The convolution effect in phase measuring profilometry, which is caused by the point spread function in optical imaging devices, is investigated, and a method for estimating the convolution parameters of the point spread function is proposed. This method can be used to assess the point spread function parameters by utilizing the influence of convolution effect on the intensity modulation parameters in phase measuring profilometry, wherein the modulation ratio of the base frequency to the other higher spatial frequency is calculated. By adopting the resulting estimated parameter, a convolution model is established for phase correction in error areas; thus, the 3D reconstruction accuracy is improved. The simulation and experimental results both verify the efficiency of the method. Compared with that obtained before correction, the root-mean-square error of phase is decreased by 30.55%.
