提出一种基于数字莫尔的三维光学数字成像系统。此系统采用了非相干光投影和空间相移算法以及混合模板相位复原技术来重构连续位相分布图。给出一种光学几何灵敏度的确定方法并由此获得空间自由表面的三维数字图像。文中还给出由该光学数字化系统得到的真实人体面部的三维数字图像的实验结果。
A digital Moir-based three-dimensional optical digital imaging system is proposed. The system uses incoherent light projection and spatial phase shift algorithm as well as hybrid template phase recovery technique to reconstruct the continuous phase profile. A method of determining optical geometrical sensitivity is given and a three-dimensional digital image of the free-space surface is obtained. The experimental results of a three-dimensional digital image of a real human face obtained by the optical digitization system are also given.
