摘要
本文详细介绍了依据条纹反射术测量镜面、类镜面的原理和方法,分析了经由梯度数据重建三维面形的主要算法和关键问题。通过计算机模拟和波面实际测量,对十字路径积分法、傅里叶变换积分法和区域波前重构法三种主要算法的重建精度进行了对比研究。研究表明:区域波前重构法不但对高频噪声有较强的抑制作用,同时也可以处理复杂的连通区域和非等间距分布梯度数据的复杂情况,因此更适用于基于条纹反射术的波面测量。
Abstract
The measurement principle for specular and mirror-like surface was discussed and the main algorithms and key points for shape reconstruction via gradient data were analyzed in general.The simulation and the experiment results demonstrated the precision of cross path integration techniques,Fourier transform integration and area wave-front reconstruction method.And the results prove that the area wave-front reconstruction method is not only very immune to high frequency noise,but also has excellent performance when dealing with complicated multi-connectivity surface and non-grid gradient data,which is more suitable for wave-front detection based on fringe reflection.
