| 摘 要： | 三维传感系统中,二元误差扩散编码光栅可应用于产生质量较好的正弦结构光场.光学系统的低通滤波窗口成为影响系统测量精度的因素之一.比较了3种常见滤波函数,分析各自特点.计算机仿真实验表明,应用二元误差扩散编码光栅,采用高斯窗、汉宁窗或矩形窗作为PMP系统滤波窗口时,系统测量精度为同一量级,且窗口宽度取6倍光栅基频最佳.

| Abstract: | Binary Error Diffusion Gratings can be used in Three-dimensional(3-D) sensing systems in order to obtain sinusoidal structure illumination with good quality.The low-pass filter function of the optical system can be one of the factors which effect the system measuring accuracy.Three kinds of common filter function are compared in this paper.Computer simulation shows that the PMP system measuring accuracy will be of the same magnitude with three kinds of filter window,that is,gauss,hanning or rectangle window... |
