摘要
通过对Karpinsky和Zhang提出的合成相移算法的研究,消除了白噪声,将相同参数条件下的面形重建精度提高了1倍。在虚拟结构光投影的基础上,提出了两种用彩色图像压缩记录三维面形信息的算法;双通道相位编码算法,提高了压缩比;三通道相位编码算法,能够同时提高压缩比和面形重建精度。给出了算法面形重建精度的定量分析,并指出PNG格式为较好的无损存储方式。
Abstract
After studying the composite phase-shifting algorithm for 3D shape compression, two novel methods two-channel phase encoding algorithm and three-channel phase encoding algorithm are proposed. They can improve the compress ratio and the reconstruction quality by storing the 3D shape data into two or three channels of a 24 bit color image. Computer experiments and quantitative analysis provide a guide to achieve appropriate reconstruction quality and compression ratio.
