Projection algorithm for laser three dimensional measurement

在三维激光测量系统中,投影算法的研究和改进具有很重要的实际意义。本文首先分析了标准投影算法的原理,进行了理论公式的推导。同时,为了满足对更高性能算法的要求,在标准投影算法的不足的基础上,提出了全网格线性投影算法。通过对全网格线性投影算法原理和公式推导,可以发现全网格线性投影算法不但具有更高精度和速度,而且具有更强的自适应性和鲁棒性。本文给出了其原理和全部公式的推导,并完成了实验,给出了使用全网格线性投影法得出的实际三维扫描图像,得到了满意的结果。

The study and improvement of projection algorithm have important practical meaning in the three dimensional measurement systems. In order to achieve higher performance, the grid linear projection was proposed based on the analysis of the principle and the disadvantage of the standard projection method. The grid linear projection showed not only higher precision and speed but also better self-adapting in theoretical analysis. The principle and all of the formulas of grid projection were given, the experiment was done, and some practical scanned 3D images obtained by grid linear projection method were given as examples. The experimental results approve of the theoretical conclusion.
