基于结构光的颜色时间编码技术研究

Study on the color time-encode technology based on structure light

介绍结构光三维视觉测量技术的基本原理,分析结构光时间编码中二进制格雷码编码解码方法,提出基于RGB颜色编码的编码方法,该方法将黑白条纹用红蓝条纹代替,用绿条纹将红兰区域分开,提取绿条纹中心得到条纹的准确定位,从而使得物体重构更准确,最后给出实验仿真结果。

The basic principle of structure light vision three dimensional technology is instructed. The article analyzes the the code and decoding principle of ordinary binary code and Gray code. Above this it puts forward a new encode method based on RGB color, Instead of black-white this method uses red-blue strip and puts one pixel green strip between red and green strip. So it can abtain more exact strip orientation through distilling the center of green strip. And the reconstruct is also more exact. The experiment simulation result is given.
