基于极线约束的多线激光条纹匹配算法

Matching algorithm of multi-line measurement of laser stripe based on epipolar constraint

依据双目视觉方法,先由双CCD摄像机摄取左右两幅标记有多线激光条纹的图像,然后对图像进行预处理.处理后的两幅图像是在不同视角下摄取的多条单像素宽的激光条纹,在极线约束的理论基础上,提出了一种多线激光条纹的匹配方法,从而实现了激光条纹的匹配和激光扫描线的三维重建.

According to two eyed vision, the left and right images are taken by two CCD cameras, then the two images are pre--processed. After being processed the two images taken at different angle of view are two pieces of multistripe laser of single pixel. A method of multistripe laser marks matching is proposed based on epipolar and continuity constraint for matching laser stripe and realizing 3D reconstruction of laser scanning line.
