An algorithm for laser stripe matching based on the epipolar constraint

摘要: 提出了一种基于极线约束的激光条纹匹配算法.先通过双CCD摄像机摄取左右两幅图像,然后对图像进行预处理.处理之后的两幅图像是在不同视角下摄取的两条单像素宽的激光条纹,在极线约束和连续性约束的理论基础上,提出了一种直线和曲线求交的匹配方法,从而实现了激光条纹的快速精确匹配和激光扫描线的三维重建.

Abstract: An algorithm for laser stripe matching based on the epipolar constraint is presented.First,the left and right image are taken by CCD camera,then the two images are pre-processed.After being processed the two images that are taken at different angle of view are two pieces of laser stripe of single pixel.A method to solve the point of curve and line matching is proposed based on epipolar and continuity constraint,which ensures that fast precise matching of laser stripe and 3D reconstruction of laser scanning line can be realized.
