基于单幅平行六面体图的空间测量

Metrology Based on Single Parallelepiped Photo

基于单幅图像的测量是计算机视觉中一个重要的研究方向。针对平行六面体模板,本文提出了一种新的摄像机标定方法,并实现空间测量。在该方法中,利用平行六面体中的三组相互正交的平行线得到影灭点来完成摄像机的内部参数标定,进一步完成摄像机的外部标定,从而得到单应矩阵,实现了空间任意两点的测量。模拟实验和真实图像实验说明本文的方法是可行的。

Single view metrology is an important study in computer vision .Aiming at parallelepiped model, a method for camera calibration and the metrology is presented in this paper. In this method, By using three groups of crossing parallels in the parallelepiped to achieve the intrinsic parameters calibration and extrinsic parameters calibration furthermore , in the end, we can get the homography , distance between two points in the world are computed .Extensive experiments on simulated data as wells on real photos showed this approach is feasible.
