摘　　要：提出了一种基于单相机三维重建的简单方法.在待重建场景中放置一块平面标定模板,用内参数已知的摄像机拍摄不同角度的二幅图像,利用场景中的标定模板精确地求解出拍摄时摄像机的外参数,并以此为基础进行立体标定、配准和匹配,得到视差图进而实现欧式几何意义下的三维重建.实验结果表明,提出的算法实现简单、配置灵活,具有较强的实用性.This paper presents a simple 3D reconstruction method based on single camera. A planar pattern is placed in the scene to be 3D reconstructed. Two or more pictures are taken by a single camera which intrinsic parameters were calibrated beforehand. And the extrinsic parameters are calculated accurately using the planar pattern. Standard stereo steps such as stereo calibration, rectification, matching and triangular are then performed. Experimental results show that the proposed method is simple, flexible and effective.
