基于主动视觉摄像机标定方法

基于主动视觉的摄像机标定是摄像机标定的重要分支之一，本文引入了必要的基础知识和概念，诸如摄像机模型和投影矩阵，基础矩阵，单应矩阵，极点，FOE（Focus Of Expansion）等，还对基于摄像机纯旋转的标定，于摄像机三正交平移运动的标定，基于多次摄像机平面正交运动的标定，基于无穷远平面单应矩阵的标定以及于射影重建的标定进行了评述并给出了结论。

A Review on Some Active Vision Based Camera Calibration Techniques

The active vision based camera calibration is one of most important research directions in camera calibration. This paper reviews some of the techniques reported in the literature recently in the field. The paper is organized as follows : Section 1 is a brief introduction. Some basic concepts are listed in Section 2, such as camera model, projection matrix, fundamental matrix, infinite homograpgy, epipole, FOE (Focus Of Expansion). The calibration of a rotating camera is reviewed in section 3. Camera calibration via three mutually orthogonal camera motions is reviewed in section 4. Camera calibration by multiple planar orthogonal camera motions is reviewed in section 5. Section 6 is about camera calibration by the infinite homography. The camera calibration through projective reconstruction is discussed in section 7. Finally some concluding remarks are given in section 8.
