摘要
提出了一种新的基于主动视觉系统的摄像机自定标方法 ,其主要特点是可以线性求解摄像机的所有 5个内参数 .该方法的基本原理是利用图像中平面场景的信息 ,通过控制摄像机作多组平面正交平移运动 ,由平面场景图像的单应性 (homography)矩阵建立摄像机内参数线性约束方程组 ,来求解摄像机的内参数 。
In this paper, a new active vision based camera self calibration technique is proposed. The novelty of this new technique is that it can determine LINEARLY all the FIVE intrinsic parameters of the camera. The basic principle of our new calibration technique is to use the planar information in the scene and to control the camera to undergo several sets of orthogonal planar motions. Then, a set of linear constraints on the five intrinsic parameters is derived by means of homographies associated with scene planes.In addition,the uniqueness of the solution of the constraint set with respect to the configurations of the camera's planar motions is also investigated.
