| 摘 要： | 文章提出了一种基于空间三角形的摄像机标定算法.使用空间三角形作为标定物,将其绕一顶点自由转动并拍摄2幅以上标定图片,然后利用三角形三边长度信息作为约束条件建立线性方程组以求解摄像机的内参数.实验表明该算法制作标定模型简单,具有较高的精度和较好的鲁棒性.

| Abstract: | A new spatial-information-based camera calibration algorithm is presented in this paper. Spatial triangle is used as calibration object. First rotate the triangle with one vertex fixed and shot at least 2 pictures, then use edge length information to setup linear equations to compute the camera intrinsic matrix. Experiments show that our method is simple, robust, and with good precision. |
