摘要
提出了一种新的可变焦相机的标定方法。它采用至少6个已知空间点用最小二乘获取投影矩阵的最优解,在计算投影矩阵的基础上,利用旋转矩阵的正交性和摄像机参数之间的约束关系,用单幅图像即可实现摄像机内外参数的恢复。模拟和真实实验结果均表明了本文算法的可行性和鲁棒性。
A novel calibration method of camera with variable focal length is proposed. By means of using the orthogonal rotation matrix and constraints among camera parameters in the single-view vision, a new algorithm to linearly and exactly calibrate the camera from single-view at least six known feature points is developed. Both simulation and true image experiments prove the feasibility and robustness of this algorithm.
