着重解决如何将抛物面镜与普通CCD摄像机配置成满足中心投影约束的全景摄像机及其参数标定问题.首先通过数值仿真实验给出全景摄像机的配置与拟合误差之间的关系图,从而确定最佳参数配置范围.接着,研究了利用空间平面的图像信息标定抛物面镜摄像机的算法.在摄像机内参数已知情况下,借助平面诱导的单应矩阵将标定问题转化为多项式特征值问题,从而获得待标定参数的解析解,避开复杂的数值计算,达到快速标定参数的目的.结果表明,该算法最少只需5对图像匹配点便可以实现问题求解.最后,通过数值仿真实验和真实图像实验验证算法的有效性和鲁棒性.
Focusing on how to configure the parabolic mirror and ordinary CCD camera to meet the central projection constraints of the panoramic camera and its parameter calibration problem.Firstly through the numerical simulation experiment is given panoramic camera configuration and fitting error between the map to determine the best Then, the algorithm of parabolic camera calibration using space plane image information is studied.With the parameters of camera being known, the calibration problem is transformed into polynomial eigenvalue problem by plane induced homography matrix, The analytical solution of the calibration parameters avoids the complicated numerical calculation and achieves the goal of rapid calibration.The experimental results show that the algorithm can solve the problem only with a minimum of five pairs of image matching points.Finally, numerical simulation and real image experiments The Validity and Robustness of the Algorithm.
