摘要
基于张正友摄像机标定算法,从棋盘空间平面与像方平面的单应性关系出发,首先利用最小二乘方法解算单应性矩阵,然后通过单应性矩阵基本约束条件推导出两个约束方程,从而进行线性与非线性方式解算摄像机内参数。最后采用实际图像数据进行实验,验证了线性与非线性两种解算方法的可行性。
Based on the camera calibration algorithm proposed by Zhengyou Zhang,we firstly calculate the holography between image plane and space plane of the chessboard by way of the least square method.In the next step,two constraints equations are derived by two fundamental constraints of the holography.On the basis of the given equations,we work out the camera intrinsic parameters through linear and nonlinear solver methods,whose feasibility can be verified by experiments with real data.
