提出了一种新的高精度的摄象机光学参数及几何参数的标定方法，利用透视变换理论建立了摄象机数学模型，首先用牛顿高斯非线性搜索方法求解摄象机畸变系数和一个中间矩阵，然后从中间矩阵中分离出其它模型参数；为解决非线性搜索的初值问题，采用线性化方法、简单迭代法求得中间矩阵的初值。理论及实际应用表明，该标定方法速度快、精度高。
A new high precision method for calibrating the optical parameters and geometrical parameters of the camera is proposed. The mathematical model of the camera is established by using perspective transformation theory. First, the Newton-Gaussian nonlinear search method is used to solve the camera distortion coefficient and a Intermediate matrix, and then separate the other model parameters from the intermediate matrix. To solve the initial value problem of nonlinear search, the initial value of the intermediate matrix is obtained by using the linearization method and the simple iteration method. Theoretical and practical applications show that the calibration method is fast and accurate.
