Abstract

Abstract: Based on properties of image point satisfying certain linear equations and the distance between adjacent image points being equal，this paper corrects the calibration template image，and uses the improved Zhang Zhengyou calibration method，a new nonlinear camera calibration method is put forward using the corrected template.Compared with the existing methods，this method can achieve higher accuracy of camera calibration，stronger robustness，and can greatly reduce the complexity of the algorithm.

Key words: camera calibration, lens distortion, calibration template, distortion correction, robustness

摘要： 基于图像点满足的特定直线方程以及相邻图像点之间距离相等的性质，对标定模板图像进行校正，并通过改进的张正友标定法，提出了一种新的使用校正模板的非线性摄像机标定方法。与现存的方法进行比较发现，该方法能够实现较高精度的摄像机标定，鲁棒性比较强，且能够大大地降低算法的复杂度。
