双目立体摄像机标定方法研究

本文在张正友平面模板两步法的基础上,提出了一种改进的双目立体摄像机标定方法。该方法在摄像机畸变模型中充分考虑了切向畸变的影响,使得应用范围更广。本文在标定中通过选取图像中心附近的点作为初始预测值,再进行非线性搜索来确定摄像机内外参数。实验证明,本文标定模板制作简单,标定过程快捷,且具有较高的精度,完全可以满足双目立体视觉应用的要求。

Research on Binocular Stereo Camera Calibration Method

An improved binocular stereo camera calibration approach is brought forward based on Zhang's two-stage approach in this paper.This approach takes into account the effect of tangential distortion fully and has a more widely application.This paper chooses the points near the center of images as the initial guess,and then evaluates the intrinsic parameters and extrinsic parameters of camera by nonlinear search.The experiments prove that this method has many characteristic such as simple calibration board,fast ...
