双目视觉中摄像机标定技术的研究

Research on Camera Calibration in Stereo Vision

在研究现有摄像机标定方法的基础上,提出了一种改进的平面标定法。该方法首先采用线性摄像机模型求得内外参数的初始值,然后引入径向和切向畸变,再利用非线性优化求得畸变系数。编程计算结果验证了该方法的准确性和稳定性。

This paper presents an improved plane calibration method based on studies of existing calibration method. The method used linear camera model for calculating initial interior and exterior parameters firstly, then the radial and tangent distortion were introduced, and finally, the nonlinear optimizing method was used to solve distortion coefficients. Programming calculation results verified its accuracy and stability.
