立体视差测距中摄像机参数的一种测定方法

A Camera Calibration Method for Stereoscopic Disparity Metrology

本文提出了一种摄像机参数的测定方法，该方法利用已知实际相对位置的几个物点的左右两幅图像，根据投影几何学的定理确定摄像机参数的初值，通过最小二乘方估计和逐步逼近的方法算出满足精度要求的摄像机参数．

A camera calibration method for stereoscopic disparity metrology is described and discussed. It uses stereoscopic images of same objects with known position as input. Based on the projective geometry,and initial estimate of camera parameters is determined,and then the accurate estimate of camera parameters is computed by an iterated algorithm using the least square method.
