【摘要】 论文提出了一种基于分层重建的摄像机完全自标定方法。该方法不需要摄像机在运动中存在纯平移或者纯旋转运动等特定的运动,只需要摄像机按任意的运动拍摄三幅图像进行射影重建,然后通过在分层重建中引入cheirality约束确定无穷远平面的搜索范围,以完成摄像机内参数的标定。实验结果证实本文提出的方法比以两幅图像为几何约束的方法具有更好的鲁棒性和准确性。更多还原

【Abstract】 This paper proposed a method of camera self-calibration based on stratified reconstruction.This method doesn’t need camera to do specific movements,such as flat-screen move motion,pure rotation movement,and so on.Just need a hand-hold camera arbitrarily to shoot a few images.First,we obtain the projective reconstruction of the object,and then, introduce cheirality constraint in stratified reconstruction to determine the search area of the infinity plane,and finally achieve the camera intrinsic parameters calibration..Experiment results prove the feasibility and accuracy of this method.更多还原
