摘　　要：提出了一种全新的基于平面镜的摄像机标定方法。该方法无需任何标定物,利用平面镜的反射性质和灭点、灭线等理论,通过移动摄像机或平面镜作至少2次平移运动(各次平移间应存在旋转运动)即可线性地标定摄像机的内参数。模拟图像实验和真实图像实验表明所提出的方法能快速、方便地对摄像机进行标定,具有较好的稳定性和精度。A new method of camera calibration for intrinsic parameters is introduced in this paper.The method is based on a planar mirror and does not need any other calibration object.The intrinsic camera parameters can be linearly calibrated by using the reflection property of planar mirror and the theories such as vanishing points and vanishing lines and by controlling the camera or the mirror to undergo not less than 2 translations of which there should be rotation between any 2 translations.Both computer simulation and real data have been used to test the proposed technique and good results have been obtained.
