提出了一种利用等高度垂直线段估计摄像机内外参数的自标定方法。提出了一种通过检测人体在跨腿阶段的头部和脚部位置来获取所需线段的算法。实验结果表明，该方法是准确的和鲁棒的相对于不同的视角和主题。
A self-calibration method to estimate a camera's intrinsic and extrinsic parameters from vertical line segments of the same height is presented. An algorithm to obtain the needed line segments by detecting the head and feet positions of a walking human in his leg-crossing phases is described. Experimental results show that the method is accurate and robust with respect to various viewing angles and subjects.
