Description: 极点、 极线是射影几何中一个极其重要的概念。建立在极点、 极线基础之上的立体视觉技
术又是计算机视觉中非常活跃的一个研究领域。利用图像坐标计算极点、 极线 ,当图像坐标很大
时 ,就会引起计算精度的下降 利用齐次坐标来计算极点、 极线 ,相应地增加计算量。本文从实际计
算的角度出发,使用 N矢量来表示视平面上的点和直线,由二次曲线极点、 极线的定义给出了极点、
极线的 N矢量计算公式。 在此基础上,给出了正交准则的 N矢量判定公式。通过举例分析和实验验
证 ,该算法实用、 可靠。-Poles and polar lines are the most i mportant concep ts in p r ojective geometry . The computati on by using
