| 摘 要： | 本文提出一种利用单个透视投影识别空间多边形的方法.空间多边形的识别依据于在透视投影下的基本不变量:交比.提出了使用交比描绘多边形的形状.该描绘子的基本特点具有在透视投影下观点不变性质,因此这种方法可直接应用到机器人视觉技术中.

| Abstract: | An approach to planar polygon recognition from single 2D perspective projections using the basic viewpoint invariant called Cross-Ratio is presented. The CR-Descri-ptor of the shape of planar polygon, i.e., the Cross-Ratio sequence extracted from its single projective image is introduced. The recognition depends on minimum square criterion The approach can be directly applied to the recognition and motion matching of the 3D objects that contain the planar polygons. |
