A New Method of Determining the Relative Position of Stereo Crest Line to Projective Plane

根据空间几何元素直线、平面所具有的方向性 ,找出相交两平面与其交线之间方向性的内在规律 。

According to the directionality of space geometric element staight line and the phane,the inherent law of directionality between the two intersecting planes and it's concurrent line is found in this paper.A new method of determining the relative position of stereo crest line to projective plane is also put forward.
