The special geometric restrictions like parallelism and perpendicularity implicated in vanishing elements are deeply studied. In single-view case,the theory is presented to interpret relationship between two planar lines by applying 3D invariants of vanishing points.
详细论述了消失元素(消失点、消失直线、消失平面等)所体现的垂直、平行等特殊几何约束关系;对单视图,提出了一种利用消失点列的3D不变量解释平面直线关系的方法;对双视图,提出了利用自共轭三角形和对极几何约束,提取任意直线的消失点的算法,并在此基础了提出了一种利用消失元素的3D不变量解释直线间、直线与平面间、平面间等多种空间几何关系的方法。
