摘　　要：本文提出了一种基于点与直线关系从正轴测画隐线图来建立平面立体线框模型的新方法。给出了基于点线关系的基本约束,根据正轴测画隐线图中隐含的点与直线位置关系建立约束方程和一个线性系统,通过求解该线性系统,得到了平面立体的三维信息。该方法适用于重构平面立体的正轴测画隐线图。并用算例进行了验证。This paper proposes a new method of building up planar three-dimenaional wire-frame model by orthoaxis hidden-part-drawn line drawing based on lines and points. It also provides the basic constraining towards relationships of lines and points. A constrant equation and a linear system shall be built in accordance with the relationships in the orthoaxis hidden-part-drawn line drawing. Then, the theorems will be wtilized to obtain the planar three-dimensional information. Finally two illustrative examples will be demonstrated to show preliminarily that the new method is feasible and effective.
