摘　　要：在Sugihara方法的基础上提出一种计算机自动解释工程物体线图的迭代方法。该方法根据线图中隐含的几何元素间的约束关系,从有误差的工程物体画隐线图恢复平面立体的三维参数,并对画隐线图中有误差的节点位置进行校正,使得修正后的线图是一个工程物体的投影线图,并且尽量和原输入线图一致。实验结果表明该方法是有效的。A new iterative approach for automatic interpreting line drawing of objects in engineering is provided. The method is based on Sugihara＇s algorithm. Models of objects are reconstructed from a single line drawing with noise by using iterating technology, and the line drawings with noise are corrected at the same time. Two experiments are accomplished by using image and line drawing. The results show that our algorithm is effective.
