| 摘 要： | 该文提出一种新的由三视图重建三维实体的算法,能扩展自顶向下的三维重建算法的形体覆盖域,并在Auto-CAD平台上验证了算法的有效性。算法的主要步骤是首先用平扫-旋转-求交的实体运算法则构造出与所求实体形状相近的实体———第1参照体,再模拟人脑的识图过程:把第1参照体的三视图与初始三视图对比,根据两者之间的差别构造出差异体,再从第1参照体中逐一减去差异体,得到第2参照体、第3参照体......最后得到所求的实体。

| Abstract: | A novel algorithm which is called Approach Based Algorithm,is proposed to reconstruct3D solid from2D views.Firstly,a similar solid is reconstructed by sweep and intersection.Then some sub solids are reconstructed by comparing the views of the similar solid and that of the result solid.Finally,by subtracting these sub solids from the similar solid one by one,people can get the result solid.This algorithm can reconstruct more kinds of solids than the conventional algorithms. |
