摘要：基于三视图的三维实体重建技术是根据已有二维视图中的几何信息和拓扑信息,生成相应的三维实体模型。以AutoCAD绘制的三视图及DXF格式的文件信息为基础,提出并实现了一种由三视图重建三维实体的算法。通过对三视图的规则处理,由计算机自动实现实体重建,对三视图分别进行平移、旋转、拉伸操作,然后作相应的布尔运算即可反求出该视图所对应的三维实体。
Technique of 3D reconstruction based on three orthographic views refers to constructing a corresponding 3D object model by use of the geometric and topological information in the existing 2D engineering drawings.In this paper,a 3D object reconstruction algorithm from three orthographic views of engineering drawings is proposed and implemented,which is based on the information from AutoCAD orthographic views and DXF file format documents.According to the rules of projection,corresponding primitives are matched and recognized,3D reconstruction is automatically finished by computer.After 2D orthographic views are moved,revolved and extruded,the 3D object model can be reconstructed by making appropriate boolean operations at last.
