摘要
主要研究扫描工程图矢量化后的二维重建的有关问题。较为详细地阐述了结构约束识别模块及尺寸约束的表示,并提出了用无向有权图来表示图素间的结构约束,用权来表示图素间结构约束的类型。将尺寸约束表示模型引入到工程图纸的二维重建,从而为尺寸驱动模块的建立奠定基础。
This paper mainly concerns the 2-D reconstruction of the vectorization of scaned engineering drawing .The construction-constraints recognization model and dimension-constraints are debated in detail. The undigraph with weight to present the construction constraints between graph elements, the weight to present the class of construction-constraints between graph elements. And dimension-constraints is first introduced to 2-D reconstruction of engineering drawing. It is the base of the setup the dimension-driven model.基于矢量邻接图的剖面域识别与重建
