扫描工程图二维重建中基于图表达的结构约束校正

Graph Expression Based Construction Constraint Correction in the 2-D Reconstruction of Scanned Engineering Drawings

本文主要研究扫描工程图二维重建中图素间拓扑关系的识别和表达 ,建立了“无向有权图”的图素拓扑关系表达模型 ,并给出了相应的算法和基于该模型的实验结果。

The paper mainly focuses on the recognition and presentation of topologic relations between elements of scanned engineering drawings,sets up the model of 'undigraph with weight' to present the relations,and gives the corresponding algorithms and the experimental results based on the model.The building of the model is the basis to finally realize the size driven 2 D reconstruction of scanned engineering drawings.
