摘    要:提出一种新颖的基于工程图样理解的三维形体重建方法,设计了完整的算法,并建立了一个原型系统。文中的研究成果在三个方面取得了较大的进展:1)将重建对象从一般图形拓展到含半剖视图、全剖视图和尺寸标注的工程图样,使三维重建的实用化成为可能;2)较好地利用了工程图样语义进行形体分析,实施图形预处理,降低了特征识别的难度;3)将特征识别与三维重建结合起来,使重建结果包含形体信息,为利用重建结果进行更高层次的工

关 键 词:工程图样  三维重建  特征  语义  预处理

Abstract:A novel 3D reconstruction method based on engineering drawing understanding is presented. A series of algorithms are set up. First, reconstruction processes are extended to engineering drawings containing semi section or full section views. Second, feature recognition is made easier by analyzing the structure and semantics of engineering drawings. Third, 3D reconstruction is carried out together with feature recognition so that the reconstruction result can be further processed at a high level of intelligence.
Keywords:engineering drawings  3D reconstruction  feature  semantics  pre  processing
