三维重建新方法及新技术研究

摘要

3D Reconstruction based on 2D engineering views is a very difficult problem in t he field of computer graphics. This dissertation advances a new style of its own by presenting a new method of 3D reconstruction aiming at practical engineer ing drawings. The new method is described as: the engineering semantics is basic , the primitive relation recognition is the precondition, the primitive recognit ion is the key, and the object composing based on the primitive relation and pri mitive is the foundation. Some new reconstruction technologies are developed: en gineering semantics processing, primitive relation recognition, primitive recogn ition and object composing.%分析了基于二维工程视图重建三维立体问题 ，以实际工程图样为重建对象， 提出三维重建新方法，即工程语义为基础，基元之间的关系识别是先导，基元识别是关键， 基元合成是根本；研制了工程语义处理、基元关系识别、基元识别、基元合成等新技术；实 现了一个三维重建原型系统，输出了以工程图样为对象的三维重建实例。
