摘要
利用引水发电系统的平面布置与纵剖面CAD图,探讨了如何从平面图形中提取所隐含的三维信息。提出了图形分层、分色处理的基本思想与处理方法,包括对管道中心线及管道断面图层的命名规定、管道中心线交替颜色设置等。详细阐述了管道的编码规则、断面数据获取方法,以及经数据匹配生成三维构造所需几何与拓扑信息的基本原理。在KerenCAD图形系统中实现了水电站引水管道的三维重构。
By using CAD drawings of floor chart and sectional drawings of pilot power-generation system, the matter of how to extract the 3D information hidden in the 2D drawings is explored. The basic idea and processing method are put forward including naming rules for center-line and section layer of pipelines, and alternate color setting of pipeline center-line. The ways of acquiring sectional data, the rules of encoding, and the basic principle of forming 3D topology and geometry information are also described. The regenerating 3D model of pipeline system is realized in KerenCAD.
