基于先验知识的图纸转换技术研究

Research on DWG Drawing Conversion Technology Based on Prior Knowledge

目前电网一次设备接线图多为DWG格式,这种文件在编辑和浏览中都需要CAD软件支持,因而使图纸的应用范围受到了影响。为了保证转换后图纸在图形和语义上与原有图纸保持一致,提出了一种基于识别重绘的图纸转换算法。通过识别建立图纸的层次拓扑结构,可以准确地实现DWG图纸到SVG图纸转换,保证了对历史图纸资源的继承与使用。

At present, most of the grid wiring diagram of equipment for the DWG format, this file editing and browsing need CAD software support, so that the application of the scope of the drawings have been affected. In order to ensure that the drawings after translation are consistent with the original drawings in the graphics and semantics, a paper conversion algorithm based on recognition redrawing is proposed. By recognizing the hierarchical topology of the drawing, the DWG drawing to SVG drawing conversion can be realized accurately and the inheritance and use of historical drawing resources can be ensured.
