Realization of CAD interface in 3D modeling visualized integrated system of cavity's laser detection

根据自主研发的采空区激光探测三维建模可视化集成系统的功能,研究CAD通用dxf格式文件的数据储存特征,开发系统数据的CAD接口,实现由系统输出的采空区三维点云模型、空区剖面、三角网格实体模型和扫描线三维实体模型dxf文件的自动生成。研究结果表明:接口的研发不仅能够很好地实现集成系统与Auto CAD之间的数据对接,为矿山开展采空区周边相关开采工程设计带来极大的方便,而且能为其他CAD接口技术的研发提供借鉴。

In order to satisfy the functional requirements of the cavity＇s 3D modeling integrated system, the data storage characteristics of dxf file used universally by CAD were researched. The CAD interface of system data was developed. The dxf files about cavity＇s point cloud model, profile, triangular mesh entity model and entity model based on scanning strips created by the system were generated automatically. The results show that the data sharing between integrated systems and AutoCAD can be realized through this interface, and great conveniences can be brought by the interface in the works surrounding cavity such as relevant mining design, which provides useful reference for designing the CAD interface.
