采空区精确建模信息系统实体模型交互接口开发

随着矿业的快速发展，Surpac，Dimine，3DMine等三维矿业软件在矿业领域得到了广泛的应用。为进一步完善自主研发的采空区激光扫描三维精确建模信息系统功能，在解析stl，dxf及dtm格式文件的数据结构及其三维实体数据存储规律的基础上，成功地开发了基于上述三种实体模型存储文件格式的采空区三维实体模型交互接口，实现了信息系统与目前主流三维矿业软件之间三维实体模型的交互。实用表明，所开发的接口能有效实现信息系统与其他三维矿业软件之间采空区三维模型的交互与共享，进一步完善了信息系统的模型数据输入输出功能，提高了其应用价值。

Development of interactive interface about entity model in information system of precise modeling for goaf

With the rapid development of mining industry, the 3D mining softwares like Surpac, Dimine, 3DMine have been widely used in mining field. In order to further improve the functions of self-developed information system of 3D precise modeling by laser scanning in goaf, the data storage structures of stl, dxf and dtm file were resolved, and the data storage laws of 3D entity model in the files were summarized. On basis of that, the interactive interface of 3D entity model for goaf based on the above three file formats for entity model storage was developed, and the interaction of 3D entity model between the self-developed information system and the mainstream 3D mining software was achieved. The practical application showed that the interaction and share of 3D entity model for goaf between the self-developed information system and other 3D mining software can be achieved effectively, and the data inputting and outputting functions of model data in the self-developed information system was further improved and its application value was enhanced.
