三维立体模型在二次设计中的应用

在石油、地质、地震等勘探部门,对于炮点的选择往往是采用地形图结合全野外测量的方法来定位。这种方法在平原地区比较适用,但在困难地区即使使用GPS也毫无办法。随着可视化技术的发展,应用计算机借助于真实三维立体,完全可以在室内进行二次设计。炮点的定位精度完全符合要求。整个设计过程全部在室内完成,外业只需进行放样工作。这项技术的应用将极大地缩短工期、节约人力、物力和财力,具有积极的现实意义。

Application of Three-Dimensional Spactial Model in Secondary Design

In departments of petroleum and geology...etc,the position of shot point was selected with topographic maps surveying with full field generally,which is suitable for plain regions,but have no ways in difficult regions even using GPS.Along with the development of visible technique,it is possible to design position in two times in the laboratory with PC and ask for help from three-dimensional model.The precision of shot point meeted with requirement completely.All the work was completed in the laboratory and the field work only needs to confirm the position of shot point.The application of this technique will greatly shorten the work time period,economized manpower,material and finance resources and also have positive and realistic meanings.
