虚拟现实野外采集系统是通过卫星照片的三维重建技术，在计算机上利用Open GL三维显示技术再现野外三维场景，基本上可在室内进行观测系统设计，节省了野外踏勘时间。通过利用支持多种观测系统的设计方法，在进行二维、三维野外施工设计过程中，同步跟踪三维立体来显示各种统计分析结果。完成后的施工设计炮点和检波点位置图通过三维图形显示出来，能够真实地反映野外情况。通过梯度处理技术及边缘提取技术，对图像进行滤波处理，提取地形和地物信息，从而指导野外生产。

The field 3D scene can be used on computer by the Open GL software of virtual reality seismic acquisition system that uses the 3D reconstruction techniques of the satellite photograph. Observing layout can be designed indoor and much time of field exploration can be saved. By supporting various methods of layout design in 2D or 3D field acquisition, various statistical analysis results that synchronously follow 3D tridimensional figure can be shown. Finished shot-point and the geophone layout can be shown
in 3D form, which can really reflect the field situation. The image will be filtered to pick up the information of landform and surface obstacle by techniques of gradient processing and edge pick-up to guide field acquisition
