基于OSG的OBS导航定位系统三维可视化场景实现
IMPLEMENTATION OF 3D VISUALIZATION SCENE FOR OBS NAVIGATION AND POSITIONING SYSTEM BASED ON OSG
摘要
Abstract
In marine seismic exploration, OBS navigation and positioning system can improve the OBS delivery precision.In order to organize and manage scene nodes efficiently and display movements of ship and OBS dynamically, the system uses 3D visualization technology to build OBS delivery scene based on MFC framework under the visual development environment of VS2010 and OSG 3.0.0.We use bathymetric grid data to generate terrain LOD model based on Chunked LOD, and use DatabasePager and PagedLOD technology to realize dynamic scheduling of terrain.The system achieves 3D visualization and multi-angle surveillance of OBS delivery process through roaming.It shows the seabed topography and operation process directly, and improves the OBS delivery precision and data quality.关键词
