摘　　要：盐穴由于其良好的密封性和可塑性,在石油、天然气存储方面得到广泛的应用。盐穴三维建模可以精准获得盐穴体积,清晰地观察盐穴储存库内部空间情况,对石油、天然气的存储管理有着重要的意义。本文采用Delaunay三角剖分算法,调用开源接口VTK软件系统对声呐点云数据处理并建模,然后使用OSG软件系统对盐穴模型进行盐穴的多视口显示渲染、漫游、响应键盘鼠标事件以及红蓝立体显示等功能,实现了盐穴的可视化展示和交互操作。Salt cavern due to its good sealing and plasticity.It is widely used in oil and gas storage.Three-dimensional modeling of salt caverns can accurately obtain the volume of salt caverns and clearly observe the internal space of salt cavern storage.Salt cavern 3 d modeling is of great significance to the storage and management of petroleum and natural gas.In this paper,the Delaunay triangulation algorithm and VTK software are used to process and model the sonar point cloud data.Then,OSG software system is used in this paper to perform functions such as multi-view port display and rendering,roaming,response to keyboard and mouse events and red and blue stereo display of the salt point model.This paper realizes the visualization and interactive operation of salt cavern.
