摘要
三维景观重建是虚拟现实地理信息系统 (VR GIS)研究中的重要方向之一。为探索海量地质数据的处理 ,提出了基于体数据的三维地质景观重建算法 ,并实现了体数据的快速拼接 ,解决了微机环境下大范围地质景观的快速重建问题。最后结合实际数据 ,分析和讨论了三维地质景观重建技术。给出了相应的算法、技术流程和图例。
The three dimensional landscape reconstruction is one of the important aspects in the research of Virtual Reality Geographic Information System(VR-GIS). In order to explore the processing of Gigabytes geology data, the 3D-landscape reconstruction algorithm based on volumetric data is presented. And the quick reconstruction problem of large scope of geology landscape under the microcomputer environment is resolved. At last, the 3D geology landscape reconstruction technology is analyzed and discussed in combination with the practical data. The corresponding algorithm, technical flow chart and legend are presented in this paper.
