Content-based Virtual Geography Scene Retrieval and Intelligent Navigation

该文提出和探讨了基于内容的虚拟地理场景检索与智能导航研究框架。该框架包括三维地理数据获取与模型创建 ,三维地理对象的识别与定位 ,三维地理场景的内容分析、检索与认知 ,基于内容的虚拟地理数据层次式描述与分类索引 ,地理场景智能导航以及基于内容的自适应虚拟地理数据网络传输等方面的研究方法和内容 ,有助于建立一种符合人类认知特点的人地关系和人地交互模型。最后 ,总结和分析了该技术在虚拟地理环境 (VGE)研究中的地位和作用。

This paper proposes a research framework of Content-based Virtual Geography Scene Retrieval and Intelligent Navigation, which includes 3D geography data acquisition and modeling, 3D object recognition and localization, content-based analysis, retrieval and perception of 3D geography scene, content-based data hierarchy and indices of virtual geography environment, intelligent navigation and self-adaptive data transmission on network. This research will contribute to establish a novel model of human-geography relationship and interaction according with human perception. At last, the promising directions and potential applications in Virtual Geography Environment caused by this research are also summarized.
