| Abstract: | 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. |
