Abstract

Building 3D GIS based on unprofessional images by integrating unprofessional images with current geo-information will set the trend for mainstream GIS research and applications. This paper presents a concept of unprofessional and weakly-correlated image (UWCI) as an important source of geo-information, discusses the building process of 3D GIS based on it and related key technologies, and analyzes the characters and application mode of the 3D GIS. The key technologies of UWCI-based 3D GIS are creating mapping between image space and geographical space, integration of 3D images and 3D point cloud with geo-information, and the interaction and rendering based on images and point cloud in geo-space. The UCWI-based 3D GIS can be applied to emergency response, military surveillance, rapid 3D modeling and so on.
