Abstract: PURPOSE: A system for processing a query for a mobile object database is provided to extract various and precise information, and efficiently search the information on a platform performing an LBS(Location Based Service) and various application fields using the location information of a mobile object. CONSTITUTION: An interface(102) receives the query for the mobile objects from a location information application system(101). A query parsing component(103) parses the inputted query, and separates/parses the query contents into an attribute query and a spatiotemporal query. A mobile object location index(107) is used for efficiently searching the spatiotemporal information for the mobile object stored in the mobile object location database. A query performing component(104) extracts the attribute information of the mobile object from an attribute database through an attribute filter(105) based on a parsing result of the query parsing component, extracts the spatiotemporal information of the mobile object from the mobile object location database through a spatiotemporal filter(106), and merges the extracted attribute and spatiotemporal information.

Abstract: PURPOSE: A method for mapping texture of three dimensional topography model by using a CCD line camera is provided to perform a proper mapping of laser range data and texture image data of the CCD line camera, thereby constructing topography and earth material images having exact three dimensional information with reality. CONSTITUTION: A laser scanner(11), a CCD line camera(12), a GPS receiver(13) and an IMU equipment(14) are hardware equipment mounted to a moving body such as a vehicle. Laser scanning data of the topography, three dimensional line image, position and posture data of the CCD line camera due to the movement of the moving body are inputted to a texture mapping software(15), respectively. The texture mapping software(15) processes the input data from the laser scanner(11) and the extracts the topography model. The topography model is separated into downtown building, road, tree shape models.
