| Research Abstract |
The management of spatio-temporal data is becoming increasingly important in many application fields such as Computer-Aided Design (CAD), Geographic Information Systems(GlS) and Virtual Reality(VR) systems, because capturing data on moving objects has become easier by the development of GPS and PDA.
The head investigator and his colleagues have been studying on the efficient spatio-temporal data management method based on tree structure. In this research, we have developed a new data management system for moving objects and investigated its application. The contents of our research include the following items.
1) Spatio-temporal data management structure
2) Data management system for camera
3) Information filtering
