Design of MMS (Mobile Mapping Systems) applicable to LBS (Local Based Services)

The mobile mapping system using the vehicle equipped the GPS, IMU, CCD Camera is the effective system for the management of the road facilities, update of the digital map, and etc. If the geographic information which is acquired by the mobile mapping system can be transmitted in real-time, users can process what they want using latest data. We have developed a prototype image recognition system capable of identifying landmark (typically, city buildings and structures) from photographs captured on camera phones. The image recognition process runs server-side, as a Web service accessible over GPRS from a Web enabled phone or PDA. Photographs of landmarks are preloaded into a central database, which is then queried by users submitting images from their camera phones. The image recognition algorithm is robust to variations in both illumination and point of view. In this paper, the effective method was suggested for the transmission of the geographic information acquired by camera attached to a PDA such as position data, altitude data, and image data in the wireless Internet environment in real-time.
