Abstract
To realize a location-based information support system, we propose an information support system using Compact Battery-less Information Terminals (CoBITs). This system consists of the information terminals CoBITs, and many environment system units. The environmental system unit plays an important role that to send particular information to respective users, and consists of multiple cameras for estimation of the position and orientation of the terminal, and LED light sources on the controllable pan-tilt heads for sending the optical beam information. For the application for information support in an event, a method for calibration of multiple cameras and light sources which is easy to use for inexperienced persons and to setup quickly is needed. To calibrate multiple cameras and LED light sources simultaneously, we employ a calibration technique for the multiple cameras based on the self-calibration method.
