Development of Wheelchair Tracking System Using Omnidirectional Camera and Full Color LEDs

In this paper, a self-localization method by utilizing an omnidirectional camera and full-color LEDS is described. This method is especially useful in indoor environment in which we cannot receive GPS (Global Positioning System) radio wave. We have been developing this self-localization system to grasp the accurate position of our developed wheelchair in a nursing care facility in order to improve QoL (Quality of Life) of both patients and care givers. In this paper, we implement our self-localization system into the wheelchair and conduct experiments to verify the basic functionality of our developed self-localization system.
