Abstract

This paper mainly describes an orientation control scheme of a vision-based autonomous vehicle by means of fluorescent lamps on the ceiling. The long shape of a fluorescent lamp makes this control possible. First, we propose the method that discriminates a fluorescent lamp from the other light sources and gives the distance and the angle between the vehicle and the fluorescent lamp. Then, the errors of the detected distance and angle are estimated and it is found that they are small enough to control the vehicle. Lastly, experimental results of the vehicle navigation are shown. The vehicle can move along the fluorescent lamp array or in a certain direction from the fluorescent lamp array. These two types of vehicle motion give the autonomous vehicle more flexibility to decide the vehicle's path in factories.
