Indoor positioning system for automatic wheelchair control

Nowadays, Global Positioning System or GPS has been used extensively in various applications such as navigating to the target location, tracking the movement of people, security monitoring and determining point to relieve public disasters. Applications in healthcare smart home are discussed in this paper. We develop an indoor GPS for wheelchair patient who suffers from paralyze or semi-paralyze condition. Our propose system consists of a series of digital camera installed on the room ceiling. The captured room images are sent to the server. The image are enhanced and stitched to form the whole room image. The location of wheelchair moving in any camera is detected. The coordinate is computed and transmitted to the wheelchair motion control to determine the direction and possible pathway.
