A study on processing of position detection and data communication using illuminant devices and image sensor

Using light sources and an image sensor, we have proposed a system which emulates wireless data communication and position detection simultaneously. Here, the light sources are installed as a transmitter on a target side, and the image sensor as a receiver on an observer side. The detection of flashing light sources leads to wireless data communication from the target to the observer. While the image sensor is capturing the multiple light source, the target's position can be computed by means of the image measurement. The advantages of this system are as follows; (1) both of position detection and wireless data communication can be processed simultaneously, (2) the system can be used at the place where any radio wave is prohibited, or where strong electromagnetic noise is emitted.
