Simultaneous processing of target detection and data communication

Instead of radio waves, light sources are used for the position detection and the communication in our proposed system. In the system, light sources as a transmitter are attached on a target object, and the image is detected by an image sensor as a receiver. Once the image sensor captures the image of the lights, it is possible to compute the position of the object based on the image processing of the light images. At the same time, the communication data can be transferred with the flashing of lights. The advantages of this system are as follows: 1) both the position detection and the communication can be processed simultaneously; 2) the system can be used at places where the use of radio waves are prohibited.
