Abstract
A tracking system provides light source(s), a mobile communication unit and light sensor(s) with cameras, and a central control unit at least coupled to the sensor(s). The communication unit receives with its camera an identification information item broadcast by the light source(s) and broadcasts an activation signal, including data correlated with the received item, to the control unit. The control unit determines, based on the signal, at which position the communication unit is arranged and which sensor(s) is arranged relative to the position of the communication unit so that the communication unit can be detected by the camera of the sensor; activates the camera of the detected sensor(s) for providing image information by its camera to the control unit, to determine and identify a carrier of the communication unit at the determined position; and activates sensor(s) coupled to the control unit for tracking the identified carrier of the communication unit.
