Abstract:
A 3D digital indoor localization system uses light emitting diode (LED) lighting infrastructures for localization. In one example approach, a light source includes a convex lens and an array of LEDs, all configured as a single LED lamp. The localization system exploits the light splitting properties of the convex lens to create a one-to-one mapping between a location and the set of orthogonal digital light signals received from particular LEDs of the LED lamp.
