Abstract
Techniques are disclosed for determining a light-based communication (LCom) receiver position. The techniques can be used to determine the position of a receiver relative to a specific luminaire within the field of view (FOV) of the receiver camera. The relative position may be calculated by determining the distance and the orientation of the receiver relative to the luminaire. The distance relative to the luminaire may be calculated using the observed size of the luminaire in an image generated by the receiver camera, the image zoom factor, and actual geometry of the luminaire. The orientation relative to the luminaire may be determined using a fiducial associated with the luminaire that can be used as an orientation cue. Once the position of a receiver relative to a luminaire is determined, the absolute position of the receiver may be calculated using the absolute position of the luminaire.
