Abstract

A method (300) for characterizing a lighting environment using thermal imaging includes the steps of: providing (310) a lighting unit (10) comprising a light source (12), a thermal imager (32), and a controller (22); obtaining (330), using the thermal imager, one or more thermal images of one or more surfaces (52) within the lighting environment; extracting (340), by the controller using the one or more thermal images, a thermal shadow (54) on one or more surfaces within the lighting environment; determining (360), from the thermal shadow, a depth queue for an object (52) associated with the thermal shadow; and characterizing (370), by the controller using the determined depth queue, the object.
