Abstract
A device and method for self-localization of a ceiling-mounted device within an indoor environment includes establishing a floor plan of the environment including a plurality of fixed reference indicia having known locations with respect to an origin point of the environment. A plumb light beam is projecting downward from the device to a floor of the environment to produce a projection on the floor. An imaging of the floor including the projection and at least two reference indicia is captured. A location of the device can then be determined with respect to the origin using the projection and at least two reference indicia.
