Abstract

A method is for installing a ceiling system attached to a structural ceiling surface. The method includes illuminating, in sequence and by a projector, different subsets of a set of optical sensors separately arranged in a known distribution pattern on the structural ceiling surface. Each optical sensor of the set of optical sensors is arranged to output a temporal signal indicative of a level of illumination. The method also includes determining an image plane relative to the projector based on the known distribution pattern of the set of optical sensors and the outputted temporal signals of each of the optical sensors, and displaying, by the projector, an image indicative of installation locations of the ceiling system at the image plane.
