Patent ID: 8730320

Claim:
A lighting apparatus that projects irradiation light toward an irradiation target object having an arbitrary shape, comprising: a memory storing an irradiation light signal inputting receiver, a coating corrector, an irradiation light generator, a coating corrector input interface; plurality of irradiation light projectors configured to project the irradiation light onto the irradiation target object; the irradiation light signal inputting receiver configured to receive an irradiation light signal; the coating corrector configured to correct the irradiation light signal received by the irradiation light signal inputting receiver so that the irradiation target object can be coated with the irradiation light when the irradiation light is irradiated onto the irradiation target object( ); and the irradiation light generator configured to generate irradiation light by using the irradiation light corrected by the coating corrector, and projecting the irradiation light from the plurality of irradiation light projectors; and the coating corrector input interface that enables the coating corrector to acquire a target object parameter, including a three-dimensional shape, position, and posture of the irradiation target object, and that enables the coating corrector to acquire an irradiation light projection parameter, including a position and posture of each of the plurality of irradiation light projectors, which enables the irradiation light generator to generate a coating light for projection only onto the irradiation target object and to generate a background light for projection only onto a region other than the irradiation target object, wherein the coating corrector includes a first irradiation fight signal corrector configured to correct the irradiation fight signal for each of the plurality of irradiation fight projectors in accordance with an outline of the irradiation target object, and to correct the irradiation fight signal so as to coat the irradiation target object in many directions with the irradiation fight irradiated from the plurality of irradiation fight projectors, the outline being viewed from each of the plurality of irradiation fight projectors and based on an irradiation target object parameter including a three-dimensional shape, position and posture of the irradiation target object and on an irradiation fight projection parameter including a position and posture of each of the plurality of irradiation fight projectors, and the irradiation fight generator generates plural pieces of the irradiation fight by using the irradiation fight signal for each of the plurality of irradiation fight projectors, the irradiation fight signal being corrected by the first irradiation fight signal corrector.
