Abstract
A projection assembly for use with an unmanned aerial vehicle (UAV) such as quadrotors. The projection assembly includes a projection screen with a rear surface and a front surface, and the projection screen has a level of opacity and/or other physical qualities that enables it to function as a rear-projection surface. The projection assembly includes a vehicle attachment member adapted for coupling with a frame of the UAV, and the projection screen is supported at a first end by the vehicle attachment member. The apparatus includes a projector projecting light, and the projected light is directed onto the rear surface of the projection surface to generate a displayed image visible on the front surface. The projection screen can be formed from a mesh sheet with a porosity allowing air to flow through the projection screen. The mesh sheet may be formed of plastic threads that provide the rear-projection surface function.
