Abstract: The disclosure provides for a system of markers and methods of using the system of markers to provide a precise scene scale reference for captured aerial images. Each of the markers may include one or more pairs of aligned collimated light emitters, where each pair of light emitters is configured to emit two light beams that converge at a known distance from the marker. When two or more markers are used, the system of markers may be aligned in a unique physical orientation to form a shape of known dimensions (e.g., a line, a triangle, or square) that provides an accurate scene scale reference for captured images.

Abstract: A pixel projection component for projecting a multi-vantage point light-field includes a distal layer with a plurality of apertures disposed therein, each of the plurality of apertures traversing the distal layer between a convex outer surface and a concave inner surface, and an intermediate layer comprising a plurality of light guides, the intermediate layer being mechanically coupled to the distal layer such that a proximal end of each light guide of the plurality of light guides is oriented to accept light transmissions from a corresponding light source and a distal end of each light guide is oriented to transmit the light transmission through a corresponding aperture of the plurality of apertures, such that the light is directed to targeted vantage points corresponding to the corresponding aperture, and causing different light transmissions to be transmitted to different vantage points.
