Abstract

Measuring a surface geometry of an object involves capturing one or more images of the object illuminated by a light field produced by one or more luminaires having multiple pixel-layers with overlapping fields of illumination. Each pixel-layer simultaneously and in synchronization with each other displays multiple coded patterns such that combinations of the multiple coded patterns uniquely identify directions of light rays originating from the multiple pixel-layers. A unique incident light ray direction for each pixel of the captured one or more images is determined by decoding the combinations of the multiple coded patterns. The surface geometry of the object is recovered using the determined unique incident light ray direction for each pixel of the one or more captured images.
