Abstract

See full text

A depth value is measured. An image is captured of an object illuminated by one or more light patterns effected by multiple pixel-layers. Each pixel-layer includes an array of pixels. A direction of incoming illumination is determined for a specular reflection at a point on the surface of the object. The depth value of the point on the surface of the object is determined based on the captured image and the direction of incoming illumination.
