Abstract
An imaging system includes an optical unit that captures, from a scene, sets of first images as well as sets of second images. The scene is illuminated with non-structured light when the sets of first images are captured and illuminated with structured light when the sets of second images are captured. A pattern processing unit generates, from the second images, a recovered shadow pattern from a shadow pattern projected onto the scene during illumination with structured light, wherein at least one motion-compensated reference image is used. A depth processing unit obtains depth information on the basis of the recovered shadow pattern.
