Surround Structured Lighting for Recovering 3d Object Shape and Appearance

Disclosed are methods and apparatus for recovering the shape and appearance of an object illuminated by a coded structured light pattern that is observed by a camera, which simultaneously captures multiple views of the object. In one embodiment a Fresnel lens and a data projector are used as the means of illuminating the object with surrounding structured light patterns. The projector projects several patterns and the camera captures images of the object for each pattern. The images are decoded to determine the correspondence between projector scan-lines and camera pixels. Combined with the calibration of the relative position of the various optical elements, including the projector and camera, the ray-plane intersection is used to determine the three-dimensional depth for each part of the surface. An additional image captured under ambient illumination is used to recover the appearance for each surface point for each camera pixel.
