Abstract
Apparatus for mapping an object includes an illumination assembly (30, 50), which includes a single transparency (36) containing a fixed pattern (60, 70, 80) of spots. A light source (34, 52) transilluminates the single transparency with optical radiation so as to project the pattern onto the object (28). An image capture assembly (32) captures an image of the pattern that is projected onto the object using the single transparency. A processor (24) processes the image captured by the image capture assembly so as to reconstruct a three-dimensional (3D) map of the object.

22. Apparatus for mapping an object, comprising:
-
an illumination assembly, comprising; a transparency containing a plurality of micro-lenses arranged in a non-uniform pattern; and a light source, which is configured to transilluminate the transparency with optical radiation so as to project the pattern onto the object; an image capture assembly, which is configured to capture an image of the pattern that is projected onto the object using the transparency; and a processor, which is coupled to process the image captured by the image capture assembly so as to reconstruct a three-dimensional (3D) map of the object. - View Dependent Claims (23, 24)

49. Apparatus for mapping an object, comprising:
-
an illumination assembly, comprising; a diffuser; a light source, which is configured to transilluminate the diffuser with optical radiation; a transparency containing an array of micro-lenses, which are arranged to focus the optical radiation transmitted through the diffuser, thereby generating a pattern of spots; and projection optics, which are arranged to project the pattern onto the object; an image capture assembly, which is configured to capture an image of the pattern that is projected onto the object using the transparency; and a processor, which is coupled to process the image captured by the image capture assembly so as to reconstruct a three-dimensional (3D) map of the object. - View Dependent Claims (50)
