1. Apparatus for mapping an object, comprising:
- an illumination assembly, comprising;
a single transparency containing a fixed pattern of spots; and
a light source, which is configured to transilluminate the single 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 single 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.

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

11. Apparatus for mapping an object, comprising:
-
an illumination assembly, comprising; a transparency containing an uncorrelated pattern of spots; and a light source, which is configured to transilluminate the transparency with optical radiation so as to project the uncorrelated pattern onto the object; an image capture assembly, which is configured to capture an image of the uncorrelated pattern that is projected onto the object; 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 (12, 13, 14, 15, 16, 17, 18, 19)
