1. A single-lens device for three-dimensional imaging of a surface of an object, comprising:
- a lens;
a plurality of filtering apertures obstructing an optical path including the lens and configured such that light that is reflected from a surface of an object passes through the lens and the filtering apertures and is filtered to become filtered information indicative of the surface;
a sensor, along said optical path and operable for capturing the filtered information indicative of the surface and producing an output signal indicative thereof; and
a processor communicatively connected with the sensor for receiving the output signal indicative of the filtered information of the surface from the sensor and further configured to produce a surface image, the surface image being representative of the surface of the object, wherein said processor detects a deformed pattern from the surface, where said deformed pattern has been deformed by the surface, compares said pattern that is detected from the surface with information indicative of an original pattern prior to being deformed by the surface, and where said surface image is determined by both defocused information and also by finding, differences between the original pattern and the deformed pattern.

Abstract
Described is a method and apparatus for obtaining additional information from an object and a method for surface imaging and three-dimensional imaging. Single lens, single aperture, single sensor system and stereo optic systems are enhanced via selective filtering, use of defocusing information, use of an addressable pattern, image matching, and combinations thereof.

-
a lens; a plurality of filtering apertures obstructing an optical path including the lens and configured such that light that is reflected from a surface of an object passes through the lens and the filtering apertures and is filtered to become filtered information indicative of the object surface; an addressable pattern for placing addressable pattern information on the surface of the object; a sensor, along said optical path and operable for capturing the filtered information and addressable pattern information indicative of the object surface and producing an output signal indicative thereof; and a processor communicatively connected with the sensor for receiving the output signal indicative of the filtered information of the surface from the sensor and further configured to produce a surface image, the surface image being representative of the surface of the object, wherein said processor detects a deformed pattern from the surface, where said deformed pattern has been deformed by the surface, compares said pattern that is detected from the surface with information indicative of an original pattern prior to being deformed by the surface, and where said surface image is determined by both defocused information and also by finding differences between the original pattern and the deformed pattern. - View Dependent Claims (23, 24, 25, 26, 27)

28. A single-lens device for three dimensional imaging of the surface of an object comprising:
-
a lens; a first color filtering aperture and a second color filtering aperture configured such that light that is reflected from a surface of an object passes through the first color filtering aperture and the second color filtering aperture and is filtered to become filtered information of the object surface; an addressable pattern projector configured to project an addressable pattern for placing addressable pattern information on the surface of the object, wherein said pattern has one part that is distinguishable from other parts of the pattern, forming a reference for said addressable pattern; a sensor operable for capturing the filtered information and addressable pattern information of the object surface; and a processor communicatively connected with the sensor for receiving the filtered information of the surface from the sensor and further configured to assign an address to each of a series of points on said deformed pattern based on at least a portion of the addressable pattern information relative to said reference and at least one point representing at least one aspect of the object to produce a surface image, the surface image being representative of the surface of the object. - View Dependent Claims (29)
