Method and apparatus for quantitative 3-D imaging
First Claim
Patent Images
1. A single-lens device for three-dimensional imaging of a surface of an object, comprising:
- a lens;
a plurality of filtering apertures obstructing 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 of the surface;
a sensor operable for capturing the filtered information of the surface; and
a processor communicatively connected with the sensor for receiving 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.

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.

20. 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; 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 produce a surface image, the surface image being representative of the surface of the object.
