Single-lens, single-aperture, single-sensor 3-D imaging device
First Claim
1. A device for three-dimensional (3-D) imaging comprising:
- a lens;
a substantially oblong aperture obstructing the lens, said oblong aperture having an oblong shape;
a sensor operable for capturing electromagnetic radiation transmitted from an object through the lens and the substantially oblong aperture; and
a processor communicatively connected with the sensor for processing the sensor information and producing a 3-D image of the object based on a distance between edges of said oblong shape determined by said sensor.

Abstract
A device and method for three-dimensional (3-D) imaging using a defocusing technique is disclosed. The device comprises a lens having a substantially oblong aperture, a sensor operable for capturing light transmitted from an object through the lens and the substantially oblong aperture, and a processor communicatively connected with the sensor for processing the sensor information and producing a 3-D image of the object. The aperture may have an asymmetrical shape for distinguishing objects in front of versus in back of the focal plane. The aperture may also be rotatable, where the orientation of the observed pattern relative to the oblong aperture is varied with time thereby removing the ambiguity generated by image overlap. The disclosed device further comprises a light projection system configured to project a predetermined pattern onto a surface of the desired object thereby allowing for mapping of unmarked surfaces in three dimensions.

12. A method for three-dimensional (3-D) imaging of an object, comprising acts of:
-
capturing electromagnetic radiation transmitted off of an object and through a lens and a substantially oblong aperture with a sensor, said oblong aperture having an oblong shape; and processing defocused information from the sensor indicative of a distance between edges of the oblong shape to produce a 3-D image representative of the object. - View Dependent Claims (13, 14, 15, 16, 17, 18)
