Three-dimensional imaging system for robot vision
First Claim
1. A three-dimensional imaging system for robot vision comprising:
- (a) a lens system, comprising a variable focal length micromirror array lens (MMAL), configured to change the focal plane by changing the focal length of the variable focal length MMAL;
(b) an imaging unit, optically coupled to the lens system, configured to receive an object image from the lens system and to sense the object image; and
(c) an image processing unit, communicatively coupled to the imaging unit, configured to process the object images sensed by the imaging unit and to generate an all-in-focus image and three-dimensional position information of the object.

Abstract
The present invention provides a three-dimensional imaging system for robot vision, which is capable of three-dimensional positioning of objects, object identification, searching and tracking of an object of interest, and compensating the aberration of the system. The three-dimensional imaging system for robot vision comprises one or more camera systems, each of which has at least one variable focal length micromirror array lens, an imaging unit, and an image processing unit. The variable focal length micromirror array lens used in the three-dimensional imaging system for robot vision has unique features including a variable focal length, a variable focal axis, and a variable field of view with a fast response time.
