摘要: 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 may be modified in order to successfully generate surface maps of objects or three-dimensional representations of target objects. A variety of the aspects of the present invention provide examples of the use of an addressable pattern in order to overcome mismatching common to standard defocusing techniques.

摘要: 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.
