摘要： A method and device for high-resolution three-dimensional (3-D) imaging which obtains camera pose using defocusing is disclosed. The device comprises a lens obstructed by a mask having two sets of apertures. The first set of apertures produces a plurality of defocused images of the object, which are used to obtain camera pose. The second set of optical filters produces a plurality of defocused images of a projected pattern of markers on the object. The images produced by the second set of apertures are differentiable from the images used to determine pose, and are used to construct a detailed 3-D image of the object. Using the known change in camera pose between captured images, the 3-D images produced can be overlaid to produce a high-resolution 3-D image of the object.

摘要： A device and method for three-dimensional (3-D) imaging using a defocusing technique is disclosed. The device comprises a lens, a central aperture located along an optical axis for projecting an entire image of a target object, at least one defocusing aperture located off of the optical axis, a sensor operable for capturing electromagnetic radiation transmitted from an object through the lens and the central aperture and the at least one defocusing aperture, and a processor communicatively connected with the sensor for processing the sensor information and producing a 3-D image of the object. Different optical filters can be used for the central aperture and the defocusing apertures respectively, whereby a background image produced by the central aperture can be easily distinguished from defocused images produced by the defocusing apertures.

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.
