20080204900 | THREE-CHANNEL CAMERA SYSTEMS WITH NON-COLLINEAR APERTURES - A three-dimensional imaging system uses a single primary optical lens along with three non-collinear apertures to obtain three offset optical channels each of which can be separately captured with an optical sensor. | 08-28-2008 |
20090016642 | METHOD AND SYSTEM FOR HIGH RESOLUTION, ULTRA FAST 3-D IMAGING - A high-speed three-dimensional imaging system includes a single lens camera subsystem with an active imaging element and CCD element, and a correlation processing subsystem. The active imaging element can be a rotating aperture which allows adjustable non-equilateral spacing between defocused images to achieve greater depth of field and higher sub-pixel displacement accuracy. A speckle pattern is projected onto an object and images of the resulting pattern are acquired from multiple angles. The images are locally cross-correlated using a sparse array image correlation technique and the surface is resolved by using relative camera position information to calculate the three-dimensional coordinates of each locally correlated region. Increased resolution and accuracy are provided by recursively correlating the images down to the level of individual points of light and using the Gaussian nature of the projected speckle pattern to determine subpixel displacement between images. Processing is done at very high-speeds by compressing the images before they are correlated. Correlation errors are eliminated during processing by a technique based on the multiplication of correlation table elements from one or more adjacent regions. | 01-15-2009 |

20110128412 | Actively Addressable Aperture Light Field Camera - An actively addressable aperture disposed ahead of the rear surface of a camera lens allows the camera to capture a full-resolution, five-dimensional (5D) light field that describes every possible view from every possible angle of the scene being imaged. Shifting the aperture over the entire aperture plane and acquiring an image at each step yields a 2D grid of 2D images of the scene, otherwise known as a 4D parameterized light field. Estimating the 3D depth of the objects in the imaged scene yields a 3D model with 2D surface irradiance patterns, which is the full, non-parameterized 5D light field. The 5D light field can be used to display perspective changes in a way that mimics cognitive processing of the same scene or object. 5D light fields can also be used to create high-precision, 3D depth maps suitable for 3D movies, interactive displays, machine vision, and other applications. | 06-02-2011 |
