Patent number: 7613323Abstract: A method and apparatus for determining camera pose characterized by six degrees of freedom (e.g., for use in computer vision systems) is disclosed. In one embodiment an image captured by the camera is received, and at least two constraints on the potential pose are enforced in accordance with known relations of the image to the camera, such that the potential pose is constrained to two remaining degrees of freedom. At least one potential pose is then determined in accordance with the remaining two degrees of freedom.Type: GrantFiled: June 22, 2005Date of Patent: November 3, 2009Assignee: Sarnoff CorporationInventors: David Nister, James Bergen

Publication number: 20080089556Abstract: A method for detecting a moving target is disclosed that receives a plurality of images from at least one camera; receives a measurement of scale from one of a measurement device and a second camera; calculates the pose of the at least one camera over time based on the plurality of images and the measurement of scale; selects a reference image and an inspection image from the plurality of images of the at least one camera; and detects a moving target from the reference image and the inspection image based on the orientation of corresponding portions in the reference image and the inspection image relative to a location of an epipolar direction common to the reference image and the inspection image; and displays any detected moving target on a display. The measurement of scale can derived from a second camera or, for example, a wheel odometer.Type: ApplicationFiled: June 15, 2007Publication date: April 17, 2008Inventors: Garbis Salgian, Supun Samarasekera, Jiangjian Xiao, James Bergen, Rakesh Kumar, Feng Han

Publication number: 20070288141Abstract: A method and apparatus for visual odometry (e.g., for navigating a surrounding environment) is disclosed. In one embodiment a sequence of scene imagery is received (e.g., from a video camera or a stereo head) that represents at least a portion of the surrounding environment. The sequence of scene imagery is processed (e.g., in accordance with video processing techniques) to derive an estimate of a pose relative to the surrounding environment. This estimate may be further supplemented with data from other sensors, such as a global positioning system or inertial or mechanical sensors.Type: ApplicationFiled: June 22, 2005Publication date: December 13, 2007Inventors: James Bergen, Oleg Naroditsky, David Nister

Publication number: 20050265633Abstract: A video processor that uses a low latency pyramid processing technique for fusing images from multiple sensors. The imagery from multiple sensors is enhanced, warped into alignment, and then fused with one another in a manner that provides the fusing to occur within a single frame of video, i.e., sub-frame processing. Such sub-frame processing results in a sub-frame delay between a moment of capturing the images to the display of the fused imagery.Type: ApplicationFiled: May 25, 2005Publication date: December 1, 2005Inventors: Michael Piacentino, Gooitzen Siemen van der Wal, Peter Burt, James Bergen

Publication number: 20050175085Abstract: A method and apparatus for encoding a data sequence is disclosed. A data sequence is received. The data sequence is encoded such that the encoded data sequence comprises a plurality of data elements having assigned priorities. Data packets are generated using the encoded data sequence, where each data packet comprises only data elements of identical priority. The data packets are tagged with a priority descriptor indicating the priority of the data elements contained therein. Also disclosed is a method and apparatus for processing at least one packet. At least one packet is received, where each packet includes a priority descriptor that indicates a priority of at least one data element contained therein. Packets may then be selectively discarded based upon the priority descriptor.Type: ApplicationFiled: January 24, 2005Publication date: August 11, 2005Inventors: James Bergen, Michael Isnardi, Christos Polyzois
