Publication number: 20130101160Abstract: A system for generating disparity results comprises an interface, a first memory, a second memory, and a processor. The interface is for receiving a first element of a first set of image data and a first element of a second set of image data. The first memory is for storing the first element of the first set of image data. The second memory is for storing the first element of the second set of image data. The processor is for generating a disparity result for a first element before all elements of the first data set and the second data set have been received. The disparity result is generated using a low latency image processing system that processes a plurality of elements of the first set of image data and a plurality of elements of the second set of image data.Type: ApplicationFiled: August 1, 2012Publication date: April 25, 2013Applicant: TYZX, INC.Inventors: John Iselin Woodfill, Henry Harlyn Baker, Brian Von Herzen, Robert Dale Alkire

Publication number: 20120287287Abstract: A system for determining one or more camera calibration parameters is disclosed. The system comprises a processor and a memory. The processor is configured to: a) provide a first pattern for display on a display screen; b) receive a first image from a camera viewing the display screen; c) provide a second pattern for display on the display screen; and d) receive a second image from the camera viewing the display screen. The relative position of the display screen and the camera are the same as when the first image was captured using the camera. The processor is further configured to determine an image location which is a projection of a known physical location on the display screen by using at least in part a first feature identified in the first image and a second feature identified in the second image and determine one or more calibration parameters based at least in part on the determined image location. The memory is coupled to the processor and configured to provide the processor with instructions.Type: ApplicationFiled: May 11, 2011Publication date: November 15, 2012Applicant: TYZX, INC.Inventors: Etienne Grossmann, John Iselin Woodfill, Gaile Gibson Gordon

Publication number: 20120287240Abstract: A system for computing one or more calibration parameters of a camera is disclosed. The system comprises a processor and a memory. The processor is configured to provide a first object either marked with or displaying three or more fiducial points. The fiducial points have known 3D positions in a first object reference frame. The processor is further configured to provide a second object either marked with or displaying three or more fiducial points. The fiducial points had known 3D positions in a second object reference frame. The processor is further configured to place the first object and the second object in a fixed position such that the fiducial point positions of the first and second objects are non-planar. The processor is further configured to compute one or more calibration parameters of the second camera using computations based on images taken of the fiducials.Type: ApplicationFiled: May 11, 2011Publication date: November 15, 2012Applicant: TYZX, INC.Inventors: Etienne Grossmann, John Iselin Woodfill, Gaile Gibson Gordon

Patent number: 8260040Abstract: A powerful, scaleable, and reconfigurable image processing system and method of processing data therein is described. This general purpose, reconfigurable engine with toroidal topology, distributed memory, and wide bandwidth I/O are capable of solving real applications at real-time speeds. The reconfigurable image processing system can be optimized to efficiently perform specialized computations, such as real-time video and audio processing. This reconfigurable image processing system provides high performance via high computational density, high memory bandwidth, and high I/O bandwidth. Generally, the reconfigurable image processing system and its control structure include a homogeneous array of 16 field programmable gate arrays (FPGA) and 16 static random access memories (SRAM) arranged in a partial torus configuration. The reconfigurable image processing system also includes a PCI bus interface chip, a clock control chip, and a datapath chip. It can be implemented in a single board.Type: GrantFiled: March 2, 2011Date of Patent: September 4, 2012Assignee: Tyzx, Inc.Inventors: John Iselin Woodfill, Henry Harlyn Baker, Brian Von Herzen, Robert Dale Alkire

Patent number: 8238611Abstract: A system for distance calculation is disclosed. The system includes an illuminator unit, one or more camera units, and a distance processor. The illuminator unit illuminates a scene in a target area using a textured pattern creator and wherein the textured pattern creator includes a diffractive optical element. The one or more camera units captures two or more images of the target area from two or more physical locations. A textured pattern illumination is visible in each of the two or more images of the target area. The images are used to calculate distances to one or more points in the scene in the target area.Type: GrantFiled: May 20, 2011Date of Patent: August 7, 2012Assignee: Tyzx, Inc.Inventors: Pierre St. Hilaire, Gaile Gibson Gordon, John Iselin Woodfill, Ronald John Buck, Steve Clohset
