Patent number: 11820423Abstract: A vehicular trailering assist system includes at least one camera disposed at a trailer hitched to a hitch of a vehicle, and an electronic control unit (ECU). The ECU determines, during a first stage of a calibration maneuver of the vehicle and trailer, image coordinates of at least one ground feature point. The ECU, responsive to determining image coordinates of the at least one ground feature point, estimates orientation parameters of the camera based at least on the determined image coordinates and intrinsic camera parameters. As the vehicle and trailer travel further along the ground surface during a second stage of the calibration maneuver of the vehicle and trailer, and based on the estimated orientation parameters of the at least one camera, the vehicular trailering assist system determines misalignment of the at least one camera at the trailer.Type: GrantFiled: March 20, 2023Date of Patent: November 21, 2023Assignee: Magna Electronics Inc.Inventors: Galina Okouneva, James Turk, Anam M.

Patent number: 11447070Abstract: A method for determining misalignment of a vehicular camera includes equipping a vehicle with a vehicular vision system having an electronic control unit and a plurality of cameras disposed at the vehicle so that each camera has a respective field of view exterior of the vehicle. Responsive to processing at the electronic control unit of received vehicle data during driving of the vehicle, the vehicular vision system determines a vehicle motion vector during driving of the vehicle. Frames of image data captured by the plurality of cameras are processed to determine an object motion vector of a detected object based on positions of the detected object in frames of image data captured by the camera. The determined object motion vector is compared to the determined vehicle motion vector to determine via the vehicular vision system that the camera of the plurality of cameras is misaligned.Type: GrantFiled: September 21, 2020Date of Patent: September 20, 2022Assignee: MAGNA ELECTRONICS INC.Inventor: James Turk

Patent number: 11410334Abstract: A method for calibrating a vehicular camera of a vehicular vision system includes placing a target with a first portion having a first geometric pattern and a second portion having a second geometric pattern within the field of view of the vehicular camera, and capturing image data with the camera representative of the field of view of the vehicular camera. Two edges of both portions of the target are detected, and edge pixels of the detected edges are determined. First and second vanishing points of the target in the captured image data are determined based on the determined edge pixels of the respective first and second portions of the target. Camera orientation is determined based on location of the determined first vanishing point relative to location of the determined second vanishing point. The vehicular camera is calibrated based on the determined camera orientation.Type: GrantFiled: February 3, 2021Date of Patent: August 9, 2022Assignee: MAGNA ELECTRONICS INC.Inventors: Tao-I Hsu, James Turk, Alexander Velichko

Publication number: 20070244812Abstract: A system and method to allow gold to circulate as digital cash through the global computer network (Internet) and/or private communication networks much like cash currently circulates in the physical world. A computer system (emint) will create digital representations of gold (ecoins). Each ecoin will represent a weight of gold held at a participating secure storage facility (storage site), and each ecoin is given by the emint a unique identifier by which it can be distinguished and identified. The sum total of all circulating ecoins (denominated in physical measures such as weights such as grams and/or ounces and fractions thereof) will equal the weight of all the gold held for safekeeping at the storage site(s) for the users of the emint. The ownership of gold is not transferred by a computer system executing debits and credits between individual accounts, but instead by individuals directly transferring ecoins amongst themselves (as is done in cash transactions, i.e., without double-entry bookkeeping).Type: ApplicationFiled: April 16, 2007Publication date: October 18, 2007Inventors: James Turk, Geoffrey Turk
