  • Publication number: 20180276839
    Abstract: A trailer angle detection system for a vehicle towing a trailer includes a rearward viewing camera disposed at a rear portion of a vehicle, and an image processor operable to process image data captured by the camera. Responsive to processing of captured image data when the vehicle is towing a trailer, the trailer angle detection system determines the presence of the trailer at the rear of the vehicle and attached at the vehicle and determines feature vectors of the detected trailer over multiple frames of captured image data. Responsive to movement of the trailer relative to the vehicle, the trailer angle detection system tracks feature vectors for different positions of the detected trailer. The trailer angle detection system determines an angle of the trailer responsive to detection of tracking of feature vectors the trailer in the field of view of the camera over multiple frames of captured image data.

  • Publication number: 20180276838
    Abstract: A trailer angle detection system for a vehicle towing a trailer includes a camera disposed at a rear portion of a vehicle so as to have a field of view exterior and rearward of the vehicle, and an image processor operable to process image data captured by the camera. Responsive to processing of a region of interest of image data captured by the camera, the trailer angle detection system determines the location of a known patterned target at the trailer being towed by the vehicle. Responsive to determination of the location of the target, the system determines a region of interest of the captured image data that encompasses the target. Responsive to processing of image data of the region of interest and determining the location of the target relative to the vehicle centerline, the trailer angle detection system calculates an angle of the trailer relative to the vehicle centerline.

  • Publication number: 20180278925
    Abstract: A method of calibrating a vehicular camera includes disposing a camera at a vehicle, moving the vehicle along an arbitrary path, capturing image data with the camera, and processing, via a processor, image data captured by the camera. Responsive to tracking a determined feature across multiple frames of captured image data during movement of the vehicle along the arbitrary path, and responsive to received vehicle data representative of the movement of the vehicle along the arbitrary path, misalignment of the camera is determined. The determined camera misalignment is corrected (i) without use of a target in the field of view of the camera as the vehicle moves along the arbitrary path and (ii) without processing of image data captured by the camera that is representative of a target in the field of view of the camera as the vehicle moves along the arbitrary path.

  • Publication number: 20180253608
    Abstract: A trailer angle detection system for a vehicle towing a trailer includes a camera disposed at a rear portion of the vehicle and having a field of view rearward of the vehicle. The camera includes a two dimensional imager array having multiple rows and columns of photosensing elements. An image processor processes image data captured by the camera. With the vehicle towing a trailer, and via processing by the image processor of image data captured by the camera, the trailer angle detection system detects a portion of the trailer that is being towed by the vehicle. The trailer angle detection system determines, via processing by the image processor of image data captured by the camera, an angle of the trailer relative to the vehicle responsive to determination of which columns of photosensing elements sense the detected portion of the trailer in the field of view of the camera.

  • Publication number: 20180215382
    Abstract: A trailer hitching assist system for a vehicle includes a camera disposed at a rear portion of a vehicle and having a field of view rearward of the vehicle. A control includes an image processor operable to process image data captured by the camera. The image processor, via image processing of image data captured by the camera, detects a trailer and trailer hitch rearward of the vehicle and determines a first path of travel for the vehicle to follow so as to maneuver the vehicle so as to have its tow ball aligned with the trailer hitch. The control maneuvers the vehicle along the determined first path of travel. Responsive to detection of an object entering the first path of travel, the control determines a second path of travel and maneuvers the vehicle along the second path of travel to avoid the detected object entering the determined path of travel.

  • Patent number: 9979957
    Abstract: A camera calibration system for a vehicle includes a camera disposed at the vehicle and an image processor operable to process image data captured by the camera. The camera calibration system generates camera calibration parameters at least in part by iteratively refining calibration parameters starting from at least one of (i) an initial estimation and (ii) an intrinsic parameter of the camera. The camera calibration system uses a kinematic model of vehicle motion derived at least in part from image processing of multiple frames of captured image data. Responsive to such image processing, the camera calibration system extracts and matches features determined in multiple frames of captured image data. Responsive to image processing during movement of the vehicle along an arbitrary path, and responsive to generation of camera calibration parameters, the camera calibration system calibrates the camera as the vehicle navigates the arbitrary path.

  • Publication number: 20160180182
    Abstract: A vision system of a vehicle includes at least one camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. Responsive to image processing of captured image data and with the at least one camera disposed at the vehicle, the image processor determines a three dimensional object present in the field of view of the camera and determines a point of interest on the determined object. The vision system uses triangulation to determine an estimated location in three dimensional space of the determined point of interest. The vision system processes additional frames of captured image data to enhance the estimation of the location in three dimensional space of the determined point of interest. The image processor is operable to estimate a distance to the determined object by comparing multiple frames of captured image data.
