    Abstract: A camera calibration method for calibrating at least one camera of a vehicle includes providing a target area for a vehicle to be positioned at, with the vehicle having a forward camera, a rearward camera and opposite side cameras. When the vehicle is positioned at the target area, a target is electronically generated at an area that is encompassed by the field of view of one of the cameras or at an overlapping portion of the fields of view of two of the cameras of the vehicle. Image data is captured by the two cameras that is representative of the generated target. Image data captured by the two cameras is processed to detect the target in the fields of view of the two cameras. At least one of the two cameras is calibrated responsive to detection of the target.

    Abstract: A method for calibrating a vehicular radar sensing system includes disposing two spaced apart calibrating radars at respective transmitting locations that are spaced from a vehicle calibration location at an end of line portion of a vehicle assembly line, and moving a vehicle along the vehicle assembly line, the vehicle including an electronic control unit (ECU) and a vehicular radar operable to sense exterior of the vehicle. Signals are transmitted via the first and second calibrating radars at the transmitting locations and, with the vehicle at the vehicle calibration location, the plurality of radar receivers of the vehicular radar receive the transmitted signals transmitted by the first and second calibrating radars, and the vehicular radar generates an output that is processed at the ECU. Responsive to processing at the ECU of the output of the vehicular radar, misalignment of the vehicular radar at the vehicle is determined.

    Abstract: A method of calibrating a vehicular camera includes mounting a camera at a vehicle moving along a vehicle assembly line. Responsive to processing of image data captured by the camera, features at the ground adjacent to the vehicle are determined and the determined features are tracked over two or more frames of captured image data. Responsive to processing of frames of captured image data during movement of the vehicle along a straight path, a misalignment of the camera is determined. The misaligned camera is calibrated using an assumption that the determined ground features lie in a plane parallel to a planar portion of the ground surface adjacent the straight path portion of the vehicle assembly line. The determination of misalignment and the calibration of the camera are performed without use of a target pattern at the vehicle assembly line.

    Abstract: A vehicular trailer backup assist system is operable to steer a vehicle, with a trailer connected at the rear of the vehicle, during a reversing maneuver of the vehicle and trailer. The system electronically overlays a plurality of zones over displayed video images, with each individual zone of the overlayed plurality of zones being indicative of a respective individual region rearward of the vehicle and trailer. Responsive to a selected zone of travel for the trailer, the control controls steering of the vehicle to steer the vehicle to guide the trailer towards the respective individual region that is encompassed by the selected zone of travel during reversing of the vehicle and trailer. The driver of the vehicle manually adjusts steering of the vehicle to more accurately steer the vehicle towards a target location within the respective individual region that is encompassed by the selected zone of travel.

    Abstract: A camera calibration system for calibrating cameras of a vehicle includes at least one reconfigurable calibration target established or disposed at a ground area at which a vehicle is positioned for a camera calibrating procedure. The camera calibration system is operable, responsive to an input indicative of a type or size of the vehicle positioned at the ground area, to reconfigure the at least one reconfigurable calibration target to adapt the calibration target for the particular type or size of the vehicle positioned thereat. The camera calibration system may reconfigure at least one of a size of the target and a location of the target. The camera calibration system may reconfigure the target via a covering element that selectively exposes a portion of the reconfigurable calibration target and covers another portion of the reconfigurable calibration target.

    Abstract: A method includes disposing a spherical radar reflector at a location exterior a vehicle equipped with the vehicular sensing system. The vehicular sensing system includes at least two radar sensors disposed at the vehicle and a controller that processes received radio frequency (RF) signals received by the plurality of receivers of each radar sensor of the at least two radar sensors. Calibration RF signals are transmitted by at least one transmitting antenna of a plurality of transmitters of a first radar sensor and a second radar sensor the at least two radar sensors, and reflected first calibration RF signals are received by the plurality of receivers of the first radar sensor and the second radar sensor. Based on a distance between the first radar sensor, the second radar sensor, and the spherical reflector, the vehicular sensing system determines an orientation of the first radar sensor and the second radar sensor.

    Abstract: A method of calibrating a vehicular vision system includes mounting a camera at a vehicle moving along a vehicle assembly line. Responsive to processing of image data captured by the camera, ground features adjacent to the vehicle are determined and the determined ground features are tracked over two or more frames of captured image data using optical flow. A misalignment of the camera is determined via tracking the determined ground features as the vehicle moves along the straight path portion of the end of line test portion of the vehicle assembly line. Responsive to determination of misalignment of the camera at the vehicle, the vehicular vision system is calibrated using an assumption that the determined ground features lie in a plane parallel to a planar portion of a ground surface adjacent the straight path portion of the end of line test portion of the vehicle assembly line.
