Abstract: A vehicle hatch clearance determining system includes a plurality of cameras disposed at the vehicle and a control having a processor for processing image data captured by the cameras to determine structure and objects present in the fields of view of the cameras while the vehicle is being driven during a parking event. The control, responsive to processing of captured image data, determines and stores information pertaining to structure and objects present in the fields of view of the cameras during the parking event. When the vehicle is parked, the control determines if stored information includes structure or an object at or near the parking location and in a region that may be swept by the vehicle hatch when it is opened or closed. Responsive to determination of a potential collision of the hatch with structure or an object, the clearance determining system controls the hatch and/or generates an alert.

Abstract: A calibration system for calibrating a radar sensing system for a vehicle includes at least one calibrating radar transmitter spaced from a location where the vehicle may be positioned. The vehicle includes a radar sensor disposed at the vehicle so as to sense exterior of the vehicle. The radar sensor includes a plurality of transmitters that transmit radio signals and a plurality of receivers that receive radio signals that are transmitted radio signals reflected from an object. A processor is operable to process an output of the receivers. With the vehicle positioned at the location, the at least one calibrating transmitter transmits signals that are received by the receivers of the radar sensor. Responsive to processing by the processor of the output of the receivers when receiving signals transmitted by the at least one calibrating transmitter, the calibration system determines if the radar sensor is misaligned at the vehicle.

Abstract: A vehicle hatch clearance determining system includes a plurality of cameras disposed at the vehicle and a control having a processor for processing image data captured by the cameras. During a parking event, and responsive to processing of captured image data, the system detects objects, gathers information pertaining to detected objects exterior the vehicle and generates an environmental model based at least in part on the gathered information. With the vehicle parked, the system determines location of the vehicle relative to at least one detected object of the environmental model and determines if the model includes an object in a region that would be swept by a hatch of the parked vehicle when the hatch is being opened or closed. Responsive to determination that the object is in the region that would be swept by the hatch, the system stops movement of the hatch to avoid impact with the object.

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 calibration system for calibrating a LIDAR sensing system of a vehicle includes a plurality of light reflecting targets disposed at a ground surface at an end of line calibration region of a vehicle assembly facility. The light reflecting targets are arranged at the ground surface in a predetermined pattern. When a vehicle equipped with a LIDAR sensing system is at the calibration region, the light reflecting targets are in the field of sensing of at least one LIDAR sensor of the LIDAR sensing system of the vehicle. Responsive to processing of data sensed by the at least one LIDAR sensor, the calibration system determines the locations of the light reflecting targets and determines misalignment of the LIDAR sensor and calibrates the LIDAR sensing system to accommodate the determined misalignment.

Abstract: A method for calibrating a camera of a vehicular vision system includes providing a camera and an image processor at the vehicle. A monoview noncoplanar three dimensional calibration pattern distributed on a semi-sphere is determined via processing of image data captured by the camera. Responsive to determination of the monoview noncoplanar three dimensional calibration pattern distributed on the semi-sphere, extrinsic parameters of the camera and intrinsic parameters of the camera are estimated. The system performs at least one of (i) a linear refinement of the estimated extrinsic parameters and intrinsic parameters and (ii) a non-linear refinement of the estimated extrinsic parameters and intrinsic parameters. Responsive to processing by the image processor of image data captured by the camera, the camera is calibrated at least in part by using the determined monoview noncoplanar three dimensional semi-spherical calibration pattern.

Abstract: A camera calibration system for cameras of a vehicle includes a plurality of cameras disposed at a vehicle and having respective fields of view exterior of the vehicle. The fields of view of at least two of the cameras overlap. An image processor is operable to process image data captured by the cameras to determine features in the overlapping regions of the fields of view of the at least two cameras. The camera calibration system determines a best fitting camera model based on actual geometric properties of each of the cameras. A display screen is disposed in the vehicle for displaying images derived from image data captured by the at least two cameras for viewing by a driver of the vehicle. Responsive to determining a best fitting camera model, the display screen displays images derived from image data captured by the at least two cameras.

Abstract: A camera for a vision system for a vehicle includes a front housing portion, a lens assembly disposed at the front housing portion and an imager disposed at a circuit element. A planar rigid spacer having uniform thickness is disposed between the lens assembly and the imager. At least a circumferential portion of a front surface of the planar rigid spacer is secured at a portion of the front housing portion and at least a circumferential portion of a rear surface of the planar rigid spacer is secured at one of the imager and the circuit element. The planar rigid spacer accurately spaces the imager from the lens assembly and the predetermined thickness of the planar rigid spacer is selected so that the lens assembly focuses incident light onto the imager.
