Abstract: A vision system of a vehicle includes a camera disposed at a vehicle and having a field of view that encompasses first and second regions exterior of the vehicle. The camera captures image data that includes a first set of image data representative of the first region of the field of view and a second set of image data representative of the second region of the field of view. An image processor processes the first set of image data to detect a pedestrian present in the first region based on a first predetermined orientation of a pedestrian. The image processor processes the second set of image data to detect a pedestrian present in the second region based on a second predetermined orientation of a pedestrian.

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.

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.

Abstract: A vision system for a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. A processor is operable to process image data captured by the camera. The vision system determines conditions where processing of captured image data degrades in performance due to environmental conditions. The vision system, responsive to a determined condition, determines a safe state for image processing of captured image data for that determined condition. A failsafe algorithm, responsive to processing of image data captured by the camera and responsive to the determined condition, and in accordance with the determined safe state for that determined condition, determines true negatives and avoids false positives and false negatives.

Abstract: A vision system of a vehicle includes at least one camera disposed at a vehicle and having a field of view exterior of the vehicle, and an image processor operable to process image data captured by the camera. Responsive to image processing of captured image data, the image processor determines objects present in the field of view of the camera. The vision system processes additional frames of captured image data to enhance determination of objects of interest. The vision system initially detects objects present in the field of view of the camera and conducts hypotheses filtering and hypotheses merging and, responsive to the hypotheses filtering and hypotheses merging, the system predicts hypotheses and evaluates the predicted hypotheses to determine objects of interest from objects not of interest.

Abstract: A vision system of a vehicle includes a camera disposed at the vehicle and having a field of view exterior of the vehicle. A control has an image processor that is operable, via image processing of frames of image data captured by the camera, to detect an object present in the field of view of the camera. When the vehicle is moving, the control, responsive at least in part to vehicle motion information and image processing of frames of captured image data, determines motion of the detected object relative to the moving vehicle. The control determines the relative motion of the detected object by (i) determining corresponding object points in at least two frames of captured image data, (ii) estimating object motion trajectory of the detected object responsive to the determination of corresponding object points and (iii) determining the structure of the detected object along the estimated object motion trajectory.

Abstract: A vehicle vision system includes a plurality of cameras disposed at a vehicle and having respective fields of view exterior of the vehicle. An image processor is operable, responsive to image processing of captured image data, to synthesize captured image data to generate a reduced distortion bird's-eye view image of a region exterior and near the vehicle and encompassed by the fields of view of the cameras. A display displays the bird's-eye view image for viewing by a driver of the vehicle. The image processor processes synthesized captured image data using a lane marker sensing algorithm that utilizes recursive temporal stabilization to determine lane markings in the field of view of at least the rear camera. The system determines when the vehicle is departing from its being-traveled lane and, responsive to determination that the vehicle is departing from its being-traveled lane, generates an alert to the driver of the vehicle.

Abstract: A vehicular trailer angle detection system includes a camera disposed at a rear portion of a vehicle. The vehicular trailer angle detection system, via processing of frames of image data captured by the camera, tracks changes of features present in a current frame of captured image data and present in a previous frame of captured image data and determines features of the trailer based on the tracked changes of features. The determined features of the trailer have respective changes between the current frame of image data captured by the camera and the previous frame of image data captured by the camera. The vehicular trailer angle detection system determines angle of the trailer relative to the vehicle based at least in part on tracking of the determined features of the trailer over multiple captured frames of image data.

Abstract: A vehicular parking assist system includes a plurality of sensors disposed at a vehicle and sensing exterior of the vehicle. The vehicular parking assist system, via processing of captured sensor data, and while the vehicle is conducting a parking maneuver, detects an object and tracks location of the detected object relative to the vehicle until the detected object leaves a field of sensing of the at least one sensor of the plurality of sensors. The system, after the detected object leaves the field of sensing of the at least one sensor, predicts location of the detected object relative to the vehicle. The system, upon completion of the parking maneuver, determines that the detected object is hazardous based on the predicted location of the detected object relative to the vehicle, and responsive to determining that the detected object is hazardous, restricts opening of a door of the vehicle.
