Abstract: A method and system are disclosed for identifying a trailer or trailer coupler in an image. The method includes obtaining a database of descriptor clusters. Each descriptor cluster has at least one label assigned thereto. Each at least one label is a label for a trailer or trailer coupler, or for a background. Image data pertaining to an image is received. Features and descriptors are determined in the received image data. For each determined descriptor, the method includes matching the determined descriptor with a descriptor cluster in the database and assigning the label corresponding to the matched descriptor cluster to the determined descriptor. Based upon the determined descriptors having the assigned label corresponding to one of a trailer or a trailer coupler, the method includes determining a convex hull of a representation of the one of the trailer or trailer coupler in the image.

Abstract: A method for determining a trailer angle between a tow vehicle and a trailer attached to the tow vehicle includes receiving images from a camera positioned on a rear portion of the tow vehicle with a data processing hardware device, determining visual features from the images, tracking the visual features while the tow vehicle and trailer are moving and calculating, at the data processing hardware, the trailer angle based on the visual features. The trailer angle is then transmitted from the data processing hardware to one or more vehicle systems.

Abstract: A method for visual trailer tracking of vehicle-trailer angle estimation, including: (a) camera receiving images, each most recently received image being identified as a current image, replacing a previously identified current image; (b) during a driving maneuver, extracting visual features from the current image, calculating a trailer angle from the current image, and storing the current image as a reference image, the trailer angle as a trailer angle reference and the extracted visual features as visual reference features; and (c) matching the visual features from the current image with the visual reference features. When a number of matches is below a threshold, repeating operation (c) to update the reference image, the trailer angle reference and the visual reference features. The method includes calculating a trailer angle between a trailer representation in the current image and a trailer representation in the reference image based in part upon the trailer angle reference.

Abstract: A method and system for a vehicle control system generates maps utilized for charting a path of a vehicle through an environment. The method performed by the system obtains information indicative of vehicle movement from at least one vehicle system and images including objects within an environment from a camera mounted on the vehicle. The system uses the gathered information and images to create a depth map of the environment.
