  • Method and system for robust curb and bump detection from front or rear monocular cameras
    Patent number: 10108866
    Abstract: A method of detecting a curb. An image of a path of travel is captured by a monocular image capture device mounted to a vehicle. A feature extraction technique is applied by a processor to the captured image. A classifier is applied to the extracted features to identify a candidate region in the image. Curb edges are localized by the processor in the candidate region of the image by extracting edge points. Candidate curbs are identified as a function of the extracted edge points. A pair of parallel curves is selected representing the candidate curb. A range from image capture device to the candidate curb is determined. A height of the candidate curb is determined. A vehicle application is enabled to assist a driver in maneuvering a vehicle utilizing the determined range and depth of the candidate curb.
