Patent Images

1. A method for identifying roadway objects for a vehicle, the method comprising:

  • determining, using a camera sensor communicatively coupled to an onboard computer of a vehicle, a real-time image of a road;

    dividing the real-time image into superpixels;

    merging the superpixels to form superpixel regions based on similarity of the superpixels;

    generating prior maps from a dataset of road scene images, the prior maps including a road prior map;

    drawing a set of bounding boxes where each bounding box surrounds one of the superpixel regions;

    comparing bounding boxes in the set of bounding boxes to the road prior map to identify a road region in the real-time image;

    pruning bounding boxes from the set of bounding boxes that are outside the road region to reduce the set to remaining bounding boxes; and

    performing feature extraction and categorization to identify objects within the set of remaining bounding boxes.
