METHOD AND SYSTEM FOR UNIVERSAL LANE BOUNDARY DETECTION
First Claim
Patent Images
1. A method of detecting road or lane identifiers, comprising the steps of:
- receiving an image of a road in front of a vehicle from an imager;
determining a region of interest in an identified road in the image; and
detecting road markings by detecting lane markings in the region of interest, and if lane markings cannot be detected, then detecting road boundaries in the region of interest.

Abstract
A method and system for detecting road markings, is provided. One implementation involves receiving an image (3) of a road (4) in front of a vehicle (2) from an imager (1), determining a region of interest in an identified road in the image, and detecting road markings (8L1 8R) by detecting lane markings (7L, 7R) in the region of interest, and if lane markings cannot be detected, then detecting road boundaries in the region of interest.
