VEHICULAR IMAGING SYSTEM AND METHOD FOR DETERMINING ROADWAY WIDTH
First Claim
Patent Images
1. A vehicular imaging system for determining roadway width comprising:
- an image sensor configured for capturing images;
an image processor configured for receiving captured images; and
wherein the image sensor configured to view substantially forward of a vehicle, such that a field of view of the image sensor includes the roadway and roadway marker signs on both the right side and left side of the roadway;
wherein the image processor is configured to determine roadway width by identifying roadway marker signs in processed images that are captured by the image sensor.

Abstract
A vehicular imaging system for determining roadway width includes an image sensor for capturing images and an image processor for receiving the captured images. The image processor determines roadway width by identifying roadway marker signs and oncoming traffic in processed images captured by the image sensor and determining the number of lanes, vehicle location on the roadway based on the roadway size and/or width and location of oncoming traffic.
