First Claim
Patent Images
1. A method for detecting a lane marker in a roadway, the method comprising:
- receiving, from an image acquisition device, a first image comprising the lane marker;
scanning, into a memory, a first substantially horizontal line across the first image;
computing, using a processor, an intensity gradient of the first substantially horizontal line; and
determining a first position of the lane marker by analyzing the intensity gradient.

Abstract
A method for detecting a lane marker, the method including (i) receiving, from an image acquisition device, a first image comprising the road lane marker, (ii) scanning, into a memory, a first substantially horizontal line across the first image, (iii) computing, using a processor, an intensity gradient from the first scanned line, and (iv) determining a first position of the road lane marker by analyzing the intensity gradient.
