Abstract
A lane departure warning system includes a memory and a processor for validating a candidate region as including an image of a lane marker on the road is disclosed. The candidate region is identified within a latest road image of a temporal sequence of road images captured from the front of a vehicle traveling along a road. The memory stores non-transitory computer-readable instructions and adapted to store the road image. The image processor is adapted to execute the instructions to, when no previously-verified region and no previously-rejected region aligns with the candidate region: (i) determine a minimum distance between the candidate region and a previously-verified region of a previously-captured road image of the sequence, (ii) when the minimum distance exceeds a threshold distance, store the candidate region as a verified region, and (iii) when the minimum distance is less than the threshold distance, store the candidate region as a rejected region.
