Crosswalk detection

The automated identification and localization of marked pedestrian crossings in imagery using computer vision techniques. Crosswalk detection can be performed on satellite images, street-level photographs, or real-time camera feeds to populate navigation databases for blind pedestrians, support urban infrastructure auditing, or provide real-time guidance during street crossings. The technology is important for accessibility because crosswalk locations are not systematically catalogued in most mapping databases despite being critical for safe pedestrian navigation by people with visual impairments.
