Highway Visibility Monitoring Method Based on Video Analysis
The article installs a specially designed target with its own light source on site,collects video images containing the target area through a camera,inputs them into an industrial computer for target position recognition,angle correction,and other preprocessing.It extracts the visual feature information of the target area image,and uses the mapping model of the pre-constructed feature information to the visibility distance to calculate the visibility value of the road in real-time,achieving the goal of dynamic monitoring of road visibility all weather.
