Illegal emergency lane occupancy detection method

Abstract

The invention provides an illegal emergency lane occupancy detection method. The method comprises the following steps: acquiring a road image; detecting lane line edge lines; removing typical non-emergency lane line edge lines; removing interference lane line edge lines; determining types of the lane line edge lines; determining candidate emergency lane line edge line positions; determining the current frame of emergency lane line edge line position; determining an emergency lane area; detecting vehicles occupying the emergency lane; carrying out vehicle license plate recognition on the detected vehicles; and storing snapshot data. According to the method provided by the invention, a video image analysis technology is adopted to accurately position the emergency lane areas in real time and automatically snapshooting the vehicles in the emergency lane areas; and the method has the characteristics of realizing all-section snapshooting and being real-time, efficient and accurate in snapshooting.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic monitoring, in particular to a detection method for illegally occupying emergency lanes. Background technique [0002] The expressway emergency lane is a rescue channel specially set up for the public, and it is a life channel for emergency rescue at a critical moment. In accordance with the relevant provisions of the "Road Traffic Safety Law of the People's Republic of China" and the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": Except for police cars, fire trucks, engineering emergency vehicles, and ambulances performing emergency tasks, other motor vehicles are not allowed to enter Drive or stop in the emergency lane. However, with the rapid growth of the number of cars in our country, more and more drivers like to illegally occupy the emergency lane to drive or wait when the expressway is congested, and some drivers even ove...

Problems solved by technology

However, with the rapid growth of the number of cars in our country, more and more drivers like to illegally occupy the emergency lane to drive or wait when the expressway is congested, and some drivers even overtake in the emergency lane at will when the traffic is smooth. Or temporary parking, which is a very dangerous behavior. Once a traffic accident occurs ahead, it will often cause police cars and rescue vehicles to be unable to reach the scene quickly, prolonging the time of traffic congestion, causing difficulties in rescue, and aggravating the consequences of accident damage.

[0003] In recent years, in order to control the illegal occupation of emergency lanes, the traffic police department has carried out corresponding rectification actions, using the highway monitoring system and the camcorders and cameras equipped by the police to capture and collect evidence of illegal occupation of emergency lanes. However, this method However, it has great limitations. First, the expressway monitoring system cannot monitor the entire road section. Secondly, the police manually capture the pictures through the camcorder and camera. Although they can capture the entire road section, the efficiency is low. High-efficiency new capture technology
