A UAV-based detection method for illegal occupancy of emergency lanes

Abstract

The present invention provides a method for detecting illegal occupation of emergency lanes based on drones, including: releasing drones; locating the right edge of the road; judging whether to locate the right edge of the road; adjusting the orientation of the drone; selecting the emergency lane area; Detect vehicle position; judge whether the vehicle position is successfully detected; license plate character recognition; store vehicle information; correct the flight angle of the drone; the drone automatically moves forward; determine whether the drone has flown to the specified distance; retract the drone. The invention realizes the automatic flight control of the UAV, can ignore any traffic obstacles, accurately locates the emergency lane area in real time through video image analysis technology, and automatically captures the vehicles appearing in the emergency lane area. Features such as real-time efficiency, accurate capture, and barrier-free.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic monitoring, in particular to an unmanned aerial vehicle-based 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 conge...

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, there are great limitations. Firstly, the expressway monitoring system cannot monitor the entire road section. Secondly, the police can manually capture pictures through video cameras and cameras. Although the entire road section can be captured, the efficiency is low. When encountering traffic jams, it is also impossible to capture pictures. Vehicles illegally occupying the road in front, therefore, an all-road, efficient and barrier-free new capture technology is urgently needed
