Unmanned aerial vehicle-based illegal emergency lane occupancy detection method

Abstract

The invention provides an unmanned aerial vehicle-based illegal emergency lane occupancy detection method. The method comprises the following steps: sending out an unmanned aerial vehicle; positioning a road right edge position; judging whether the road right edge position is positioned; adjusting the orientation of the unmanned aerial vehicle; selecting an emergency lane area; detecting a vehicle position; judging whether the vehicle position is successfully detected; recognizing vehicle license plate characters; storing vehicle information; correcting the fleet angle of the unmanned aerial vehicle; enabling the unmanned aerial vehicle to advance automatically; judging whether the unmanned aerial vehicle flies to an appointed distance; and withdrawing the unmanned aerial vehicle. The method provided by the invention is capable of realizing the automatic flight control of the unmanned aerial vehicle, ignoring any traffic barrier, accurately positioning the emergency lane areas in real time through a video image analysis technology and automatically snapshooting the vehicles in the emergency lane areas, and has the characteristics of realizing all-section snapshooting and being real-time, efficient and accurate in snapshooting and free of barrier.

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
