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

Embodiment Construction

[0074] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0075] The invention is aimed at the expressway emergency lane, the lane line of which conforms to the national normative standard, and the brightness difference between the lane line area and the road surface area is relatively large.

[0076] Such as figure 1 As shown, a method for detecting illegal occupancy of emergency lanes based on the lane line model includes the following steps:

[0077] S1, constructing the lane line model, the method is first to find the maximum width of the lane line in the current frame highway video image, and scale according to the scaling factor s, refer to figure 2 Construct the lane line model, where W s The value of is equal to 0.7 times the maximum width of the lane line after scaling.

[0078] Such as figure 2 As shown, the lane line model is a width of 5W s , the height is W s A rectangular area co...

Abstract

The present invention provides a method for detecting illegal occupation of emergency lanes based on a lane line model, comprising: constructing a lane line model; acquiring a current frame road image; acquiring a current frame road binary image; detecting the position of a lane line; determining the type of a lane line edge ; Determine the straight line position of the edge of the candidate emergency lane line; determine the straight line position of the edge of the emergency lane line in the current frame; determine the area of ​​the emergency lane; detect vehicles that illegally occupy the emergency lane; perform license plate recognition on the detected vehicles; The invention adopts the video image analysis technology to accurately locate the emergency lane area in real time, and automatically captures the vehicles appearing in the emergency lane area.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic monitoring, in particular to a detection method for illegally occupying an emergency lane based on a lane line model. 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 congest...
