Problems solved by technology

However, many traffic safety problems that follow have become increasingly prominent, among which illegal parking on expressways is a major safety hazard
At present, the supervision of highway vehicle driving still requires a lot of manpower and material resources. In addition, the traffic flow of vehicles on holidays is large enough to attract attention, especially the weather conditions that are not conducive to travel such as heavy fog will increase the probability of accidents on highways.

Embodiment 1

[0033] Example 1: Such as figure 1 As shown, a method for detecting illegal parking on highways. First, extract video sequences and encode and identify highways in the area to establish a video sequence information database for the highway section; secondly, perform image processing on the road section video sequence to extract motion The vehicle license plate is marked with the center of mass of the vehicle, the distance between the center of mass of the vehicle and the initial position of the expressway in the area is recorded, and a real-time position information database of the vehicle is established for storage; then, the vehicle is tracked and calibrated to determine the distance between the vehicle and the initial position in the video sequence Change, judge the driving state of the vehicle, and calculate the illegal parking time of the vehicle; finally, according to the length of time the vehicle has illegally parked on the section of expressway, a parking warning is iss...

Abstract

The invention relates to a highway illegal parking detection method, belonging to the technical field of image processing. According to the method, firstly, a highway in an area is subjected to video sequence extraction and code identification, and a high speed road video sequence information base is established; secondly, the road video sequence image processing is carried out, a moving vehicle license plate is extracted and the center of mass of a vehicle is calibrated, the distance from the center of mass of the vehicle to a highway initial position in the area is recorded, and a vehicle real-time position information base is established and stored; then a driving vehicle is subjected to tracking calibration, the change rate of the vehicle to the initial position in the video sequence is judged, a vehicle driving state is judged, and the illegal parking time of the vehicle is calculated; and finally an illegal parking warning is emitted according to the illegal parking time length of the vehicle at the highway. According to the method, a designated road can be subjected to real-time monitoring, vehicle illegal parking can be timely found, potential traffic accidents can be avoided, the accuracy of illegal parking early warning is greatly raised, and the consumption of manpower resources is reduced.

Description

Technical field [0001] The invention relates to a method for detecting illegal parking on expressways, which belongs to the technical field of image processing. Background technique [0002] With the development of the information age, people's living standards have gradually improved, and motor vehicles have become a means of transportation for more people to travel. However, many traffic safety problems that follow have become increasingly prominent, among which illegal parking on expressways is a greater safety hazard. At present, the supervision of highway vehicle driving still requires a lot of manpower and material resources. In addition, the large traffic volume of vehicles on holidays is enough to attract attention, especially the unfavorable weather conditions such as heavy fog will increase the probability of highway accidents. Therefore, how to efficiently and accurately detect vehicle driving on a road section has become an urgent problem to be solved. Highway parki...
