Long-term side-by-side driving recognition method and system on expressway

Abstract

The invention discloses a method and system for identifying long-term side-by-side driving on expressways. The method includes the following steps: (1) acquiring the video collected by the driving recorder and decoding it into continuous frame pictures; (2) identifying the The license plate color and license plate image of different vehicles in front; (3) Calculate the distance between the driving recorder and different vehicles in front based on the recognized license plate color and the area of ​​the license plate image, the area of ​​the entire frame picture, and the internal fixed parameters of the camera; (4) Calculate The difference between the distance between the driving recorder and the vehicle in front at different times to identify whether there is a vehicle in front driving side by side for a long time. The recognition method and system of the invention can save a lot of manpower, improve the recognition efficiency, and have a high coverage rate at the same time.

Description

technical field [0001] The invention relates to a recognition method and system for parallel driving, in particular to a recognition method and system for long-term vindictive parallel driving on expressways. Background technique [0002] my country's expressways are developing rapidly, and the expressway mileage ranks first in the world. However, if the two cars run side by side for a long time, it is easy to disperse the driver's attention from the front to the left and right, causing nervousness and greatly increasing the probability of accidents. At the same time, it will seriously affect the overtaking of the vehicles behind, causing consequences such as traffic jams. Existing methods for detecting long-term side-by-side driving are manual detection and video detection. Manual detection is generally taken by drivers or traffic police using mobile phones. However, it is a traffic violation for a driver to use a mobile phone to take pictures while driving, which limits...

AI Technical Summary

Problems solved by technology

However, it is a traffic violation for a driver to use a mobile phone to take pictures while driving, which limits the role of the traffic violation reporting platform to a certain extent

However, taking pictures by the traffic police requires a lot of manpower and material resources

The video detection is generally fixed-point detection, such as the illegal camera installed by the traffic control department on the expressway, which is expensive and has low coverage, and the camera itself does not have the function of illegal detection, and still needs manual intervention
