Vehicle window throwing object detection method based on real-time video

Abstract

A vehicle window throwing object detection method based on a real-time video comprises the following steps: acquiring and decoding a video stream, processing each decoded frame of image by using the relevance of front and back frames in a video image sequence so as to detect the moving target areas of all images, extracting the moving target areas, tracking the extracted moving target areas, and finally, judging whether the moving target is a vehicle window throwing object or not according to the inherent position, size and motion characteristics of the thrown object, and if the moving targetis judged to be the vehicle window throwing object, identifying the license plate of the vehicle which throws the object. According to the invention, the vehicle window throwing object behavior in themonitoring video can be detected without human participation, the real-time performance can be ensured, the detection accuracy can be ensured, the license plate of the vehicle with the vehicle windowparabolic behavior can be identified, efficient and large-scale all-weather real-time monitoring can be achieved, time and labor are saved, and the problem of difficult management is solved.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a real-time video-based window parabola detection method. Background technique [0002] At present, with the rapid development of the economy, the use of cars is becoming more and more common, and various bad habits of driving and riding in cars are also emerging, such as throwing paper towels, mineral water bottles and other garbage from the car windows. Window throwing behavior not only destroys the appearance of the city, pollutes the urban environment, and affects traffic safety, but also most of the garbage thrown from the window is left on the motorway, which seriously threatens the life safety of sanitation workers. [0003] How to control the uncivilized behavior of car window parabolic behavior has become a difficult problem that city managers must face.

[0002] At present, with the rapid development of the economy, the use of cars is becoming more and more common, and various bad habits of driving and riding in cars are also emerging, such as throwing paper towels, mineral water bottles and other garbage from the car windows. Window throwing behavior not only destroys the appearance of the city, pollutes the urban environment, and affects traffic safety, but most of the garbage thrown from the window is left on the motorway, which seriously threatens the life safety of sanitation workers

[0003] How to control the uncivilized behavior of car window parabolic behavior has become a difficult problem that city managers must face. At present, it mainly relies on manual video surveillance to detect car window parabolic behavior. This method is time-consuming and laborious, with limited coverage and detection time gaps. Unable to realize efficient and large-scale all-weather real-time monitoring
