Embodiment Construction

[0009] First, set up a fixed video capture device in the area to be monitored, collect the video of the vehicle in the monitored area, connect the video to the background server for processing, and identify the passing license plate number in real time. The steps of the license plate recognition system: (1) video acquisition; (2) image preprocessing; (3) license plate location; (4) character segmentation; (5) character recognition;

[0010] Second, save the recognized license plate number into the database;

[0011] Third, compare the real-time recognized license plate number with the license plate number stored in the database. If the same license plate number has been stored in the database, it indicates that the vehicle has an abnormal trajectory around the monitoring area or facility.

Abstract

A method for identifying an abnormal track of a vehicle through video monitoring comprises the following steps: (1) arranging a fixed video acquisition device in an area to be monitored, acquiring a video of the vehicle in the monitored area, accessing the video to a background server for processing, and identifying a license number of the passing vehicle in real time; (2) storing the identified license number in a database; (3) comparing the license number identified in real time with the license number stored in the database, and if the same license number is stored in the database, determining that the track of the vehicle is abnormal in the area.

Description

Technical field [0001] The invention relates to the field of public security video intelligent monitoring, and relates to the application of video intelligent monitoring technology, pattern recognition technology and image processing technology. Background technique [0002] At present, image processing and pattern recognition technology have been widely used in traffic monitoring, and license plate recognition is a relatively basic work. For some more important places or facilities, we also pay attention to the abnormal trajectory of the surrounding vehicles. The abnormal trajectory mainly refers to abnormal circles. Vehicle abnormal trajectory analysis methods currently include GPS monitoring methods and video monitoring methods. GPS monitoring methods need to obtain real-time GPS position information of the vehicle and analyze it as a trajectory point. Video surveillance technology is divided into target recognition tracking monitoring and license plate recognition, which inv...
