Vehicle real-time tracking method and computer readable storage medium

Abstract

The invention provides a vehicle real-time tracking method and a computer readable storage medium, and the method comprises the steps: obtaining an image of each camera in a plurality of preset cameras, and obtaining a license plate region and license plate number information of a license plate of each vehicle in the image; performing coordinate conversion on the license plate region to obtain a first position of the vehicle in a world coordinate system; obtaining a second position of the vehicle in the real world through cooperative positioning of the plurality of cameras; and performing multi-camera cooperative tracking on the vehicle in real time based on the second position. By performing multi-camera cooperative positioning on the originally independent cameras, a more accurate vehicle position is obtained, so that multi-camera cooperative tracking is realized, and vehicle information is acquired in real time.

Description

Technical field[0001]The present invention relates to the field of computer visual techniques, and more particularly to a vehicle real-time tracking method and a computer readable storage medium.Background technique[0002]With the development of the economy, the amount of automobile usage in daily life is increasing, which makes the traffic control department have a lot of work, especially when regulating a certain or a few cars is required. Nowadays, the number of surveillance cameras is numerous to monitor the area of ​​some traffic flow. Even the entire area is surveillated with the camera's view coverage. If these cameras can be utilized, it will greatly improve supervision efficiency.[0003]In recent years, the rise of machine learning, deep learning, so that computer technology has developed rapidly, many of the cumbersome work to humans can be used efficiently, using computer processing, analyzing image information acquired by camera is a typical example.[0004]Regulating the ve...

AI Technical Summary

Problems solved by technology

The license plate detection and tracking technology is very mature now, but the existing technical solutions can only track the target in the current camera. When the vehicle leaves the current camera field of view and enters the field of view of a new camera, the tracking fails, even if the new camera re-performs the license plate detection, vehicle trajectories are also lost, which is not conducive to the supervision of identified vehicles

[0005] In the prior art, there is a lack of a technology to solve the problems of vehicle tracking failure and vehicle track loss when the vehicle moves across the camera
