Problems solved by technology

At present, bullet cameras are usually used to monitor the parking lot. Due to the large area of ​​the parking lot, it is impossible to recognize the license plate of the vehicle with a long distance and a remote view; when using a smart dome camera to monitor the vehicles in the parking lot, the smart dome The FOV (Field Of View, coverage) of the camera is small
When the smart dome camera captures the license plate, it cannot monitor the vehicles in the parking lot
[0003] In summary, using the above methods to monitor the vehicles in the parking lot will cause potential safety hazards

Embodiment 1

[0041] figure 1 It is a flow chart of the license plate recognition method based on the compartment state provided by Embodiment 1 of the present invention.

[0042] refer to figure 1 , the execution subject is a bullet camera, and the method includes the following steps:

[0043] Step S101, acquiring the position and running track image of the vehicle;

[0044] Specifically, according to the position of the vehicle at different times, and using a tracking algorithm, the vehicle's position and running track image is obtained.

[0045] Step S102, the vehicle's position and running trajectory image is obtained through a deep learning algorithm to obtain the vehicle's compartment state information;

[0046] Step S103, according to the state information of the carriage, obtain the position information corresponding to the vehicle;

[0047] Specifically, the vehicle's position and running trajectory image is input into the deep learning algorithm, and the vehicle's compartment ...

Embodiment 2

[0060] image 3 It is a schematic diagram of the license plate recognition device based on the state of the compartment provided by Embodiment 2 of the present invention.

[0061] refer to image 3 , the device includes: a running trajectory acquisition unit 1 , a compartment state acquisition unit 2 , a vehicle position information acquisition unit 3 and an identification unit 4 .

[0062] Running trajectory acquisition unit 1, used to obtain the position running trajectory image of the vehicle;

[0063] The carriage state acquisition unit 2 is used to obtain the carriage state information of the vehicle through the deep learning algorithm through the position running track image of the vehicle;

[0064] The vehicle position information acquisition unit 3 is used to obtain the corresponding position information of the vehicle according to the compartment state information;

[0065] The recognition unit 4 is used to send the corresponding position information of the vehicle...

Abstract

The invention provides a vehicle license plate recognition method and device based on a carriage state, which are applied to a gun-type camera and comprise the following steps: acquiring a position moving track image of a vehicle; performing a deep learning algorithm on the position moving track image of the vehicle to obtain compartment state information of the vehicle; obtaining position information corresponding to the vehicle according to the carriage state information; and sending the position information corresponding to the vehicle to the intelligent ball camera, so that the intelligentball camera positions the vehicle according to the position information corresponding to the vehicle and identifies the license plate of the vehicle, the license plate can be effectively identified,the vehicle can be effectively monitored, and the monitoring safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle identification, in particular to a vehicle compartment state-based license plate identification method and device. Background technique [0002] The intelligent and unmanned monitoring and management of the parking lot has important application value and social benefits. At present, bullet cameras are usually used to monitor the parking lot. Due to the large area of ​​the parking lot, it is impossible to recognize the license plate of the vehicle with a long distance and a remote view; The FOV (Field Of View, coverage) of the camera is small. When the smart dome camera captures the license plate, it cannot monitor the vehicles in the parking lot. [0003] To sum up, monitoring the vehicles in the parking lot by the above method will cause potential safety hazards. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a license plate recognition...
