determining a preset specific implementation class corresponding to each identification camera according to the storage structure body, and starting a license plate identification thread corresponding to the identification cameras according to the specific implementation class;
triggering license plate recognition events under the condition that a vehicle enters a defense arrangement area of a corresponding recognition camera, so as to call a corresponding manufacturer recognition SDK through a license plate recognition thread of the corresponding recognition camera, and acquire vehicle license plate information;
and sending the acquired license plate information of the vehicle to the front end of the system.
10. A multi-vendor identification camera integrated compatible non-volatile computer storage medium storing computer executable instructions, the computer executable instructions configured to:
introducing license plate recognition control at the front end of the system; the license plate recognition control is used for controlling dynamic connection files corresponding to the recognition cameras;
the front end of the system acquires camera connection information of each identification camera based on the license plate identification control, and sends the camera connection information to the rear end of the system;
dividing the camera connection information at the rear end of the system, and storing the divided camera connection information into a preset storage structure;
determining a preset specific implementation class corresponding to each identification camera according to the storage structure body, and starting a license plate identification thread corresponding to the identification cameras according to the specific implementation class;
triggering license plate recognition events under the condition that a vehicle enters a defense arrangement area of a corresponding recognition camera, so as to call a corresponding manufacturer recognition SDK through a license plate recognition thread of the corresponding recognition camera, and acquire vehicle license plate information;
