Embodiment 1

[0033] Embodiment 1 provided by the present invention is an embodiment of a method for accurately locating a checkpoint passing a vehicle. In step 1, the electronic fence has a radiation radius, and the bayonet camera is associated with the electronic fence according to the radiation radius, and the bayonet camera and the associated electronic fence are determined. A bayonet camera is associated with a geo-fence, and a geo-fence is associated with one or more bayonet cameras.

[0034] In the embodiment of the present invention, according to the passing information of the same vehicle captured by one or more bayonet cameras, the number of times the same vehicle captured by the one or more bayonet cameras passing through the electronic fence associated with each bayonet camera can be calculated respectively. At any time, the intersection analysis operation is performed on the mobile phone information obtained by one or more associated electronic fences at the corresponding time, ...

Embodiment 2

[0043] The second embodiment provided by the present invention is an embodiment of the system for accurately positioning the bayonet passing the vehicle, such as image 3Shown is the schematic diagram of the structure of the system, which consists of image 3 It can be seen that the system includes electronic fence management module, intelligent traffic management module and correlation analysis module.

[0044] The intelligent traffic management module obtains the vehicle passing information obtained by the bayonet camera, and the passing information includes the vehicle speed and passing time.

[0045] The electronic fence management module acquires the mobile phone information of the drivers and occupants of vehicles passing through the electronic fence at various times.

[0046] The bayonet camera is associated with the electronic fence, and the association analysis module determines the time T when the vehicle passes through the associated electronic fence according to t...

Abstract

The invention belongs to the technical field of vehicle positioning, and provides a method and system for accurately positioning a vehicle passing a checkpoint. The method includes the steps that the incidence relations between a checkpoint camera and electronic fences are configured according to distance and position information of the checkpoint camera and the electronic fences; the checkpoint camera obtains vehicle passing information of the vehicle, and the vehicle passing information includes the speed of the vehicle and the vehicle passing moment; according to the speed of the vehicle and the distance between the checkpoint camera and the related electronic fence, the moment T when the vehicle passes through the related electronic fence is determined; according to mobile phone information obtained according to the electronic fence related to the moment T, the vehicle is positioned. Existing mature system frameworks in the intelligent transportation field and the electronic fence field are combined, and the checkpoint camera and the electronic fences are related, so that the mobile phone information of a vehicle driver and a passenger is obtained to position the vehicle, the accurate positioning information of the vehicle can be obtained in real time without newly building an information collecting system, and the obtaining process is simple and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of vehicle positioning, and in particular relates to a method and a system for accurately positioning a bayonet passing vehicle. Background technique [0002] As the public security situation becomes more and more serious, the public security system is facing more and more challenges. Public security personnel urgently need more convenient and accurate data analysis support to meet the challenges. In the field of intelligent transportation, a group of suspicious vehicle data was captured. The public security system needs to analyze various aspects of vehicle and personnel related information for location tracking or filtering. [0003] In the technical solution disclosed in the utility model patent (Application No.: 201220382061.5) titled "A Vehicle Positioning System Based on Monitoring Bayonet", the data collected by the front-end capture device is sent to the positioning platform through the transmission ...
