Embodiment 1

[0041] This embodiment discloses an active vehicle continuous tracking and positioning system based on multi-data fusion. The system includes: a vehicle tracking detection sensor 1, a vehicle feature recognition device 2, and a roadside service platform 3. The vehicle tracking detection sensor 1 is set on Track and detect the passing vehicles on the side of the road, collect the original data information of all vehicles in the detection area through real-time scanning, and send them to the roadside service platform for real-time analysis and processing to obtain the preliminary data information of the vehicles, roadside service Platform 3 then processes, converts, and first fuses the preliminary data information of the vehicle with the map data in the area, obtains complete vehicle dynamic data information with latitude and longitude information, and starts the pre-set synchronous trigger data fusion rules for those entering the detection range. The vehicle is continuously trac...

Embodiment 2

[0056] This embodiment discloses an active vehicle continuous tracking and positioning method based on multi-data fusion, which is characterized in that the method is:

[0057] The vehicle tracking detection sensor 1 is set on the roadside to track and detect passing vehicles within the detection range, and collect the raw data information of all vehicles within the detection area by means of real-time scanning, and the raw data information is processed by the roadside service platform Vehicle preliminary data information;

[0058] The roadside service platform 3 analyzes and processes the map data in the area and the preliminary vehicle data information, filters out interference, integrates each other, superimposes and converts, obtains the real-time dynamic data of the vehicle in the area, and generates a complete vehicle dynamics with latitude and longitude information Data information and recorded as D1 data information;

[0059] After the vehicle tracking detection senso...

Abstract

The invention discloses an active vehicle continuous tracking and positioning system and method based on multi-data fusion. A vehicle tracking detection sensor of the system performs tracking detection on a vehicle; collected information is sent to a roadside service platform to be processed, so that vehicle preliminary data information is obtained; the vehicle preliminary data information is fused with regional map data, so that vehicle real-time dynamic information and a unique ID number can be generated; the vehicle enters a license plate snapshot triggering area; a vehicle feature recognition device acquires feature information of the vehicle, sends the feature information to the roadside service platform and calls a vehicle type and three-dimensional contour dimension data corresponding to the feature information, wherein the vehicle type and three-dimensional contour dimension data are pre-stored in a database; and the roadside service platform fuses the real-time dynamic information and the feature information of the vehicle and the Beidou\GPS clock time service information to generate complete vehicle identity information, starts physical space attributes to perform trajectory correction, and continuously outputs vehicle tracking and positioning data. According to the system and method of the invention, the vehicle running on the road can be continuously tracked and positioned without installing positioning equipment on the vehicle.

Description

technical field [0001] The invention relates to the technical fields of target tracking, behavior track analysis, inertial navigation, automatic driving, and automatic control, and in particular to an active vehicle continuous tracking and positioning system and method based on multi-data fusion. Background technique [0002] At present, the precise management of special vehicles on expressways is mainly to install vehicle-mounted GPRS or Beidou satellite positioning modules for these special vehicles to realize their positioning and abnormal behavior management. However, this technology is currently unable to achieve precise management of ordinary vehicles. In addition, the traditional positioning management system will lose its positioning function in special areas or tunnels, and cannot meet the application requirements of monitoring and management without dead ends throughout the process. The owner himself is inconvenient. [0003] On the expressway, it is necessary to ...
