Embodiment 1

[0027] This embodiment discloses an active vehicle continuous tracking device, which is characterized in that the vehicle continuous tracking device includes: a radar sensor, a vehicle capture camera 1, a data acquisition processor 2, and the radar sensors are arranged at equal intervals on the road side On the side or in the middle of the road, the vehicle capture camera 1 is set above the lane, and a corresponding number of vehicle capture cameras 1 are set according to the number of lanes. The data acquisition processor 2 is installed at the same point as the radar equipment and installed on the side of the road. The edges are respectively connected to the radar sensor and the vehicle capture camera 1 through the network. The radar sensor collects the raw data of all stationary and moving targets in the radar detection area by scanning, and sends it to the data acquisition processor 2 for processing. The vehicle dynamic data is obtained by data analysis and processing, and th...

Embodiment 2

[0032] This embodiment discloses an active vehicle continuous tracking system, which is characterized in that the system includes: a vehicle occlusion tracking compensation module, a radar data processing synchronization trigger capture module, a vehicle ID identification number correction module, and a vehicle continuous tracking information transfer interaction Module, vehicle complete data information loss, secondary calibration information backtracking module, dynamic information and feature information binding and fusion module, the vehicle occlusion tracking compensation module is based on the change rule of the first five point trace information of the vehicle’s self-lost information after the radar scan The current movement law of the vehicle and the logic of inertial navigation are used to simulate point traces and dynamic information compensation. When the vehicle is in the vehicle occlusion area 5 and cannot be effectively scanned by the radar and obtain the dynamic in...

Embodiment 3

[0045] This embodiment discloses an active vehicle continuous tracking method, which is characterized in that the method is: using a radar sensor to collect raw data of all stationary and moving targets in the radar detection area, and send it to the data acquisition processor 2 Carry out data analysis and processing to obtain vehicle dynamic data, and follow the pre-set rules to track and monitor vehicles entering the radar detection range, and generate a unique ID number corresponding to the vehicle.

[0046] After the vehicle capture camera 1 is connected to the data acquisition processor 2, when the radar sensor detects that a vehicle enters the preset trigger capture area 3, the data acquisition processor 2 will carry the unique ID number corresponding to the vehicle The dynamic tracking information is used as a trigger signal and is sent to the vehicle capture camera 1 corresponding to the trigger area for synchronous trigger capture. The captured pictures are numbered by th...

Abstract

The embodiment of the invention discloses an active vehicle continuous tracking and positioning device, system and method. The vehicle continuous tracking device comprises: a vehicle continuous tracking unit; a radar sensor, a snapshot camera and a data processor, the radar sensor scans and acquires original data in a detection range; dynamic data and a unique ID number of each vehicle are formedafter the data is processed by the data processor; when the radar tracks the vehicle to enter a preset area; the data processor acquires information and synchronously triggers the snapshot camera to capture a vehicle image and send the vehicle image to the data processor to acquire vehicle feature information; the data processor associates and fuses the dynamic data and the characteristic data ofthe same vehicle according to a rule, and starts a data cross-radar handover mechanism when the vehicle enters an adjacent radar overwrapping area, thereby realizing a function of tracking and positioning the same vehicle in the whole process within a plurality of radar coverage ranges. According to the invention, the problems that highway vehicles cannot realize whole-course active tracking and positioning, the positioning is inaccurate, the information is incomplete, and the tracked vehicles are easy to lose are solved.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of target tracking and behavior trajectory analysis, and in particular to an active continuous vehicle tracking device, system and method. Background technique [0002] On highways, it is necessary to monitor the speed and driving status of the driving vehicles, and collect basic information of the car. The existing license plate capture system is mainly triggered by external or self-triggered two working methods to realize the image capture function of the vehicle. The triggering mode is mainly realized by: coil vehicle detector, speed measuring radar sensor, multi-target radar sensor, lidar sensor, etc. When the vehicle passes the detection area pre-drawn by the above detector, the sensor will capture the license plate camera And the trigger signal (usually the IO control amount), the license plate capture camera will activate its own camera shutter to capture the image of the vehicle ...
