Embodiment 1
[0034] figure 1 It is a flow chart of the method for tracking a target described in this embodiment. This embodiment is applicable to the situation of automatically delineating and tracking a checkpoint warning vehicle. means of tracking targets to perform, such as figure 1 As shown, the method for tracking a target described in this embodiment includes:
[0035] Step S101. Obtain the alarm information of the checkpoint point, the alarm information includes the identification of the checkpoint point for the alarm, the speed and the driving direction of the vehicle detected at the checkpoint point at the time of the alarm.
[0036] Checkpoints refer to the entrances and exits from the periphery of the city. Checkpoints are installed at the entrances and exits of urban areas to monitor traffic conditions. Generally, they are mainly used for license plate recognition, speeding capture, and illegal vehicle capture. They are mainly used in non-compliant areas. Alarm when vehicles...
Embodiment 2
[0061] On the basis of Embodiment 1, this embodiment is based on the fact that when an alarm event occurs at a bayonet point, only image capture, speed measurement, and direction determination are performed on the vehicle at the location of each bayonet point. Data acquisition work such as Condition, figure 2 is the flow chart of the method for tracking the target described in this embodiment, as figure 2 As shown, the method for tracking a target described in this embodiment includes:
[0062] Step S201, monitoring vehicle information at each checkpoint.
[0063] If the checkpoint points laid out on the traffic network are only used for data acquisition such as image capture, speed measurement, and direction determination of vehicles at the entrances and exits of the urban periphery, dangerous roads, and key road sections, etc. , without any analysis and processing, the camera used to shoot the surveillance video needs to monitor the vehicles passing through each bayonet ...
Embodiment 3
[0076] image 3 is a structural block diagram of the device for tracking a target described in this embodiment, such as image 3 As shown, the device for tracking a target described in this embodiment includes:
[0077] The alarm information acquisition unit 310 is used to acquire the alarm information of the bayonet point, and the alarm information includes the bayonet point identification of the alarm, the speed and the driving direction of the vehicle detected by the bayonet point at the time of the alarm;
[0078] The alarm point coordinate acquisition unit 320 is used to lock the checkpoint point from the video screen according to the checkpoint point identification, and obtain the screen coordinates of the checkpoint point;
[0079] The suspicious vehicle delineation and tracking unit 330 is configured to delineate the suspicious vehicle according to the screen coordinates, and track the suspicious vehicle according to the speed and the driving direction.
[0080] Furt...
