The specific embodiment of the present invention applied to the device is substantially the same as the following embodiments of the target area vehicle monitoring method, and will not be described herein again.
An embodiment of the invention provides a target area vehicle monitoring method, and referring to fig. 2, fig. 2 is a schematic flow chart of the target area vehicle monitoring method embodiment of the invention.
In this embodiment, the target area vehicle monitoring method is used for a target area vehicle monitoring device, and includes the following steps:
and step S100, when the target vehicle is detected to enter the target area, acquiring the state information of the target vehicle and the vehicle density of the target area.
Specifically, in the present embodiment, the state information includes speed information and acceleration information of the target vehicle, and the vehicle density of the target area is the number of cameras that perform the collection task.
And S200, determining a camera linkage distance based on the state information and the vehicle intensity.
Specifically, in the present embodiment, the camera linkage distance is determined based on the state information and the vehicle density, and the camera linkage distance may be determined by the number of cameras that are performing the acquisition task in the target area based on the speed information and the acceleration information of the target vehicle.
Furthermore, based on the speed information and the acceleration information of the target vehicle and the number of cameras executing the collection task in the target area, an expression of the camera linkage distance is determined, specifically:
s=|k×v×a×c|
wherein s is a camera linkage distance, v is speed information of the target vehicle, a is acceleration information of the target vehicle, c is the number of cameras executing the acquisition task in the target area, and k is a constant.
It should be noted that, since the speed and the acceleration of the target vehicle in the target area and the number of vehicles in the target area all affect the occurrence of traffic accidents and disputes, when determining the camera linkage distance, the present embodiment considers the speed information and the acceleration information of the target vehicle and the number of vehicles in the target area, where the number of vehicles in the target area is measured by the number of cameras in the target area that are executing the collection task. That is, the faster the running speed of the target vehicle in the target area, the higher the acceleration, and the more vehicles in the target area, the larger camera linkage distance is dynamically generated, and further, the more target cameras for monitoring the target vehicle are determined by the camera linkage distance, so that more comprehensive, perfect, and different-angle monitoring data are provided for the target vehicle.
And step S300, acquiring current position information of the target vehicle, and determining the target camera according to the current position information and the camera linkage distance.

And in the comparison table of the position information and the terminal monitoring coefficient, the position information corresponding to the road narrow area and/or the accident-prone area has a higher key monitoring coefficient. Therefore, the expression for correcting the linkage distance of the camera is specifically as follows:
s’=s×i
and s' is the corrected linkage distance of the camera, s is the linkage distance of the camera, and i is a key monitoring coefficient corresponding to the current position information.
In this embodiment, after the current position information is obtained, the camera linkage distance is corrected according to the key monitoring coefficient of the current position, and after the camera linkage distance is obtained, the linkage monitoring coordinate region of the target vehicle can be determined according to the camera linkage distance and the current position information of the target vehicle, where the coordinate region is usually circular, that is, when the target vehicle travels in the target region, only the camera in the linkage monitoring coordinate region range is determined as the target camera.

Therefore, independent monitoring videos of each vehicle passing through a target area are stored in a database of the monitoring system, the independent monitoring videos are automatically synthesized by monitoring videos collected by a plurality of target cameras, and monitoring pictures collected by a plurality of target cameras at the same position can be displayed in a split screen mode within the simultaneous collection time range. According to the embodiment, the independent monitoring video of the target vehicle passing through the target area is generated, so that the efficiency of monitoring video viewing is improved, and more comprehensive and complete monitoring data are provided for traffic accidents or disputes in the target area.
