Embodiment Construction
[0051]The core of the invention is to provide a vehicle tracking method based on the analysis of the intermodulation index of the overtaking control station. In the prior art, usually by shooting a video of the target road section, the video stream is processed through a neural network, and the speed of each vehicle is tracked and analyzed as the average speed of the vehicle. However, the existing vehicle tracking programs often use the correlation between front and rear frames, which cannot effectively track long-distance vehicles and vehicles whose view is blocked, and the range and traceability of vehicle tracking are poor. When the camera is far away and the image resolution is low, it is difficult to distinguish the same car at a distance. At the same time, because the nearby vehicles occupy a large proportion of the video screen, there are many cases where the front car blocks the rear car. A car from a distance It is difficult to guarantee a complete record of the whole...

The invention discloses a vehicle tracking method based on the analysis of the intermodulation index of the overtaking control station, which includes obtaining the video stream of the target road section through the camera; calling the YOLO model to identify the video stream, and generating the positioning frame of each vehicle in the corresponding video stream; The positioning frame is preprocessed, and the trajectory information is generated according to the positioning frame that meets the preset conditions; the vehicle image includes the target vehicle; the trajectory information of the target vehicle is identified, and when the trajectory of the target vehicle is interrupted in the target road section, it corresponds to the trajectory information of the same target vehicle . Firstly, the trajectory information of each vehicle is generated based on the video stream, and then each trajectory information is retrieved based on the vehicle image captured at the weighing platform, and the trajectory information corresponding to the same vehicle is merged and completed, which can effectively improve the robustness of vehicle tracking data. The present invention also provides a vehicle tracking device, a vehicle tracking device and a computer-readable storage medium, which also have the above beneficial effects.
Description
technical field [0001] The present invention relates to the technical field of image recognition, in particular to a vehicle tracking method based on the analysis of cross-regulation indicators at overtaking control stations, a vehicle tracking device based on the analysis of cross-regulation indicators at overtaking control stations, and a vehicle tracking device based on the analysis of cross-regulation indicators at overtaking control stations. An analyzed vehicle tracking device and a computer readable storage medium. Background technique [0002] In order to facilitate the traffic authorities to grasp the road traffic operation situation in a timely and comprehensive manner, so as to provide a basis for road network management and decision-making, it is necessary to investigate and evaluate various indicators such as the congestion situation and operation quality of various roads. The intermodulation data is the data used by the competent traffic authorities. The interm...
