Problems solved by technology

Since such a tracking algorithm is based on vehicle detection, its real-time performance is poor.
The target tracking algorithm needs to specify the target to be tracked, which requires the driver to continuously specify the target to be tracked, which will seriously affect the driver, but the real-time performance is high

Embodiment 1

[0037] The switching method of the vehicle detection and tracking mode in this embodiment can be switched between the two modes of vehicle detection and vehicle tracking, so that during the vehicle detection process, if the driver wishes to track certain vehicles, if he is not familiar with the driving route, he must When there is a vehicle leading the way or the police need to track the suspect's vehicle, the system will send the data of the target vehicle to be tracked to the tracking part for tracking.

[0038] At the same time, the switching method described in this embodiment can also be used to evaluate the detection results by the system when the driver does not request tracking. If the detection results are considered to be effective, it will automatically switch to the tracking mode. After tracking a certain number of frames, restart Switch to detection mode to detect new vehicles entering the video.

[0039] The specific implementation process of the above method is ...

Abstract

The invention discloses a method for switching vehicle detection and tracking modes. The method includes the following steps: (1), detecting and marking vehicles in videos; (2), numbering the marked vehicles and recording information of the vehicles; (3) if drivers require to track the vehicles, switching into a tracking mode; (4), if the drivers do not require to track the vehicles, judging whether more than three complete vehicles are detected in current videos or not, if yes, entering step (5), and if not, returning step (1); (5), automatically entering a vehicle tracking mode, and returning step (1) after a plurality of continuous frames are processed or targets are lost. Compared with the prior art, the method has the advantages that by the method, vehicle detection and vehicle tracking can be realized, and tracking of specific vehicles according to requests of the drivers and automatic tracking of detection targets according to detection results also can be realized, so that vehicle detection and vehicle tracking are combined, instantaneity of a vehicle detection and tracking algorithm is greatly improved, and needs of the drivers are met.

Description

technical field [0001] The invention relates to the field of vehicle detection and tracking technology research, in particular to a method for switching vehicle detection and tracking modes. Background technique [0002] With the development of society and the continuous improvement of people's living standards, automobiles have gradually become popular. However, the trend of traffic accidents, especially vicious traffic accidents, is on the rise. In recent years, the growth rate of vehicles has been far higher than that of roads and other traffic facilities. Therefore, traffic accidents continue to occur, casualties are increasing day by day, and property losses are serious. [0003] The main causes of traffic accidents are speeding, lane-occupied driving, drunk driving, and fatigue driving. It can be seen that most of the causes of traffic accidents are the subjective reasons of drivers when driving. Studies have shown that if the driver can be warned about 0.5 seconds ...
