The Research of Vehicle Tracking Based on Difference Screening and Coordinate Mapping
In order to identify vehicle driving cycle by monocular cam era an d t hen offer automotive active safety systems such as ACC (Adaptive Cruise Control) system, accurate condition identification signal, a difference screening method based on haar feature is put forward to identify the vehicle and a method based on coordinate mapping is improved to eliminate the impact that the changes of pitch angle make on the accuracy of positioning the vehicle, then combine with Karman filter technology to track vehicles. Finally, the studied method is used to track the vehicle in an actual video and the test results show that the method can correctly identify the image of vehicle, and accurately track the spatial position of vehicle. As a result, the studied method can be used to offer an active safety system like ACC accurate condition identification signal.
