Abstract

The invention discloses a wavelet algorithm based vehicle tracking recognition method. The method comprises the steps of S1, acquiring a real-time image; S2, updating the background of the image, and detecting an image difference portion by using a method of background subtraction; and S3, processing the image by using a wavelet algorithm, firstly performing binarization on the image, then performing expansion erosion treatment, then building an attitude optimization function by adopting the wavelet algorithm, performing location tracking so as to precisely capturing vehicle information location, and accurately tracking and recognizing a vehicle. According to the invention, a function of background updating is utilized, detection is performed on the foreground with great differences, and a background updating system is enabled not to be disturbed by small noises; feature recognition is performed, further identification is performed after the vehicle color is found out, and after a special vehicle is locked, the location of an intersection camera is utilized to act as the time so as to lock the vehicle; and various vehicles can be tracked at the same time, and the method can be applied to multi-intersection detection and real-time detection.

Description

technical field [0001] The invention relates to the field of computer application technology and image processing technology, in particular to a vehicle tracking and recognition method based on wavelet algorithm. Background technique [0002] Today's vehicles are a necessary means of transportation in daily life, so traffic safety is even more important. Now every household has at least one car, and only a few people do not have a car at home. Whether it is traveling, going to work, or taking children to and from school, they will use the car , because there are many vehicles, traffic safety is even more important, so computer vision is used as the basis to develop a vehicle monitoring system to assist monitors. The system will provide vehicle information on the road to monitors, replacing human eyes to observe road conditions for a long time, especially When a traffic accident occurs, if there is an escaped vehicle, the police can input the information of the escaped vehicl...
