Research On Video Traffic Flow Background Extraction And Moving Target Track And Detection Technology

In recent years,countries around the world have established extensive transportation network,The growth of vehicles and roads and other transport facilities,has caused a series of traffic problems,such as huge material and economic loss,to solve the issue effectiveness is very limited only depends construction of roads and other transport facilities.For the order unobstructed,safe,quick moving of the transportation,the organic fusion among the traffic flow monitoring,management and evacuation appears very necessary.And So,it is to be a important premise of the system realization and a key point of the thesis study about computer video detection technology study.of the Intelligent Transportation Systems(ITS)..The application of computer vision technology to traffic detecting and information collecting is animportant subject in ITS,and extraction of the background model and updated and moving vehicle detecting,recognition and tracking is the basic part.To the above problems,the further study is done in this thesis and newmethods are brought forward.Moreover,experiments are implemented to demonstratethe validity.This thesis is a full integration system research between information technology and traffic engineering system,too.It has been using the theoretical analysis and research to engineering practice means,and using the existing traffic flow parameters' detector to study how to choice the hardware and the detection algorithm.This thesis designed the system's frame and model.The thorough research of various parameters detection algorithm has been conducted,and compiled the code to carry on the examination,from two aspects of the algorithm efficiency and effectiveness to improve and optimize the algorithm until the system to achieve real-time requirements.Mainly algorithm includes:based on statistical model background extraction and renewal algorithm;moving target area integration algorithm; moving target shadow elimination algorithm;based on the target match's vehicles track algorithm and so on a series of algorithms.On the above algorithm's foundation,the traffic flow parameters extraction was realized.Ultimately,video-based traffic flow parameters detection system was developed and realized,and it has achieved the design requirements after testing,the system in the technical realization reach the primary goal,too.
