Based On The Video Vehicle Detection And Tracking And Positioning

According to the transportation of the video frequency examination with follow fixed position because of having good applied background,become studying at present of a hot point.The purpose of its research isn't to acquire the car discharge,conductor under the sistuation that does break road,car soon,etc.of the car model number transportation information,Provide science basis for macroscopic management and highway programming of road.Exercise in the dynamic state field view in the meantime the fast partition of object, The ray changes,having another vehicle mutually a chain etc.problem give according to the transportation of the video frequency examination with follow the research of fixed position brought a challenge.This text combines the analysis item of province Kunming City transportation appearance in Yunnan demonstration,taking in to study towards examining according to the transportation of the video frequency with following positioning,Put forward a better calculate way.The thesis divides 5 to elaborate to examine according to the vehicle of the video frequency with follow the research of fixed position:Examine according to the vehicle of video frequency currently of in the method,iner common use method:Reduces mutually and flow a method,background a bad cent only, this text compared the good and bad of[with]various method.Put forward the H S V space of from the orientation background model,discussed the establishment,judgment and renewal of the background model calculate way.Give in the meantime dean the way of doing of shadow.Discussed to use the processing of that method result,and gave calculate way flow chart.The target of aiming at sport follows with fixed position,introducing on the trail of calculate way to adopt in detail of expand the principle and the renewal calculate way of the filter of Kalman Filter;Analyzed currently this realm is various more popular method, compared good and bad.Then give Kalman Filter a wave to follow model,discuss a characteristic to be worth of withdraw,judgment,and follow the renewal calculate way of model.Gave result and structure diagram of processing finally.Experiment enunciation,according to the transportation of the video frequency examination with follow fixed position of H S V space of from orientation background model with expand Carl a Kalman Filter calculate way,have environment from orientation the ability is strong,computing quantity is small,examine accuracy is high, dependable practical advantage,can obtain without the vehicle information,car discharge statistics,average the car estimates etc.soon solid hour valid transportation parameter, while canning be made use of in actually environment,the background withdraws with renewal the calculate way have a possibility,examination with follow fixed position result also more ideal.Provide an important basis for the intelligence transportation system.
