Research And Achievement Of Traffic Information Arithmetic Based On Image Processing

The more and more traffic give us convenience, but give us series of questions at the same time, especially traffic jam. The most efficient way to solve traffic jam is to develop Intelligent Traffic System (ITS), and traffic information detecting is an important subject in ITS.This paper designs the system of traffic information detection according to the need of traffic information detection. The paper includes the constitutes of system hardware, image pretreatment, the achievement of parameter detection artithmetic.The main work is as follow:The pater makes use of vanguard genetic algorithms in image segmentation, uses vanguard genetic algorithms to get the image threshold. Using this method we may get different grey vehicles from the background exactly.Used the support vector machine theory to conduct the vehicles automatic sorting simulation research, the simulation result had proven this method could quite be accurate carries on the vehicles type the recognition;Improved based on the background automatic renewal hypothesized examination region algorithm, enhanced timeliness and the accuracy which the vehicles examines; And to has carried on the specify based on the hypothesized examination region imagery processing algorithm realization;In the paper also introduced withdraws the algorithm based on the gradation continuous movement vehicles characteristic to carry on the vehicles the characteristic to withdraw as well as to use the localization method which colored filter same gradation chart processing unifies to carry on the realization method which the vehicles license plate locates.In the end , the paper give the running result of the emulator, to make traffic flow, traffic speed, ect. show visually.
