Research On Moving Object Detection And Tracking Based On Video Surveillance Airport

With the development of the science and technology, all kinds of hi-techs are changing so quickly. In the field of the visual world, the detection and tracking of moving targets are worthy of studying. Just this aspect, it has attracted so many attentions from scholars all over the world. And many of them have already got lots of achievements. Even though the detection and tracking of moving targets are nearly in need of the using scenarios, it has many shortcomings when related to the scenario in this text. To begin with, instantaneity in airport security and protection, it is not suitable. Then, we all know that the environment of airport will be greatly effected by some natural factors, such as strong light. The next shortcoming is the number of the targets in the scenario. Therefore, this text pointed out a special scenario on the basis of the achievements, to have a further study of technology of the moving targets’ detection and tracking. The followings are study aspects:(1)The application of image preprocessing techniques are well studied, and the commonly used method in this paper an improved median filtering method of image preprocessing, the material for image de-noising, image enhancement, to enhance the information generated by the details, to suppress the noise.(2) To study the typical method of target detection, this paper studies the following algorithm: the optical flow method、the background subtraction method、the inter-frame different method. According to the specific scene and the actual situation, summarize the advantages and disadvantages of each method, this paper puts forward an advanced inter-frame different method and background subtraction method of target detection method.(3)To study the classic methods of target tracking, focuses on the following algorithm: based on the area of the tracking、based on feature tracking、based on the deformation of the template、based on the tracking of the model. And to summarize and analyze all these methods, according to the demand of the pointed scenario, it pointed out an improved detection method.(4) Done to the specific situation of the moving object in the scene four kinds of situation analysis, according to different circumstances, appropriate adjustments tracking method.Adopting the simulation method of MATLAB proposed in this paper, the simulation results show that the goal of this article detection and tracking technology has a good instantaneity, robustness and stability.
