The Infrared Image Enhancement And Target Detection And Tracking Technology

IR imaging guidance is the most wildly used among precise guidance technique and is one of application in military affairs of IR technique. The guidance system involved many areas such as IR physics, random signal processing, image analysis, high speed digital signal processing and so on. In them, the target detection, and tracking using the IR imaging technique is one of the symbol of modernization, intelligent, autoimmunization of modern weapon. It fulfills the mission of the lower s/n target detection and the precise tracking by use of real time process of IR image serial which input by detector. The main content in this paper is about the idiographic methods and research of IR image enhancement, target detection and tracking of IR imaging series and some achievements have been gotten.First, this paper discusses the basal characteristic of IR, the difference of radiation of target and background and the characteristic of infrared thermal imager. Then this paper concludes the characteristic of IR image and builds the academic foundation.In the facet of pre-transact of IR image, the traditional smooth spatial filter and histogram equalization are analyzed and intruded first. Then the research of image enhancement based on of Plateau equalization algorithm and Genetic Algorithm is done then in this chapter.Image segmentation with algorithm of 2D-maximal variance between-class and region growing is accepted to eliminate the background and the isolated noise points which can not be the target. The image after segmentation still has the noise and the other disturber, it is hard to detect by only one frame image. So the method by use of the relation by frame series is accepted to detect the true target.The function of tracking system is described in the facet of target tracking. The mechanism and implement condition are analyzed then. After the introduction of traditional algorithms, the algorithms of template matching is adopted to accomplish the target tracking and some emphases have been put on the field such as the first obtain template, the renovated template, the modified matching algorithms and the requirement of modification in the process of target tracking.
