Infrared Image Target Detection, Identification And Tracking Technology Research

With the development of precision guided weapons, the requirements on information processing techniques for precision guidance is becoming higher and higher. This has become a key factor, which restricts the development of the weapon. Since IR imaging guidance possesses many advantages, it has become the trend and direction for current development and study of precision guidance technologies worldwide. On the basis of the fundamental characteristics of IR imaging guidance, the current development status of guidance information processing methods, the main problems existed as well as the basic requirements on its practical engineering applications, this paper has made systematic in depth studies on various aspects as preprocessing of IR images, target image segmentation , target recognition and target tracking. The main achievements of this paper are as fellows:(1)The thermal imaging theory and the characteristics of infrared image are analyzed in this dissertation. Image histogram is mainly discussed and an interlace row/column histogram statistic method is proposed. Based on histogram research, two novel image enhancement algorithms are put forward. It is adaptive piecewise linear transform.(2)A Wavelet edge detection method which is self-adaptive, multi -scale and anti-jamming has been studies for use in formation processing for IR imaging terminal homing guidance. By means of multi-resolution analysis concept for auto-zooming of wavelet transformation, a multi-resolution Gaussian gradient operator which is suitable for noisy edge detection is configured .The experiment results show that this method is an automatic rapid and effective target detection method.(3)ATR is studied in this paper both invariant moments to round degree. And , against the helicopter the result of test is given. The idea of topological is introduced in the fried of ATR, the hitting-point choice on the basis of characteristic points is studied and aiming at the tanker a applied algorithm is proposed..(4)It studies the target tracking, the hitting-point tracking is proposed .What's more, based on the comparison and analysis of the various algorithms of tracking andtarget prediction, a new Kalman filter algorithm is presented.
