Research On Algorithms Of Infrared Ground Moving Target Tracking

The detection and tracking of infrared moving targets is widely used in many fields, such as military, surveillance system and so on. As the complexity of the ground background and the uncertainty of interference, it makes tracking of ground infrared target become the focus of scholars at home and abroad. The thesis studied the tracking of complex ground infrared target. The main achievement of this dissertation is as follows:First of all, we introduce the compositional structure of our infrared ground moving target tracking system,the characteristics of ground infrared image are deeply analyzed and studied, an algorithm of suppress noise method is researched and implemented. As the lack of target prior information, an adaptive template selecting method based on mixture ratio and Otsu threshold is proposed.Secondly, In the tracking stage,a moving target tracking method based on feature association and template matching is adopted. We select the corresponding tracking method according to the completeness of target information we get during the stage of adaptive template selection. When the target is isolated from the border, an tracking method based on adaptive weight multiple features fusion is presented. While the target is associated with the border, we improve the tracking method based on Kalman Filter and image matching. Additionally, we studied the tracking method for tracking target and similar objects, we use the tracking method based on Kalman Filter and image matching to track tracking target and similar objects.Thirdly, the updating method of template is studied..In order to reduce the drift of the matching template in the tracking process and make the matching template better adapt to the changes of the target, we use an adaptive template updating strategy to ensure the accuracy and stability.At last, we introduced the modules and state partition of Infrared ground moving target tracking system. Meanwhile, we will briefly introduce the system debugging software under the environment of PC and modification and optimization we make in the period of algorithm transplantation.
