Abstract

This paper proposes a method of infrared moving target detection and its azimuth information display based on background difference. First of all, in view of the shortcomings of the current VIBE (Visual Background Extractor) algorithm, we propose a moving target detection algorithm based on the improved visual background extraction. This improved algorithm makes full use of the temporal and spatial domain information of the image, which can not only adapt to different detection environment, but also effectively eliminate ghosting to have better detection results for small targets. Then, we design an infrared video moving target detection system based on FPGA, including three modules, namely target detection module, GPS (Global Position System) information extraction module and character superimposing module. Furthermore, the system has the function of target extraction and azimuth information display. Compared to the traditional two-dimensional(2D) infrared moving target detection, this method superimposes GPS data onto 2D image information to facilitate real-time detection so that the moving state of the target can be understood more comprehensively, which has wide application value in the sea, land and air moving target detection and location.
