Abstract
A real-time infrared mixed targets detection system is designed to detect targets of uncertain number or sizes in a sky background during the real project. The system takes Digital Signal Processor (DSP) as its main processor and takes Field Programmable Gate Array (FPGA) as a preprocessor. As to the problem of mixed targets of different sizes, the method adopts degrading resolution of image to reduce the range of target size. To suppress the background and enhance the SNR of image, weighted mean-value filtering operations are used. To segment the image, a self-adaptive threshold segmentation approach is adopted. Finally, based on motion trajectory consistency, false targets are eliminated and real small targets are reserved through improved pipeline filter. The experimental results indicate that the method can satisfy the real- time requirement of infrared target detection system.
