红外小目标实时检测系统实现

采用TI的C6416为核心处理器,辅以FPGA,构建了一套红外小目标实时检测系统,主要算法由两片C6416并行处理实现,FPGA完成图像预处理和对外接口.算法上提出了基于双滑窗的局部阈值二值化方法,并采用图像预处理技术来改善图像分割效果,利用目标在连续帧间运动的关联性来剔除干扰目标、降低虚警概率.实验表明,系统的目标检测效果和实时性均达到了要求.

Implementation of Real Time Infrared Small Target Detection System

An infrared small target detection system is designed,using C6416 DSP as core processor,and FPGA as coprocessor.Main algorithms is realized on two parallel C6416,and image preprocessing on FPGA.Local threshold binarizing method based on two-sliding-window is adopted,and image preprocessing technology is used to improve segmentation effect.Jamming target is removed using frame coherence of the moving target.Experimentation has shown that,the system has good target detection effect and real-time performance.
