摘　　要：针对传统的红外运动图像序列中微弱点目标动态检测系统,普遍存在着检测率较低,检测效果较差等问题。设计一种新的红外运动图像序列中微弱点目标动态检测系统。该系统主要分为硬件和软件两个部分,硬件部分详细分析了检测系统中FPGA模块、DSP模块、扩展存储模块和图像输出模块的工作原理和流程;软件部分先利用单帧检测来初步检测出红外运动图像序列中的可疑的微弱点,再采用能量累积关联方法对可疑的微弱点进行第二次检测。测试结果表明,所提检测系统检测率较高,并且对图像中微弱点目标检测的效果较好。Aiming at the weak dynamic point target dynamic detection system in traditional infrared moving image sequence,there are common problems such as low detection rate and poor detection effect.A new dynamic detection system for weak point targets in infrared image sequence is designed.The system is mainly divided into two parts:hardware and software.The hardware part analyzes the working principle and process of FPGA module,DSP module,extended storage module and image output module in detection system in detail.In the software part,the suspicious weak points in infrared moving image sequence are detected by single frame detection,and then be detected by energy accumulation correlation method for the second time.The test results show that the detection rate of the proposed detection system is high,and the detection effect of weak point targets in the image is better.
