摘　　要：针对空间环境中的监视高速运动小目标的需求,提出一种基于红外图像的空间目标探测方法,实现对空间非合作目标的检测、跟踪与识别。根据目标红外特性,目标检测过程采用阈值分割算法分割目标,通过重心法提取目标质心,采用星图匹配方法剔除恒星背景;目标跟踪识别过程采用轨迹关联算法进行多目标编批及轨迹跟踪,采用基于目标运动速度信息和方向矢量信息的目标分类算法最终识别目标。实验结果表明,应用该方法能够在1 s内实现空间目标探测,满足空间环境监视对目标探测的实时性好、检测概率高、虚警概率低等要求。For the needs of monitoring small high-speed moving object in space environment,a space target detection method based on infrared images was proposed to realize the detection,tracking and identification of non-cooperative space targets.According to the infrared characteristics of the target,the target detection progress adopted a threshold segmentation algorithm to segment the target.The center of mass of the target was extracted by the center of gravity method.The star background was eliminated by the use of the star pattern matching method.Target tracking and recognition process used trajectory correlation algorithm for multi-target batching and trajectory tracking.The target was ultimately identified using target classification algorithm based on the information of motion velocity and direction vector of the target.The experimental results show that with the proposed method,the tested space target can be detected within one second,meeting the requirements of good real-time detection,high detection probability,and low false alarm probability for space environment monitoring.
