深空背景弱小运动目标检测算法研究

在深入分析监测设备CCD图像特点的基础上,提出了一种深空背景弱小运动目标检测新方法。该算法使用"列高通滤波器"进行背景抑制;采用序列图像多帧累加增强目标与恒星的对比度,用交叉投影法确定星点区域,提取局部星图,利用局部星图匹配剔除恒星干扰;结合候选目标的特征,采用基于逻辑的最近邻关联方法完成目标检测。结果表明,该算法可满足深空背景弱小运动目标实时检测的要求。

Research on dim moving target detection algorithm in deep space

After the image characteristic of the surveillance equipment is analyzed,a real-time dim moving target detection algorithm in deep space is brought forward.The algorithm utilizes row high pass filter to suppress background.The algorithm uses multi-frame addition to improve contrast between stars and targets firstly,it uses cross projection to confirm the star's position secondly,it uses the star-point matching to eliminate most disturbances of stars thirdly,data association based on logic principle and the ...
