摘　　要：针对以往文献在处理空间目标图像时使用的配准帧差方法,存在不能配准旋转背景以及没有充分利用目标运动特征等问题,提出了一种基于恒星配准的检测方法。该方法以恒星为控制点,利用刚体变换模型配准相邻帧,再通过帧差分离出可疑目标,最后通过最近邻航迹关联法确认真实目标,其中为了有效区分相邻帧中的目标点,对原始帧差法做了一些改进。最后利用增加了人工仿真点的实摄观测图像对算法进行实验,结果表明,该方法能较好地配准旋转背景序列图像,可以有效检测出空间点目标。Some literature used frame difference to detect space point targets, but their method could not register revolving background and ignore the characteristic of targets movement. We present an algorithmic based on registration of stars which used stars as control points, register neighbor frames by rigid model, separate doubtful targets by difference and affirm the real targets by track association. In order by distinguish points in different frames efficiently; we improve on the old difference method. We examine the algorithmic by real images which added manual points. Result show that the algorithmic can register the revolving background images and detect the space point targets.
