| 摘 要： | 针对卫星拍摄的以深空为背景的视频图像中空间运动目标的检测问题进行了研究,提出了一种基于运动信息的目标检测算法。首先,通过均值滤波对图像进行降噪处理；然后,采用基于局部统计的可变阈值来分割单帧图像,使用灰度重心法计算像点坐标。当卫星凝视目标区域时,恒星可以认为是静止的,而目标依旧在运动,基于此,可检测出空间运动目标。基于某型卫星在轨拍摄的视频图像验证了算法的有效性。

| Abstract: | A space target detection algorithm in video with star image background from video satellite was researched,which was based on motion information. Firstly, average filter was used to decrease noise. Then a single frame image wassegmented using variable thresholding based on local image properties. When video satellite was staring interested area,stars in FOV could thought static and the target was moving. So space target could detected by motion information. Experi.mental results about video from satelllite demonstrated the effectiveness of the algorithm. |
