本发明涉及一种基于成像传感器视差的卫星姿态颤振探测方法,包括以下步骤:(1)获取视差影像,并对其进行预处理,视差影像包括相互间具有观测视差的参考影像和待匹配影像;(2)对视差影像进行精确密集匹配处理,获得两幅影像的视差偏差值;(3)根据视差偏差值计算卫星姿态颤振值。与现有技术相比,本发明可在不依赖地面控制点和附加硬件设备的基础上,对星体的姿态颤振进行探测和分析,得到真实的星体在垂轨和沿轨方向的姿态颤振值。
The present invention relates to a satellite attitude flutter detection method based on parallax of an imaging sensor, which comprises the following steps: (1) acquiring and preprocessing a parallax video which includes a reference image with observation parallax and a to-be-matched image ; (2) the parallax images are closely matched with each other to obtain the parallax deviation values of the two images; (3) the satellite attitude flutter values are calculated according to the parallax deviation values. Compared with the prior art, the invention can detect and analyze the attitude flutter of the celestial body without depending on the ground control point and the additional hardware equipment, and obtain the attitude flutter of the real celestial body in the vertical track and the track direction value.
