The invention discloses a
microsatellite non-cooperative target
image processing method. The
microsatellite non-cooperative target
image processing method comprises the steps that through calculation of the number N of pixels occupied by a target
satellite in a frame of initial image, whether the number N of the pixels is larger than a preset threshold value or nor is judged, if not, the feature of the target
satellite in the frame of initial image is identified based on the feedback
linear separation method, and if yes, the feature of the target
satellite in the frame of initial image is identified based on the feedback linear aggregation method. According to the
microsatellite non-cooperative target
image processing method, the feature of the target satellite can be directly extracted, additional arrangement and refitting do not need to be conducted on the target satellite, and no special requirement for the target satellite exists. Compared with a cooperative target image
processing method, a relevant
hardware structure for executing the microsatellite non-cooperative target image
processing method is low in
power consumption and light in weight. Compared with a method that for different relative distances of the target satellite, different
feather extraction algorithms are applied in a self-
adaptation mode and wide-range
feature extraction is achieved, the needed feature of the target satellite can be extracted as long as the target satellite has appropriate light.
