Summary:The invention relates to a video stability augmentation method and system for visual monitoring of a flapping-wing flying robot. The method comprises the following steps: generating feature points and feature point tracks of a visual image; performing periodic segmentation on the feature point trajectory, obtaining a video frame rate, and calculating to obtain an instantaneous frequency of the feature point trajectory; adjusting the time interval of the feature points according to the instantaneous frequency, and then carrying out linear sampling to generate an original track; interpolating the original trajectory to obtain an interpolated trajectory; averaging the interpolation trajectory to obtain a smooth trajectory; adjusting the time interval of the smooth trajectory, and performing linear sampling to obtain a final smooth trajectory; based on the original track and the final smooth track, frame-by-frame image correction is carried out, and a stabilized video is obtained. According to the method, each fe
