Abstract
The small unmanned Aerial Vehicles (UAVs) are more popular because of their lower flight height, shorter flight period and continuous affordability. However, the small UAVs are sensitive to wind and airstream during the flight. The videos are often characterized by jitter, so the effective image electronic stabilization is important. In this paper, firstly, the flight characteristics of small UAVs were summarized and analyzed. Secondly, we analyzed the following problems: 1) under condition of drifts, the intentional motion estimation is not easy and much information will lost if motion compensation is not conducted properly; 2) on the situation of large tilt angle, the motions of images are complicate, simple motion models are not suitable. In order to cope with these problems, corresponding algorithms were proposed. Finally, we conducted some experiments; the results indicated that our methods were effective.
