摘要:
Video Stabilization is one of the most important tasks in video surveillance on boarded of airship platforms. Facing the new problems that airship platforms usually have strong low-frequency vibration caused by wind and low-frequency wobble in video streams could not be effectively reduced by those method designed for casual handhold devices, a new video stabilization method for airship surveillance is proposed. In this method, camera path estimation is carried out by a modified method using GPS and attitude data of the key frames, and a new camera path planning method is given under 3 generalized conditions of airship's motion properties. Quantitative experimental results of some real airship video streams show that, our method can effectively reduce the low-frequency wobble and produce more stable video streams.
