摘要:
Video stabilization has been gaining in importance in earth observation and video surveillance on boarded of airship platforms. As the airship platforms have obvious low-frequency vibration caused by wind and the unstable attitude may also lead to geometric distortion in the video streams, and most of the traditional methods are designed for casual handheld devices which cannot effectively handle those kinds of problems, a new video stabilization method for airship earth observation is proposed. In this method, a modified camera path planning method based on piecewise linear L1 optimization is given under the specific motion properties of airship platform and the needs of geometric correction for each frame, and the camera path reconstruction is carried out with vision based motion estimation and sparse GPS and attitude data. The effectiveness of our method is confirmed by quantitative experiments over a variety of video streams. © Springer International Publishing Switzerland 2015.
