Abstract:

A fast registration method for unmanned aerial vehicle (UAV) video frames was proposed in the paper, according to the need of rapid acquisition and processing of UAV video data in maritime surveys. Firstly,the time synchronization between the video frames and UAV positions and attitude information was realized using the method of time index and linear/spherical interpolation. Then the rough registration of video frames was obtained after geocoding video frames with digital differential rectification algorithm. Finally, the precise registration was obtained by controlling the zoom factor in affine transformation model to adjust geographic coordinates of the processed frames. The results show that this method is qualified for obtaining precise registration of video frames within route.
