Abstract
Video image plays an important role in people's life as an important information media. It is inevitable to be bumpy in the process of vehicle movement, at this time; the video acquired from vehicle traveling data recorder video will have the phenomenon of random jitter. In order to improving the effect of digital image stabilization, the purpose of this paper is to research the method of digital image stability of airborne video. This paper introduces the method and the composition of DIS, the basic principle and method of motion compensation. This paper has a further study of gray projection algorithm, and has made improvement at one point about traditional gray projection algorithm: enhancing grayscale contrast through image preprocessing, this solved the problem of gray-level changed not obvious. This paper had also proved these improvements are effective by experimental simulation.
