新兴数字视频稳像中相机运动估计技术综述

摘要

To find out the present situation,problems and future development of camera motion estimation (CME) in digital video stabilization (DVS),this paper made a careful study of it.This paper surveyed and analyzed current related articles,and divided CME in the emerging DVS into 3D method,sensor-based method and emerging 2D method.For each method,this paper discussed its research status,achievements,inefficiencies and challenges.Considering both the technology and market factors,this paper prospected its future development.The result of the research shows that the CME techniques in DVS are still needed to be improved both in real-time application and in estimation accuracy.%为了解当前数字视频稳像中相机运动估计技术的发展现状、存在问题和发展前景,对其进行了研究.通过对相关文献的归纳和分析,将新兴数字视频稳像中相机运动估计技术分为3D运动估计、传感器辅助运动估计以及新兴2D运动估计,并分别讨论了各种运动估计技术的研究现状、研究成果、不足和挑战;最后,结合技术和市场因素对数字视频稳像中相机运动估计技术的发展前景进行了展望.研究表明,当前数字视频稳像中相机运动估计技术在实时应用和估计精度上都有待改善.
