摘　　要：无人机视频帧具有低对比度和色彩可读性差等缺点,为了解决这些问题并从视频中自动获取视频帧,本文提出一种无人机视频帧自动拼接方法。首先介绍相位相关理论,并推导出指定重叠度视频帧提取公式,在此基础上进行指定重叠度视频帧的自动提取;最后利用改进的SURF算法完成视频帧的匹配和拼接。实验结果表明本文采用的方法能实现视频帧的自动提取和快速拼接。A method for automatic stitching of UAV video frames was proposed in this paper, in order to solve problems of auto- matic acquisition and low contrast and poor color readability. First, the designated overlapping degree of video frames was automatically extracted, based on the theory of phase correlation and the formula for automatic extraction. Then the overlapping area matching and stitching were done with the improved SURF feature matching algorithm. The experimental results showed that this method could realize automatic acquisition and rapid stitching of video frames.
