摘　　要：为克服无人机侦察视频索引人工标注的主观性强和基于内容的方法运算量大的问题,鉴于飞行过程与侦察视频之间的参数对应关系,提出一种基于飞行参数自动标注的方法。这种侦察视频索引自动标注方法是在无人机遂行侦察任务的过程中,采用飞行参数组成的一个四元组对侦察视频镜头进行分割,进而可以运用首尾帧提取法得到关键帧。该方法有效利用了飞行过程的先验信息,完全独立于侦察视频完成了其结构化分析,由此可以高效地建立索引数据库。In order to overcome the strong subjectivity in manual marking the reconnaissance video indices of UAV and the huge operation of content-based indexing algorithm,an aviation parameters-based automatic marking method is proposed according to the corresponding relationship between the parameters of flying process and reconnaissance video.With this automatic marking method for reconnaissance video indices,during the reconnaissance flying of UAV,the scene of the video shot is segmented with a quadruple formed by some aviation parameters,and then the key-frames can be picked up using the first-and-last frame extraction.In this method,priori information of the flying process is effectually utilised and the structuralised analysis is accomplished entirely independent to the reconnaissance video,in this way the indexing database can be established efficiently.
