    • The present invention relates to the field of video surveillance. Disclosed are a method and device for extracting surveillance record videos. In the present invention, the method for extracting surveillance record videos comprises the following steps: acquiring and storing lens viewsheds of cameras and an irradiation time period corresponding to each lens viewshed; extracting lens viewsheds corresponding to irradiation time periods that have intersection relationships with a query time period; calculating intersection relationships between the extracted lens viewsheds and a target location; obtaining a set of cameras corresponding to lens viewsheds that have intersection relationships with the target location; and extracting videos captured by the cameras according to irradiation time periods of the cameras in the camera set. Cameras relevant to the target can be found through intersection calculation performed on a designated target location in a designated time period of the user and selected camera viewsheds, so as to directly extract from the relevant cameras videos meeting conditions and useful for the practical application, thereby reducing the labor and time consumed in manual checking of video records.
    • 本发明涉及视频监控领域。 公开了一种用于提取监控记录视频的方法和装置。 在本发明中,提取监视记录视频的方法包括以下步骤:获取和存储相机的镜头视图和对应于每个镜片的照射时间段; 提取与具有查询时间段的交集关系的照射时间段对应的镜头视图; 计算提取的透镜视角和目标位置之间的交点关系; 获得对应于与目标位置具有交集关系的透镜视角的一组相机; 以及根据照相机组中的照相机的照射时间段提取照相机拍摄的视频。 可以通过在用户的指定时间段内的指定目标位置和所选择的摄像机视角进行交叉点计算来找到与目标相关的相机,以便从相关摄像机直接提取视频会议条件并对实际应用有用,从而 减少手动检查视频记录所需的人力和时间。
