通过对WFS嵌入式视频监控系统H.264编码的数据分析,实现了在WFS非通用型文件系统中按录制时间对视频监控数据进行碎片级的搜索技术。同时并通过分析WFS非通用型视频监控文件存储规律实现了对该类型视频监控文件在格式化或删除的情况下的数据恢复工作。
Through the data analysis of H.264 encoding in WFS embedded video surveillance system, it implements the fragment-level search technology of video surveillance data by recording time in WFS non-universal file system. At the same time, by analyzing the WFS non-universal video surveillance file storage rules to achieve the type of video surveillance files in format or delete data recovery work.
