Video monitoring method and video monitoring device based on rear-end face recognition

The invention discloses a video monitoring method and a video monitoring device based on rear-end face recognition. According to the invention, a video stream of a monitoring video is read; the videostream is decoded into a plurality of decoded pictures; a first face picture containing a human face is extracted from the plurality of decoded pictures; a corresponding relation between each face andthe first face picture is determined; the first face picture is matched with a second face picture in a deploy and control base library, wherein the second face picture corresponding to a to-be-monitored face exists in the deploy and control base library; if the first face picture is matched with the corresponding second face picture, the prompting is carried out. According to the invention, theface recognition purpose is realized in real time no matter whether the face recognition function can be realized or not in the current scene. Therefore, the technical effects of real-time deploy andcontrol can be realized. The
