Abstract

The embodiment of the invention discloses a method, equipment and a system for achieving video retrieval. The method comprises the steps that an alarm event is received, wherein the alarm event comprises equipment identification of alarm equipment and alarm occurrence time; a video index of a video corresponding to the alarm event is generated according to the alarm event, wherein the video index comprises video time information and video acquisition information; and a video bookmark of the video corresponding to the alarm event is generated according to the alarm event, wherein the video bookmark comprises camera identification and the alarm occurrence time. According to the method, the equipment and the system, when the alarm event is generated, the video bookmark and the video index of the video corresponding to the alarm event are generated according to the alarm event, and stored in an associated manner, so that a follow-up user can retrieve the video bookmark of the video corresponding to the alarm event, and acquire the relevant video according to the video acquisition information in the video index associated with the retrieved video bookmark conveniently, a monitoring worker can search the required monitoring video out of a great number of monitoring videos conveniently and quickly, the retrieval cost of the monitoring worker is lowered, and the working efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of network video monitoring services, and more specifically, relate to a method, device and system for realizing video retrieval. Background technique [0002] Network Video Surveillance (NVS, Network Video Surveillance System) service is a remote video surveillance service based on a broadband network. This service uses a broadband network to connect scattered and independent image collection points to the Internet to achieve unified monitoring, unified storage, and unified management across regions. ,Resource Sharing. [0003] In the field of video surveillance, the video surveillance system produces a large number of videos every day. When necessary, the surveillance personnel must retrieve valuable surveillance videos from the massive surveillance video files, which will take up a lot of working time of the surveillance personnel. Moreover, since most surveillance video images have a low rat...
