Study on useful video recognition video tape recorder

Abstract

Generally, an existing video surveillance system directly stores real-time information which is monitored through a surveillance camera into a video tape recorder, not only is a video playback period prolonged, but also a large amount of storage space is occupied. According to a studied useful video recognition video tape recorder, an intelligent video surveillance analysis technique is utilized to achieve a goal of automatically starting a video tape recording function only when target video information is collected, an alarm system is simultaneously triggered when the video tape recording function is automatically started according to a set work recognition mode, and disadvantages of a traditional video tape recorder are thoroughly overcome. Meanwhile, the useful video recognition video tape recorder further achieves that useful information can be automatically identified and classified, packed and stored again after the classification and can be simultaneously and piecewise played when replayed, corresponding display frames can be activated and segmented according the number of the segments, a large amount of space is saved for the storage of video information, time for retrieval, playback and query of the useful video information is reduced, and therefore precious time is saved for seizing opportunity to detect a case.

Description

technical field [0001] The invention belongs to the research field of useful video recognition video recorders, and aims to extract useful videos through in-depth analysis of camera video information, store only useful videos in video recorders, and realize automatic alarm according to a set mode. This device solves the problem of waste of video recorder space resources by useless video information, and at the same time greatly shortens the time required for playback of recorded video information, which has great practical significance for the prevention and timely detection of cases. Background technique [0002] With the continuous development of modern information society, people's demand for security is increasing, which makes the application of video surveillance system in the field of security prevention more and more extensive. The currently used video surveillance system usually directly stores the information monitored by the camera to the video recorder, and with t...
