Personnel on-duty video recognition method and intelligent user information transmission device

Abstract

The invention discloses a personnel on-duty video recognition method and an intelligent user information transmission device. The method comprises the following steps of: firstly intercepting a video stream and obtaining an image frame sequence; modeling a background and extracting a differential region; and forming a human body target movement region by a group of image rectangular frames, assuming that a rectangular surrounding frame set extraction from an image movement area as M, carrying out an overlapping ratios between a rectangular surrounding frame Mi and the rectangular frames in the movement region Ri, obtaining a final identification region rectangular frame set S through one-by-one calculation, zooming each to-be-identified region rectangular frame Si in the set S, carrying out region-by-region identification on the to-be-identified regions by adoption of an on-duty identification algorithm, and judging whether persons exist in each region or not. According to the method, a personnel on-duty video identification system interface is provided, so that the on-duty conditions of firefighting operators on duty can be identified through a video analysis algorithm; and a remote configuration interface is provided, so that the remote software updating and setting configuration can be realized through a net-connected firefighting monitoring center.

Description

technical field [0001] The invention relates to a technology of urban remote fire monitoring equipment, in particular to a video recognition method for on-duty personnel and an intelligent user information transmission device. Background technique [0002] With the rapid development of social economy and the continuous advancement of urbanization, the degree of population concentration is getting higher and higher, the scale of enterprises is getting bigger and bigger, there are more and more high-rise and large buildings, and the hidden dangers of urban fire are also increasing. The occurrence of fire will bring In the face of huge casualties and economic losses, fire safety work is becoming increasingly important. At present, many buildings have installed automatic fire alarm systems, which can achieve fire warning to a certain extent. However, due to the negligence of personnel and the failure of alarm equipment, the phenomenon of false alarms and omissions occurs from t...
