Problems solved by technology

This device has the following disadvantages: ①The acquisition device often has a fixed angle and position, and cannot give early warning of fires in blind spots and occluded areas of the video
② It is difficult to effectively judge the flames with small fire intensity and the blue flames burning some special substances or chemical materials
③Multiple acquisition devices are required to select a suitable area to fix, the layout method is complicated, and the number of devices is too large, resulting in difficult management and maintenance, and time-consuming server-side processing

Abstract

The invention discloses a fire early warning method and system. The fire early warning method includes: collecting video in a range greater than 180 degrees; using a dynamic capture method to process the video to obtain video frames in the dynamic area; using a convolutional neural network to classify the video frames in the dynamic area; using a neural network model to The classified flame video frames are analyzed for flame dynamic attributes to determine whether a fire has occurred. The fire early warning method and system disclosed in the present invention can monitor the area where the video acquisition device is located at a large angle, reduce video dead angles and occluded areas, quickly analyze the type of flame and the dynamic properties of the flame, and provide detailed information for extinguishing fires .

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a fire early warning method and system. Background technique [0002] At present, the traditional method for early warning of fires is to use ordinary network cameras to transmit video to the server, and the server intercepts frames, and uses algorithms such as "flame detection algorithm based on color space" and "dynamic layered characteristics of flames" to analyze the fire in the frame. The flame-like area is judged. For example, in video-based flame recognition, the BP algorithm is used to analyze the edge color distribution, flicker frequency, area change rate and other characteristics of the flame on the basis of color. This device has the following disadvantages: ① the acquisition device often has a fixed angle and position, and cannot give early warning of fires in blind spots and occluded areas of the video. ② It is difficult to effectively judge the flam...
