Embodiment Construction

[0030] In order to realize the intelligentization of fire monitoring, the present invention provides a flame video recognition method, a fire monitoring method and a system thereof. Next, the method and its system will be described in detail.

[0031] figure 1 A system structure diagram of the present invention is shown. Such as figure 1 As shown, the fire monitoring system of the present invention includes a camera 100 , a data processing board 102 , a network transmission unit 104 , a flame identification unit 106 and a fire alarm unit 108 .

[0032] The camera 100 acquires video images of the monitoring area.

[0033] The data processing board 102 establishes a background model based on the video image captured by the camera, and detects foreground objects in the video image.

[0034] The network transmission unit 104 transmits the image of the foreground object detected by the data processing board 102 to the flame recognition unit 106 .

[0035] The flame identificat...

Abstract

The invention discloses a method for identifying flame by video, a method for monitoring fire, and a system thereof. The method for monitoring fire comprises the following steps: acquiring video image, establishing a background model, and detecting prospect target in the video image; transmitting the image of the prospect target to a server end; judging which target points of the prospect target are color points of flame according to the color model of the flame established by training image; carrying out cluster analysis on the color points of the flame of the prospect target to acquire a flame area of the prospect target, and matching the prospect targets of the front and rear frame images; judging whether flame occurs in the flame area; when the matching relation exceeds the set threshold value; carrying out verification of a alarming verification mechanism when judging that flame occurs in the flame area; and when satisfying the warning condition, performing warning. The inventionhas wider range of application without limiting distance of scene, and achieves intelligentized processing.

Description

technical field [0001] The invention relates to a flame video recognition method, a fire monitoring method and a system thereof. Background technique [0002] With the development of social production, large-scale factory buildings, commercial venues, entertainment venues, and office venues all need to monitor the safety of the venues, especially fires, which bring huge losses. Therefore, it is of great significance to monitor fires in key fire prevention places or areas. [0003] Most of the existing fire alarm systems use point sampling sensors. These field-level proximity sensors and professional photoelectric equipment have different limitations in terms of operability, reliability, detection rate, site applicability, cost, and versatility. Especially for scenes with large areas and open areas, the sensors are far away from the scene, and the traditional fire alarm system is helpless. [0004] Some video-based fire alarm systems are nothing more than adding video tran...
