Abstract

The invention relates to a flame identifying algorithm based on image processing technologies and belongs to the technical field of fire detecting systems. Flames usually occur during combustion of common substances, the flames that cause fire disasters have obvious image features, and thereby, flame identifying is used as a specific method for fire detection. According to the flame identifying algorithm based on the image processing technologies, a highest point and a gravity center of the flames are found out through inner and outer flame extraction algorithms, coordinates of the highest point and the gravity center are recorded respectively, then a connecting line of the highest point and the gravity center is drawn through the coordinates, a red-green-blue (RGB) value on the connecting line of the two points is extracted, meanwhile, the RGB value on the connecting line of the two points is compared with a standard flame RGB feature library, a matching value is obtained through comparison, and whether the image is a flame image or not is determined according to the matching value.

Description

technical field [0001] The invention relates to a flame recognition algorithm based on image processing technology, mainly an extraction algorithm for internal and external flames of a flame and a flame discrimination algorithm. Background technique [0002] At present, in the field of fire detection, the main applications are gas-type, smoke-type, temperature-type, photosensitive-type and image-type fire alarm systems. The functions of the system include detection of fire, and then direct power-off, water spraying and other fire-extinguishing measures and alarm. However, for large space environments (such as oil depots, super large warehouses, oil terminals, etc.), there are many factors that affect fire detection in nature, such as space height, heat barrier, coverage, remote signal transmission, etc. Under these circumstances, traditional contact detection methods, such as temperature and smoke fire detectors, cannot be effectively used. Not only do they require high-cos...
