Abstract

The invention relates to a flame recognition algorithm based on image processing technology, belonging to the technical field of fire detection systems. Combustion of common substances usually produces flames, and the flames produced by fires have obvious image features, so flame recognition is used as a specific method of fire detection. The patent of the invention mainly finds the highest point and the center of gravity of the flame through the extraction algorithm of the inner and outer flames, and records the coordinates of the two points respectively; then makes a line connecting the two points and extracts the RGB value on the line connecting the two points; The RGB value on the line is compared with the standard flame RGB feature library, and a matching value is obtained by comparison, and then whether the image is a flame image is determined by the size of 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...
