Abstract

The invention discloses a flame detection and positioning method based on multi-feature fusion and stereoscopic vision and relates to the field of computer vision. According to the method, an improvedVibe algorithm and an OHTA color splitting method are utilized to extract a suspected flame region; shape features, morphological overlapping degree features and area change rate features of a targetin the suspected flame region are extracted, so that a multi-feature fusion model is established to obtain the probability of flame existence, and whether a flame exists is detected according to theprobability; and finally flame positioning is performed according to the flame detection result, an SSDA stereoscopic matching algorithm and the principle of a parallel binocular stereoscopic vision system. The method has high anti-interference, robustness and instantaneity, the flame detection and positioning result is beneficial for positioning and extinguishment, and fire loss is lowered to themaximum extent.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a flame detection and positioning method based on multi-feature fusion and stereo vision. Background technique [0002] In order to meet the needs of the continuous improvement of people's living standards, there are more and more large public buildings that use large spatial patterns to highlight the architecture and scale. Buildings with an inner net height greater than 8 meters, such as gymnasiums, airport terminals, convention centers, large song and dance theaters, etc., are some representative large-space buildings. For these large-space buildings, ordinary smoke and temperature-sensing fire detection and alarm systems cannot quickly collect information on changes in smoke temperature from fires, while image-based fire detection technology has the characteristics of non-contact detection for fire detection, and is not affected by space height, heat, etc. barrier, explosive, ...
