The invention relates to the technical field of image processing, and in particular to a smoke detection method, which includes: using a dark channel prior method and a bilateral filtering method to enhance the collected video image; and obtaining the video image according to the enhanced video image and the atmospheric scattering model. Transmission function; use the ViBe method to detect the acquired transmission function to obtain the smoke candidate area; based on the ViBe method detection results, perform gradient reconstruction on the enhanced video image to restore the background area covered by the smoke candidate area; for each background area after gradient reconstruction pixel, find the similarity between the pixel and the corresponding pixel in the background area of the enhanced video image. When the similarity exceeds the preset similarity threshold, the pixel is determined to be a smoke pixel. The invention also relates to a smoke detection device. The smoke detection method and device provided by the present invention have fast detection and high accuracy, and can not only distinguish smoke from other moving targets, but also distinguish smoke from shadows.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a smoke detection method and device. Background technique [0002] Fire is one of the important reasons that threaten social development and personnel safety. The traditional method of fire detection is to distinguish the particles burned by fire. However, in places where the space is relatively open, the time for fire particles to reach the detection standard of the detector will be greatly increased, so it is difficult to achieve the purpose of fire warning. With the development of image-based pattern recognition and image processing. Fire detection based on video images has been a mainstream research direction. When a fire occurs, smoke is often produced first, so smoke detection based on video images is the main means of fire warning. At present, many smoke detection methods based on video images are usually unable to accurately detect the location of smoke, are ...
