An optical smoke detection method under sea and sky background

Abstract

The present invention relates to a method for optical smoke detection under a sea-sky background, comprising: for a target image containing optical smoke interference under a sea-sky background, segmenting smoke candidate areas based on smoke grayscale features; performing morphological processing on the smoke candidate areas, and confirming the smoke candidate areas by combining smoke shape information and smoke height information; performing edge extraction and fusion on the confirmed smoke candidate areas to obtain position information of the smoke areas, thereby obtaining the final smoke detection result output. The present invention achieves smoke detection without using motion features, solving the technical problem that the image background information constantly changes due to the continuous movement of the aircraft platform, making it impossible to use motion features to complete smoke detection. The algorithm has low complexity, occupies few hardware resources, can quickly achieve smoke detection, and is suitable for computing platforms with limited hardware resources.
