Abstract

The invention relates to the technical field of remote sensing image processing, in particular to a cirrus cloud false alarm source detection method based on multiband characteristics. The cirrus cloud false alarm source detection method comprises the following steps: inputting two cirrus cloud images of different bands and preprocessing the cirrus cloud images; solving the fractal dimension of apreprocessed image by using a covering method, and performing normalization processing to obtain a normalized fractal dimension feature map; enhancing the other preprocessed image by using a saliencymethod to obtain a saliency feature map; performing weighted fusion on the normalized fractal dimension feature map and the saliency feature map; and performing adaptive threshold segmentation on thefused image to obtain a detection result. The cirrus cloud false alarm source detection method method provided by the invention avoids the dependence of a machine learning method on a large amount ofsample data and the limitation of single-waveband image detection, can achieve the quick detection of a small sample, and remarkably improves the detection capability of a cirrus cloud false alarm source.

Description

technical field

[0001] The invention relates to the technical field of remote sensing image processing, in particular to a cirrus cloud false alarm source detection method based on multi-band characteristics, computer equipment and a computer-readable storage medium. Background technique

[0002] In recent years, remote sensing technology has been widely used in the fields of military, space-based detection and meteorological analysis. Among them, space infrared satellites are an important part of the earth observation and remote sensing system, and play an important role in early warning and missile interception. . For the space infrared satellite imaging system, there are a large number of false alarm sources with high radiation energy in its imaging band, mainly natural landscapes, such as high radiation terrain or phenomena such as snow mountains, frozen rivers, and high-altitude cirrus clouds. The images appear similar, with higher gray levels, which may cause false al...
