Abstract

The invention puts forward a ship target detection method based on an infrared remote sensing image. The method comprises the following steps that: S1: carrying out water-coast separation on an infrared remote sensing image, and segmenting a sea area image which contains a ship target; S2: carrying out contrast enhancement processing on the sea area image obtained after the water-coast separation is carried out, highlighting the ship target in the image, and selecting the candidate area of the ship target according to the highlighted ship target; and S3: determining a ship suspected target in the candidate area, and extracting the ship target according to the personalized features of the ship. Under a situation of complex background interference including wind waves, cloud backgrounds, ship tracks, solar flares, islands and the like, the ship target can be accurately detected in real time.

Description

technical field [0001] The invention relates to target detection and recognition technology in the field of infrared remote sensing images, in particular to a ship target detection method based on infrared remote sensing images. Background technique [0002] Although the research on ship target detection and recognition technology based on infrared remote sensing images started relatively late, with the continuous improvement of payload resolution, high-resolution infrared images have shown outstanding advantages and broad prospects in ship recognition. At present, ship target detection based on infrared remote sensing images in a complex background is still a difficult point; on the one hand, due to the large ocean area, the ship information on the sea is very rich, resulting in a very large amount of data. Tail detection methods and detection methods based on C-V threshold segmentation are very time-consuming and not conducive to real-time processing; on the other hand, du...
