Weak and small target detection method based on satellite-borne infrared remote sensing image

Abstract

The invention discloses a weak and small target detection method based on a satellite-borne infrared remote sensing image. The weak and small target detection method comprises five steps of acquiring sample data, constructing a data set, amplifying the data set, roughly detecting a target and finely detecting the target. According to the method, an area where a weak and small target is located is preliminarily judged by using a shallow coarse detection neural network and then the target position is accurately positioned by using a deep fine detection neural network in a detection mode of combining coarse detection and fine detection, so that the detection efficiency is improved, the weak and small target can be rapidly and accurately detected under a complex sea and land background in an infrared remote sensing image, and the problems that an existing infrared remote sensing image target detection algorithm is low in target positioning speed, low in detection efficiency and the like are solved.

Description

technical field [0001] The invention relates to the technical field of remote sensing image target detection, and more specifically relates to a method for detecting weak and small targets based on spaceborne infrared remote sensing images. Background technique [0002] At present, as countries pay more and more attention to marine resources, the monitoring and tracking of important targets on the sea surface has become a research hotspot in recent years. Unlike SAR (Synthetic Aperture Radar, Synthetic Aperture Radar) and visible light remote sensing, infrared remote sensing can work around the clock without being affected by light, and has a long range of action, making it difficult to be discovered by the enemy. Based on this, the detection of weak and small targets based on infrared remote sensing images plays an important role in the field of military and civilian marine target reconnaissance.
