A weak and small heat source target detection method in space background

Abstract

The present application provides a kind of weak small heat source target detection method in space background, comprising: obtaining several space background infrared images with real heat source label, input into the weak small heat source target detection network model constructed, obtain the heat source detection result in the space background infrared image, the weak small heat source target detection network model includes image enhancement unit, encoder, feature fusion unit, decoder;Based on the heat source detection result and real heat source label, establish total loss function, optimize the weak small heat source target detection network model constructed, when total loss function value reaches minimum, obtain the weak small heat source target detection network model trained;The space background infrared image to be detected is input into the weak small heat source target detection network model trained, and the heat source detection result in the space background infrared image to be detected is obtained.The present application can improve the detection precision of weak small heat source target in space background, avoid false detection and miss detection.
