Multiband fusion detection method based on unmanned platform

Abstract

The invention discloses a multiband fusion detection method based on an unmanned platform. An infrared image sequence and a visible light image sequence obtained on the unmanned platform are subjected to spatial registration, then, the registered infrared image sequence and visible light image sequence can be preprocessed, the preprocessed infrared image sequence and visible light image sequence can be subjected to image fusion, and finally, the fused image sequence is subjected to dim small multi-target detection processing to output the state data and the number information of a target. An infrared and optical image fusion technology is adopted to realize the accurate detection of the target. The defects that the unmanned platform is poor in imaging quality and a single infrared detector is low in resolution and is not favorable for accurately identifying the target are solved. In addition, an algorithm is superior to a traditional target detection algorithm, can more easily detect and identify the target, can provide an accurate target instruction for a defensive system and a confrontation system, and can be widely applied to various types of complex-background accurate detection systems of dim small targets.

Description

technical field [0001] The invention belongs to the technical field of infrared and optical image processing and target fusion detection, and in particular relates to a multi-band fusion detection method based on an unmanned platform. Background technique [0002] Unmanned platform refers to a type of platform that is unmanned, operated completely by remote control or autonomously according to pre-programmed programs, and carries weapons to perform certain tasks. It includes unmanned combat aircraft, unmanned surface craft, unmanned submarine vehicles and Unmanned ground platforms and weapon systems including torpedoes, mobile mines, ballistic and cruise missiles. Because of its unique advantages such as low risk, low price, suitable for detecting targets under clouds or concealed, suitable for long-term "stalking" surveillance, detection, early warning, stable aiming, fire control and strike assessment, it has always attracted attention. At present, UAV imaging sensors can...

Problems solved by technology

Visible light imaging sensors use the principle of light reflection to capture images with clear details in color, but under conditions of low visibility, the obtained image effects are limited; infrared imaging sensors use the principle of thermal radiation, and the obtained images are infrared The target brightness is high, but the target is not clear and the edges are blurred
