复杂背景下空中小目标动态红外成像仿真技术研究
Research on Dynamic Infrared Imaging Simulation of Small Aerial Target under Complex Background
摘要
Abstract
Infrared images of small aerial targets are widely used in the fields of target detection and recognition and military training,but the cost of obtaining these data is extremely high,and the data under some conditions are difficult to obtain,so it is of great significance to study the infrared image simulation technology of small aerial targets in complex backgrounds.A simulation method and software are established for infrared imaging of aerial target under complex background.An aerial target is modelled as a simplified 3D structure.The infrared radiation model of the target is composed by spontaneous radiation model and reflection model.The sky background is initiated freely,with consideration of camera perspective model and platform vibration.Target and background are fused through a Poisson model.The dynamic simulation of the flight trajectory of any number of flight targets is realized by setting the dynamic model of the target and the camera,which provides a way to efficiently simulate the infrared images of small aerial targets under different backgrounds and various flight conditions.关键词
