基于Vega的红外星空目标视景仿真

Simulation of IR Image in Star Map Based on Vega

由于获取真实星空红外图像难度大、成本高、耗时长,提出了利用SensorVision模块进行星空目标红外视景仿真的方法;根据热平衡理论,从建立目标卫星的温度模型入手,利用Creator绘制空间目标模型,应用Vega、SensorVision模块生成星空背景下某卫星飞行的红外图像,实现了任意位置、任意视角的观测效果;为红外探测系统的构建提供了可靠的理论依据,也为航天工程中目标检测与跟踪的数据源实时仿真提供了可行性的参考方法。

Acquisition of real star infrared image is difficulty,which takes a long time and costs high.A method of simulation of infrared image based on celestial background using module of Vega SensorVision is proposed.the satellite infrared images are generated based on the theory of thermal balance,which start with the establishment of the target satellite＇s temperature model,mapping spatial object model with the software Creator,Vega and SensorVision modules in the star map.Space-objective dynamic scene is seen at any time,any angle and the size of field observations.The method provides a reliable theoretical basis for building infrared detection system,which also has provided a reference method for moving targets detection and tracking real time in aerospace engineering.
