An Infrared Radiation Simulation Method for Aircraft Target and Typical Ground Objects Based on RadThermIR and OpenGL

The aircraft target in the airport and its ground background are significant in military applications. In order to employthe algorithms for the detection, identification and dynamic monitoring, a software which can complete infrared radiation simulation of aircraft/ground object in airports under conditions of different seasons, different meteorological conditions, different periods and different detecting bands is needed to provide training samples. This paper utilizes OpenGL to construct a model of the aircraft target in the airport and the ground object in Visual Studio2010. Combined withthe theoryof heat transfer and infrared radiation, this study embeds the RadThermIR software used for thermal infrared analysis and proposes infrared image simulation. Then we calculate the infrared radiation field model of the aircraft and its ground object. Choosingimage gray similarity as the evaluation metric, the infrared image simulation precision of this method is over 80%. Experiment results indicate thatour proposed method can provide training samples with analysis data of rich infrared characteristics and featured knowledge for the automatic detection and identification of aircraft targets in the all-weather airport.
