Research On Infrared Scene Simulation Based On OSG

Infrared scene simulation significantly oriented the development of scene simulation.It can be used in military field,such as the guidance performance testing of infrared guided weapons.For the research of the infrared terminal guidance performance testing,the laboratory of author has set up a hardware-in-the-loop infrared simulation system.In this paper,the infrared scene simulation is studied to generate the dynamic infrared gray images,which provide the infrared radiation data for the simulation scene.In this paper,the scene of the attack on the ground tank targets by air to ground missile is simulated.And the infrared scene simulation is studied based on OSG.Compared with other scene simulation softwares,it has a good open source and has unique advantages in the field of global scene simulation,which has less restrictions on scene simulation.In this paper,at first,analyse the infrared radiation characteristics of the target and the background,and research the calculation method of the radiation data.Secondly,establish the target and background models,and build the three-dimensional scene of the air-to-ground missile.Thirdly,propose the infrared simulation method of the large-scale terrain background,do the infrared rendering of the target and the background based on the GLSL language,and display the infrared radiation data of the scene as an infrared grayscale image.Finally,the experimental scheme is designed to test the effectiveness and real-time performance of the infrared simulation.A large scale terrain background model is established.In order to solve the problem of infrared simulation,this paper proposed an infrared simulation method based on material and relative height for large-scale dynamic scheduling of terrain.
