3D infrared scene simulation technology plays an important role in the development and performance evaluation of military weapons.In the infrared simulation of ground objects,the infrared texture is an essential part of the data in the scene,and its reality determines the scene simulation fidelity to a large extent.Because the visible light remote sensing image has clearer details than the infrared remote sensing image,it can more accurately reflect scene distribution on the earth's surface.Therefore,in this paper based on visible images,the generation method of the infrared texture modulation template which could be helpful to improving the reality of the simulation scene was studied.In this paper,the problems and shortcomings existing in infrared texture in infrared scene simulation were discussed first,and then the traditional method of generating infrared texture modulation template based on visible remote sensing image was improved.The main works are as follows:(1)In view of that the existing remote sensing image resolution cannot satisfy the demand of infrared scene simulation,the ultra-resolution method of remote sensing image was studied,and the remote sensing image was reconstructed with super-resolution by using the self-similar information in remote sensing images.Because the reconstruction process was too time-consuming and inefficient,a block processing method with unified database based on parallel processing thoughts was adopted,reducing the operation time,and finally,an generation method of infrared texture modulation template with high efficiency and clear details was obtained.(2)In view of the phenomenon that the shadow fixation and its covering the ground objects information in remote sensing image,started with the shaded region characteristics,an automatic segmentation detection method based on texture was studied,and then the shadow area was compensated by analyzing the light model of the shaded area pixels,and a few small areas that were difficult to compensate were fixed based on the determination of pixel confidence level in the image,and thereby infrared texture modulation template that was not restricted by the shaded region generated.
