Research On Simulation And Generation Technology Of Infrared Image Based On Vega

the simulation generation technology of infrared scene by computer is one of the most important research directions in the field of visual simulation.It is widely used in military defense,aviation technology and civilian target tracking.It has strong practical significance.In this paper,the aircraft is selected as the target of infrared simulation,and the simulation of infrared image is realized by digital simulation technology.We use 3D modeling software Creator to build a three-dimensional geometric model of flight target through lofting technology and texture mapping technology.For infrared simulation of the target,the TMM texture mapping tool is used in combination with the image processing technology to complete the spontaneous radiation effect simulation of the target.Then the atmospheric radiation model is established with the MAT atmospheric generation tool.Then,the simulated image of the infrared target in the form of gray scale is obtained through the radiation mapping algorithm at the bottom of the Sensor of Vega.For infrared simulation of the background,Based on the method of region of interest segmentation,the background image with visible light texture is cropped and segmented,and then relevant materials with thermal radiation property are added on it.Then,according to the mapping relationship between radiation brightness and grayscale value,the infrared background image is obtained by using Vega infrared simulation module.Will finally get to target simulation of infrared image simulation and background infrared image using OpenGL and Vega mixed programming to realize the synthesis.Through the API function interface of Vega software,the secondary development of mfc-based simulation program was realized on VC++6.0 platform,and an infrared visual simulation software platform was built for user interaction.The software is designed with object,background,infrared detector and other parameter modules,which can not only show the flight perspective of the target in multiple directions,but also realize the functions of location,tracking and real-time preservation of infrared images and other functions.At the end of the paper,the simulated infrared image and real infrared image are compared and evaluated by using one-dimensional,two-dimensional histogram analysis method and comprehensive evaluation index.
