Infrared scene simulation has extensive application value in military and civil fields. According to the specific experiment environment, this paper simulation of an infrared scene and according to the experimental data produced infrared texture library. First of all, through the 3Dmax modeling software to establish the target infrared radiation model, and calculate the relevant radiation data of it. Then analyze the radiation characteristics of the relevant materials, the establishment of infrared texture library for each material. And finally, use OGRE engine image rendering technology and GPU programmable pipeline technique to simulate a complex infrared scene close to the real.

Edge detection that is an important means to realize image segmentation has important application significance in image processing, industrial detection, artificial intelligence and the target recognition field. As the demand for real-time and rapidity in image processing, the embedded image processing technology has been widely applied. But the realization of real-time edge detection for image requires a large amount of data processing, limited system resources of embedded system is the main reason of the embedded image processing technology development. In order to shorten time embedded systems edge detection processing large amounts of data, based on adaptive threshold Canny algorithm, this paper as the FPGA data processing DSP chips and made a FPGA + DSP hardware architecture, effectively improve the system real-time, get a good edge detection results.

Infrared scene simulation is an important issue in the military field. Infrared scene simulation system can reproduce and simulate the infrared radiation characteristics of target and its background. Therefore, the analysis of the infrared radiation of target and scene features is very important for Infrared scene simulation. In this paper, we focus on the calculation and analysis of typical environmental factors of ground targets, including solar radiation, sky atmosphere radiation and ground radiation etc.. We also discuss how to calculate the infrared radiation of target in this paper. The results of this paper will be used for analysis of the infrared radiation and the simulation of the infrared scene of ground targets.

Infrared thermal imaging technology in various fields has been widely used. This paper firstly sets up the three-dimensional targets infrared radiation models and the atmospheric transmission model, and then generates the associated radiation data; Secondly building target 3D geometric model, the radiation data is mapped to the three-dimensional model, target in the 3D space is reconstructed of the infrared radiation characteristics; Finally it is using OGRE image engine rendering technology and GPU programmable pipeline technology that generate the target infrared image. This will have important significance to the next step to construct complex infrared scene.
