Research on Method for Generating Infrared Images of Aerial Target Based on Image Synthesis

摘要

A rapid method to generate infrared images based on image synthesis is proposed in this paper. At first, a three-dimension geometric model of the airplane is created by 3DMax software. Infrared radiance model of the airplane in accordance with infrared radiation theory is established, and the impact of atmospheric attenuation is considered, then the infrared images of airplane are generated. Finally, the synthesis of the generated images and actual shooting background images is achieved. To improve simulation reliability and fidelity, several aspects are thought in this paper for the synthesis, they are the atmospheric effect, the optical of imaging system effect, the random noise of detector, the synthesis revision of generated image and actual shooting background image. Experiment show that the simulation credibility is improved obviously, and the synthesis speed is advanced to 100 frames per second. The running environment is: PC, 512MB of RAM, 1.60GHz of CPU frequency. This method will be reference for testing and evaluating infrared search and track system.
