3D Scene Modeling of Goal and Research on Real-time Infrared Simulation

针对景象匹配系统对红外图像实时性的要求越来越高的特点,提出了基于目标三维场景的实时红外仿真方法。首先,设计了红外场景仿真的总体方案;其次,对材质红外图像计算、红外图像数据库建立、基于全球三维场景的实时红外场景建模三个关键技术做了初步实现;最后,结合红外场景仿真方案完成了系统。实验结果表明:该方法生成的红外图像与实拍红外图像的变化规律基本一致,从而为实时制备红外基准图提供了一种有效途径。

In this paper a real-time infrared simulation method based on the 3D scene modeling of goal is presented because of the more and more high real-time characteristic of infrared image requirement which is in the scene matching system.First of all,design the overall project of the infrared scene simulation;Secondly,implement three key techniques that the material of infrared image calculation,infrared image database established and real-time infrared scene modeling based on global 3D scene in preliminary;Finally,the system is developed by the overall project of the infrared scene simulation.It can be seen from the experiment results that regularity for change of the infrared image which is generated by this method and the infrared image which is generated by the real shooting is basically consistent,and provides a effective way for the preparation of real-time infrared benchmark figure.
