基于增强现实的动态红外场景仿真系统设计研究

传统的仿真技术会受算法的复杂度、运算能力及接口等的限制。针对这一问题，设计了一种基于增强现实的思想在真实图像上进行实时动态红外场景仿真的系统。首先使用3DS MAX生成虚拟目标模型，再对虚拟目标模型进行几何一致性变换和红外辐射一致性变换，使用SURF-ORB特征匹配对探测器的运动姿态进行跟踪，最终通过光栅渲染使虚拟目标与真实场景进行虚实融合，完成基于增强现实的动态红外场景仿真系统的设计。实验结果显示，该系统能够实现高帧频、高真实性的红外仿真图像，具有较强的可扩展性。

Design of Dynamic Infrared Scene Simulation System Based on Augmented Reality

Traditional simulation technologies are limited by algorithm complexity, computing power and interface bottlenecks. To solve this problem, a system which implements real-time dynamic infrared scene simulation in real images on the basis of augmented reality is designed. Firstly, 3DS MAX is used to establish a virtual target model. The geometric consistency transformation and infrared radiation consistency transformation are carried out for the virtual target model. Then, SURF-ORB feature matching is used to track the motion of the detector. Finally, the virtual target is fused with the real scene through raster rending. Thus, the design of the dynamic infrared scene simulation system based on augmented reality is completed. The experimental results show that high frame rate and high realism infrared simulation images can be obtained by this system. Its scalability is very strong.
