摘　　要：研究了红外成像仿真中目标与背景红外图像合成的重要技术问题,详细阐述了外部渲染方法的设计思想,并介绍了几种典型情况下通过外部渲染方法建立红外场景仿真时对目标进行分割和聚合的方式。此外,文中还给出了外部渲染方法的图像合成处理算法。最后通过一个仿真实例对该渲染方法进行了验证。通过对待渲染场景的目标进行合理的分割和聚合,该渲染方法可以有效地简化红外场景的建模处理,创建和合成出足够逼真度的红外场景。This paper explores the key issues about the synthesis of infrared images of targets and backgrounds, and it expatiates on design of the external rendering. In addition, various approaches of segmentation and aggregation of scene objects in several classical cases are introduced. Moreover, this paper presents an algorithm of imaging synthesis process in the external rendering. Finally, the external rendering is verified by using a simulation demonstration. By judicious segmentation and aggregation of scene objects, the external rendering can effectively simplify the scene modeling process, and create and compose infrared scenes that have sufficient EO signature fidelity.
