摘　　要：动态红外图像实时生成是红外成像半实物仿真系统的关键技术。介绍了国内外在该领域的研究现状和发展趋势,研究了空中目标的红外辐射模型和基于计算机图像生成技术进行红外图像生成的过程,分析了Vega生成红外图像的原理,并提出了采用商用图形工作站组建图像生成系统的方案。采用HP图形工作站组建硬件平台,在VC环境下采用Vega红外模块编写图像生成软件,在三种不同工作方式下对实时性进行了定量的测试。结果表明:PC架构商用图形工作站的计算能力能够满足红外成像半实物仿真对成像实时性的要求,配以像素数据协处理板卡,该方案还可以满足未来更大图像规模的应用需求。Dynamic infrared image generation is the key technology of the infrared imaging HWIL system. Domestic and foreign study on this field and the development trend is present. The infrared model of air targets and the infrared image generating procedure based on CIG are studied. The infrared image generation theory of Vega is analyzed. A more cost-effective image generation solution using commercial Image Workstation is introduced. The hardware platform is built with HP workstation and the software is written with Vega under VC development environment. The real-time quality is measured under three different conditions. The results indicate that the solution＇s calculation capacity can meet the infrared imaging HWIL system＇s real-time demand. If equipped with pixels coprocessor card, the solution can also meet the future demand of even large image size.
