双波段红外图像场景三维实时仿真平台设计

Simulation platform design of three-dimensional real-time dual band infrared image scene

当前红外场景三维仿真平台没有注重目标对环境辐射反射,降低了仿真的真实性。为此,设计了一种新的双波段红外图像场景三维实时仿真平台,首先对红外图像采集和处理进行分析,以获取模拟场景信号与真实图像之间的映射关系,然后选用"PC机+PCI插卡"系统结构对平台进行设计,,给出平台硬件总体结构,详细介绍了电源模块、接口模块、存储模块的设计,最后设计了双波段红外图像场景三维实时仿真平台的软件,实验结果表明,所设计平台精度高和实时性好。

At present,the 3D simulation platform of infrared scene does not pay attention to the radiation reflection of the target,which reduces the authenticity of the simulation. Therefore,the simulation platform design of a new 3D real-time dual band infrared image scene is proposed. Firstly the infrared image acquisition and processing were analyzed to obtain the mapping relations between the analog signal and the true scene image,and then choose ＂PC ＋PCI card＂system structure to design the platform,give out the overall structure of the hardware platform,and introduce the design of power module,interface module,memory module in details. Finally design the real time 3D simulation platform of dual band infrared images of the software. The experimental results show that the platform designed has high accuracy and good real-time performance.
