An Infrared Digital Scene Generation Technology

在基于数字微镜器件(Digital Micromirror Device,DMD)的红外景象仿真系统中,需要提供红外场景数字信号作为用于调制和控制DMD的输入源。为满足此项需求,提出了一种通用的红外数字场景生成方法。首先介绍了利用计算机生成基于Vega的红外模拟场景的流程,然后详细论述了开发红外场景驱动控制程序与格式转换程序的设计过程。该方法不仅可以将Vega红外场景转换为静态BMP格式图像和动态AVI格式视频等数字信号,而且还可以提高红外仿真场景应用的重用性和可移植性,因此具有很大的工程实用价值。

In an infrared scene simulation system based on a Digital Micromirror Device （DMD）, digital infrared scene signals are required to be used as the input source for modulating and controlling the DMD. To meet this requirement, a general digital infrared scene generation method is proposed. Firstly, the process of infrared scene simulation based on Vega by a computer is presented. Then, the design process of developing an infrared scene driving program and a scene format conversion program is described in detail. The method not only can convert the Vega infrared scenes into the static infrared images in BMP format and the dynamic infrared video in AVI format, but also can improve the reuse and portability of infrared scenes. Therefore, it is of great practical value to engineering applications.
