介绍了超光谱探测设备的基本原理、系统的软硬件组成, 采用 Matrox公司的 MorphisQXT视频采集卡进行超光谱成像数据的信息处理, 详细介绍了 MIL Ltie 8.0程序库的体系结构, 对应的配置函数功能。结合 VC++6.0开发环境, 采用异步双缓存伪实时处理的方法, 实现图像动态采集, 并对采集的图像进行叠加, 添加伪彩, 直观体现超光谱探测设备分辨真假目标的功能。运行结果表明: MorphisQXT视频采集卡可以满足数据量大, 实时性高的要求。

The basic principle, hardware and software structure of the super spectral imaging detecting equipment are introduced. MorphisQXT video grabbing card from Matrox Co. is used to process super spectral imaging data. The system structure and corresponding functions of MIL Lite 8.0 program library are introduced in detail. Under VC++6.0 exploitation environment, fake real time process method of asynchronism double buffer storage is adopted. So image dynamic collection is realized. The images are spliced and added colors. And the function of distinguishing real targets from false targets of super spectral detecting equipment is implemented directly. The experimental results show that MorphisQXT video grabbing card has the ability of collecting large numbers of data in real time.
