摘　　要：提出了一种高速高精度实时红外视频处理及采集系统设计,采用高速DSP芯片对红外视频图像进行非均匀校正,配以传输速度高达480Mb/s的USB2.0接口芯片实现与主机接口,视频图像的显示及后续处理由计算机完成。实验验证了该系统具有高速、高精度、实时性强等特点,适用于高精度的红外视频采集和辐射特性测量。A high-speed, high-precision and real-time Infrared video processing and acquisition system is presented. The Infrared video image nonuniformity correction was implemented by high speed DSP, and the USB2.0 interface chip, whose transport speed is as high as 480Mb/s, was used as the interface between the system and PC, finally, the video image display and post-processing are fulfilled in PC. The experimental results validate that the system has the characteristics of high speed, high precision, etc, and the system is a useful forrealizing infrared video acquisition and infrared parameters measurement.
