| 摘 要： | 介绍了一种用于红外焦平面成像仪参数客观测量的红外准静态图像采集和处理平台的设计与实现。该平台可从动态视频流中以任意格式抽取出任意一帧的数据，用CPLD和DSP自动对其进行处理及分析，并把图像数据通过USB2．0高速总线传回PC，进行保存、显示及检验平台处理的结果。该平台再配合外围探测器和其它器件可方便地对红外热像仪各项参数（NETD、MRTD、MTF）进行客观测量。

| Abstract: | The design and implementation of the infrared quasi-dynamic image acquisition and processing platform are Introduced. Using this platform ,we can acquire frame data from the video stream, process and analyze the data with CPLD and DSP, and send the image data to PC by the USB2.0 high-speed bus for data saving,image showing and result checking. With the help of IR collimator, blackbody and temperature controller, we can process the objective measuring of many important characteristics of thermograph, such as NETD, MRTD and MTF. |
