本文在LabVIEW和NI-IMAQ Vision软件平台下，利用通用图像采集卡开发一种图像实时采集处理虚拟仪器系统。通过调用动态链接库驱动通用图像采集卡完成图像采集，采集图像的帧速率达到25帧每秒。利用NI-IMAQ Vision视频处理模块，进行图像处理，以完成光电探测器的标定。该系统具有灵活性强、可靠性高、性价比高等优点。-In LabVIEW and NI-IMAQ Vision software platform, the use of a common frame grabber t

VC++动态链接库编程之DLL*（简单篇） DLL在程序编制中可作出巨大贡献，它提供了具共性代码的复用能力。但是，正如一门高深的武学，若被掌握在正义之侠的手上，便可助其仗义江湖；但若被掌握在邪恶之徒的手上，则必然在江湖上掀起腥风血雨。-A dynamic link library programming of the VC++ the DLL Trojans (simple articles) DLL programming make a significant contribution,
