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 fr a me grabber to develop a real time image acquisition and processing the virtual instrument system. Drive general-purpose image acquisition card by calling the dynamic link library complete image acquisition, the acquisition of the image fr a me rate up to 25 per second. NI-IMAQ Vision video processing module, image processing, in order to complete the calibration of the photodetector. The system has the flexibility, high reliability, high cost.
