摘　　要：当前各行业的各种类型的监控摄像头的安装越来越普及,在交通测流、检测车辆违章、银行安保、工厂运行监控、产品加工等各方面都需要进行实时监控,并且对所获取到的监控视频进行分析和视觉应用(包括但不限于测量测定、颜色处理、识别处理、定位引导等),为了解决监控摄像头的实时监控影像的在LabVIEW中的调用,提出了三种基于LabVIEW平台上的针对两种不同类型(ip摄像头,usb摄像头)的监控视频画面的实时调用,利用LabVIEW平台的视觉图像处理模块VDM(Vision Development Module)、视频流SDK二次开发、VLC多媒体播放器调用等技术编写程序模型,实现实时监控画面在LabVIEW中的调用。at present,the installation of various types of surveillance cameras in various industries is becoming more and more popu⁃lar,which needs real-time monitoring in traffic flow measurement,vehicle violation detection,bank security,factory operation mon⁃itoring,product processing and other aspects,as well as analysis and visual application of the obtained surveillance video(includ⁃ing but not limited to measurement and measurement,color processing,identification processing,setting In order to solve the call of the real-time monitoring image of the monitoring camera in LabVIEW,three kinds of real-time calls for two different types of monitoring video images(IP camera,USB camera)based on LabVIEW platform are proposed,and the vision development module VDM(vision development)of LabVIEW platform is used Module),secondary development of video stream SDK,call of VLC multi⁃media player and other technologies are used to write program models to realize the call of real-time monitoring screen in Lab⁃VIEW.
