摘　　要：为实现在LabVIEW下普通数字摄像头的驱动,介绍了一种基于VideoCapX.OCX控件实现图像采集的方法,并通过编写接口转换函数,实现了摄像头图像RGB数据的在线提取并转换为图像矩阵和NI VISION IMAQ所兼容的图像格式,以利于采用MATLAB和NIVISION工具包进行高级的图像处理和分析。为保证图像数据的实时获取和数据处理,采用了队列同步技术。实际测试结果表明,该方法可驱动市场大多数品牌数字摄像头完成图像采集,并完成图像格式的转换,实现功能扩展。To drive the common digital cameras in LabVIEW,a method of image acquisition based on VideoCapX.OCX was introduced,the RGB data of the obtained camera images can be extracted online and converted to image arrays and other data formats that compatible with NI VISION IMAQ,so that MATLAB and VISION TOOLKIT can be adopted for further advanced image processing and analysis in LabVIEW.The queue synchronous technique was adopted to ensure the real-time image data acquisition and data processing.The test result shows that it is universal for driving many brands of USB digital cameras in current market.to acquire images and to change the image types for functions extension.
