如果你使用的是USB 摄像头，那么请参考Error! Reference source not found.Error!

Reference source not found.，运行imaqUSB examples.llb 中的Grab.vi。在软硬件正常工作的

情况下，可以看到从USB 摄像头中传出的图像，如Error! Reference source not found.所示。

在进行机器视觉系统开发前，我们通常都会如上所示先验证软硬件是否能正常工作，以

便后续开发。-NI-IMAQ for USB Cameras driver software allows users to configure any DirectShow imaging device and acquire images into LabVIEW. Devices that　support this feature include USB cameras, webcams, microscopes, scanners, and many consumer-grade imaging products.



Students and academic professionals can use this software with the NI Vision Development Module (included in the LabVIEW Student Edition) to analyze images with the aid of functions for image processing, including filters, binary morphology, pattern matching, and color inspection. The NI Vision Development Module also includes Vision Assistant for prototyping different functions, benchmarking inspections, and automatically generating code.
