基于USB摄像头的图像采集系统设计 摘 要 NI公司的LabVIEW是当前流行的图形化开发环境，同时它也是一种功能强大的编程语言（亦被称为“G”语言）。它使创建的程序模块化，易于调试、理解和维护，而且程序编程简单、直观。因此它特别适用于图像采集处理系统。而USB总线以其使用方便、传输速度快、即插即用、通用性强、扩展性好和性价比高等优点得到广泛的应用。把LabVIEW语言和USB摄像头紧密结合起来产生的图像采集系统，将集成两者的优点。 基于USB摄像头的图像采集系统设计，将其分为图像采集、图像保存和生成EXE文件三部分。首先，本文论述了虚拟仪器发展、特点以及研究现状，详细的介绍了虚拟仪器以及其代表软件LabVIEW。并指出了USB摄像头相关知识以及它的优缺点，在此基础上研究了视觉与运动模块与相应的结构，设计了编写LabVIEW应用程序的方法与步骤，最终达到了预期的设计效果，并生成了EXE文件。总之，系统的设计，保证了系统的准确性、实用性，且具有成本低廉和开发周期短等特点。 关键字：LabVIEW，USB摄像头，图像采集和保存 Based on the USB Camera Image Acquisition and Control System ABSTRACT NI company is currently popular LabVIEW graphic development environment, it is also a powerful programming language (also known as G language). It makes create program modular, easy to debug, understanding and maintenance, and simple, intuitive programming. Therefore, it is especially applicable to image acquisition and processing system. And with its convenient USB bus, transmission speed, plug and play, strong commonality, scalability, good and high performance-to-price advantages to get extensive application. Put LabVIEW language and USB camera combining image acquisition system, will integrate the advantages of both. Based on the USB Camera Image Acquisition and Control System can be divided into image acquisition, image save and create EXE file there parts. First, this paper discusses the development of virtual instrument, characteristic and research status, detailed introduces the virtual instrument and its representative LabVIEW software. And points out the USB webcam related knowledge and its advantages and disadvantages, based on this research the visual and movement module and the corresponding structure, design the LabVIEW applications written method and step, finally achieve the expected design effect, this design also created EXE file. Anyhow, the system designs ensure that the system is practical, and the accuracy, with low cost and short development cycle, etc. KEY WORDS: LabVIEW, USB camera, image acquisition and storage
