毕业设计（论文）-基于USB摄像头的图像采集系统设计【毕业论文】 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 目 录 摘 要 I ABSTRACT II 1 绪论 1 1.1 引言 1 1.2 虚拟仪器概述 1 1.3 国内外研究现状 1 1.4 课题研究的背景和意义 2 1.5 本文研究的主要内容 3 1.6 本文研究的主要任务 3 2 摄像头及USB 4 2.1 摄像头简介 4 摄像头的分类 4 摄像头的工作原理 4 摄像头的主要结构 4 2.2 USB概述 5 USB含义 5 USB的沿革 5 USB的优点 5 2.3 普通电脑摄像头实用系统设计 6 USB摄像头的安装 6 摄像头效果 6 3 VI和LabVIEW的相关简介 7 3.1 引言 7 3.2 LabVIEW：图形编程虚拟仪器 7 LabVIEW的概述 7 新VI的创建 8 3.3 虚拟仪器及视觉与运动模块 8 3.4 相关控件和函数的介绍 8 Vision控件介绍 9 Vision and Motion（视觉与运动）模块 10 4 图像采集 16 4.1 LabVIEW及
