基于LabVIEW的视频监控系统的设计

中文摘要

视频监控系统当前作为公共场所或者家中安保的重要的组成部分，该系统在危险来临时，帮助人们从监控画面里的得到相关的信息，增加人们在出行时的安全系数。

本设计是通过软硬件结合的方式，利用LabVIEW 2014版本和硬件USB 摄像机相结合来实现各方面功能。论文的绪论部分对虚拟仪器进行了初步介绍，在之后的章节中介绍了与本设计相关的虚拟仪器开发软件LabVIEW。之后通过学习软件的过程中，深入学习了视觉与运动模块，并通过LabVIEW 软件完成对视频监控系统各部分功能的实现。视频监控系统主要由三部分组成分别为视频监控图像的采集、视频图像的保存、视频图像的后期处理以及自带的视频播放器进行视频的播放，最后生成EXE文件并打包生成SETUP安装程序，最终完成具有多项功能的视频监控系统。利用LabVIEW 开发的视频监控软件，在开发过程中流程较为简单，通过其中自带的函数以及控件，可以十分方便的实现系统所需要的各项功能。所以，利用LabVIEW设计的视频监控系统，在完成各项功能的同时，在日后系统功能的添加以及设备的更换方面都十分方便。

Design of the Video monitoring system Based on LabVIEW

ABSTRACT

At present,t he video monitoring system is an important link in public places or in the home security system,which can in the accident happens,get relevant information from video monitoring system in a timely manner.Increase the safety factor when people travel.

This design is a combination of hardware and software, through using the LabVIEW software 2014 and hardware of USB camera to realize the function of video monitoring system.The introduction of the paper introduces the virtual instrument, and introduces the design of the virtual instrument software LabVIEW..On the basis of the research on the visual and motion module and the corresponding function,design and write the video monitoring system through the labview software .The design of the video monitoring system is divided into a video image acquisition,video images compression and save,image post processing,and play the video through the design of the player,then generated EXE files and packaging to generate SETUP installer,finally complete the video monitor system with multiple pared with other programming software,this software operation is more convenient.There are many modules in LabVIEW can call directly, save time and effort.So, the video monitoring system designed by LabVIEW is very convenient in the function of the system and the replacement of the equipment in the future.

KEY WORDS :Video monitoring system;Video image acquisition;Video image compression and save; image post processing ;LabVIEW
