视频监控系统开发平台的研制
中文摘要
摘要
视觉系统是人类最重要的感觉器官之一，人类所获得的大部分外界信息都来
自视觉。随着人类对自然世界的不断探索，人们总希望能够通过某种数字化机器
来实现人类视觉的功能，自动的获取外部世界的信息。随着数字图像技术的成熟，
图像监控系统随之发展起来，这对于保障工业生产、人民生活与社会安全具有重
要意义，图像监控系统已经广泛的应用于各个领域。
随着视频监控的应用范围和市场需求日趋加大，如何综合应用数字图像处理、
计算机视觉、模式识别等多项技术与传统监控相结合，设计出能够实时、持续的
主动监视场景中的运动目标并且能够对图像序列进行实用化的分析、理解和管理
的高智能化监控系统已经成为当前国内外关注的热点。目前，国际上智能监控领
域的研究已达相当水平，国内则处于刚刚起步阶段。
在这种情况和要求下，研制一个综合性的视频监控系统开发平台有着极其重
要的科研和实际意义。本论文主要研究的是一个提供了多种数据源连接的视频监
控系统开发平台，首先设计了平台的整体构架，从软件工程角度出发，详细论述
了平台实现的主要功能，性能的需求，系统开发环境的约束，并且对平台的用户
界面的设计作了详细的介绍。在平台主体研制完成的基础上，开发了游泳池监控
救生系统和射击训练系统。其中的游泳池监控救生系统是本文研究的另外一个重
点，在论文中介绍了目标溺水状态判定的具体实现算法。该算法主要以图像处理
和模式识别相关知识为依据，主要包括图像的预处理、图像特征提取和目标识别
三个部分。其中，本文提出了一种利用三个特征建立的空间上的向量距离目标识
别算法。
本文最后总结了本平台的实现结果、性能优缺点，并且针对以后可能出现的
要求和问题，对平台的进一步改进提出了展望。

Design and Research of Video Surveillance System Development
Platform
Abstract
The vision system is one of the most important organs for human being and most
information from the outside world can be acquired by it．With the continued human
exploration of the natural world，people always hope to realize human being’S vision
function by digital devices to acquire information automatically from the outside world．
Following the growing up digital image techniques，supervision system has been
developing rapidly．Supervision system has great significance for the guaranty of
industrial production，life of people and sodal security，and it has been applied in
various fields．www.751com.cn
In recent years，application range and market demand of video surveillance
increase gradually．How tO integrate digital image processing，computer vision and
pattern recognition etc．into conventional surveillance and design a smart surveillance
system which cail consecutively and automatically monitor the moving objects and
analyze，apprehend and manage the image sequences is one of hot research focuses．
Now the research in this field abroad has reached to a high level，but it just begins in our
country．
In such a background，it is very important for both scientific research and
application significance to develop an all-around video surveillance system
development platform．The major work of this paper is how to build up a video
surveillance system development platform，which provides multi．connection mode to
data sources．Platform configuration that mainly contains several parts including main
functions，capability requirement and the restrictions of development environment is
detailed in this paper，and the designs of platform interface are introduced particularly．
Based on this platform，a swimming pool surveillance system and administration system
for shooting training are built up，and the former is also another important point in this
paper·The algorithm which integrates digital image processing and pattern recognition
into the swimming pool surveillance system for drowning detection is presented in this
英文摘要
paper，and detailed in three pans including video images pre·processing，image feature
extraction and target recognition．Among the rest，a target recognition algorithm based
on the three-dimensional vector distance is given in this paper．
The summarization about the application result and performance of the platform is
presented in the last part of this paper，and the expectation about the possible
requirement and also the possible problem are given．
