[摘要] 智能化人群监控是智能视频监控研究中的一个重要课题,它作为智能监控中的一项关键技术,在人群管理、公共场所设计、虚拟环境建模、视觉监控、智能环境模拟等方面都有着重要的应用价值。
随着经济社会的发展,各种公共场地和设施中的人群流动越来越频繁。如何对公共场合的人群进行有效管理与控制,是不得不考虑的重大问题。智能化人群监控技术应运而生,它主要包括人群的密度估计和运动估计两部分内容。本文着手解决人群运动估计这一块,智能化运动估计可以用于人群的监测和管理,也可应用于商业领域,如市场调查、交通安全以及建筑设计领域等。它们能够直接或间接地提高上述场合工作人员的工作效率和建筑设施的利用率,因此对人群密度估计和运动估计方法的研究有着深远的意义和广阔的前景。
本文结合OpenCV,采用块匹配算法对人群的运动进行估计,并在功能实现前对OpenCV与块匹配各重要环节有具体分析。

[Abstract] Intelligentized crowd surveillance tecllIlology is an important research sub—field in intelligem video surveillance a key tecllnology of intelligent surveillarlce,it is of great value in a large number of applications such as crowd management,public space design virtual environments simulate,visual surveillanlce,intelligent enviroments aIlalysis,etc.
With the development of economic society, the crowd in various kinds of public places flows more and more frequently. How to manage and control the crowd es to be an important issue which we have to consider nowadays. Intelligentized crowd surveillance technology arises at the very moment. It mainly includes both density estimation and motion paper set about the crowd motion estimation. Intelligentized crowd motion estimation can be used for monitoring and managing the crowd, at the same time, it can also be used for market survrey in mercial field,traffic safety and architectural design field,etc. it can help staff members in the above mentioned occasions improve working efficiency and improve utilization ratio of building facilities directly or indirectly,so there is far-reaching meaning and wide prospect in crowd’s density and motion estimation research.
According to OpenCV, this paper use BMA(Block Matching Algorithm) for crowd motion estimation,and before the function r
