【摘要】：视频变化检测广泛应用于我们日常生活的许多领域，如交通管理和森林防火。为了满足这种需求，各种算法和视频变化检测系统得到研究。早期的方法虽然有可以值得借鉴的地方，但是随着信息社会的发展，视频变化检测的需求也日益多样化。因而，现存的系统可能面临以下挑战：1）系统必须基于Web和标准接口；2）系统应该是实时或接近实时的；3）系统是按需求灵活配置的。针对以上背景，本文提出的基于标准规范的Web系统能够解决视频变化检测系统中的这些问题。这种系统能够支持实时执行，在系统架构方面具有很好的灵活性。本文使用开放地理空间联盟（Open Geospatial Consortium，OGC）的基于Web的地理处理和Sensor Web技术，提出了一种新方法来处理这样的系统。其中，OGC的Web处理服务（WPS）定义了标准的基于Web服务的地理信息处理接口。OGC的Sensor Web定义了用于共享和互操作传感器和传感器网络数据的Web服务接口。传感器观测服务（SOS）是OGC的传感网实现（SWE）服务之一，它使用标准的基于Web服务的接口来实现对传感器和传感网观测数据的管理。本文首先介绍了传感网及视频变化检测的研究背景、国内外研究现状、课题研究的目标和意义。介绍了传感网下实现视频变化检测服务的几个主要关键技术：基于SWE的传感网服务框架分析、传感网观测服务（SOS）标准接口以及基于Web Service的地理信息处理服务（WPS）操作接口。其次详细分析了视频传感器建模过程及实现，它为视频变化检测服务的实现提供信息模型支持。然后重点研究了实现视频变化检测服务的系统架构，包括实现基于实时的移动视频变化检测和基于需求的WPS处理两个子架构。最后通过原型系统，，分别从视频观测服务和视频处理服务的角度对所提出的系统架构进行了验证性实验，实验结果表明所设计的视频变化检测服务框架、模型及技术是可行的。
[Abstract]:Video change detection is widely used in many areas of our daily life, such as traffic management and forest fire prevention. In order to meet this demand, various algorithms and video change detection systems have been studied. Although the early methods can be used for reference, with the development of the information society, the demand for video change detection is becoming more and more diverse. Therefore, the existing system may face the following challenge: 1) the system must be based on Web and standard interface 2) the system should be real-time or nearly real-time) the system should be configured flexibly according to the demand. In view of the above background, the Web system based on the standard specification can solve these problems in the video change detection system. This system can support real-time execution and has good flexibility in system architecture. This paper presents a new method to deal with such a system based on Web and Sensor Web technology, which is based on the Open Geospatial Consortium (OGC). The standard Web service-based geographic information processing interface .OGC 's Sensor Web defines the Web service interface for sharing and interoperating sensor and sensor network data. Sensor observation Service (SOS) is one of OGC's sensor network implementation services. It uses a standard interface based on Web service to manage the sensor and sensor network observation data. Firstly, this paper introduces the research background of sensor network and video change detection, the research status at home and abroad, the goal and significance of the research. This paper introduces several key technologies for realizing video change detection service under the sensor network, such as the analysis of the service framework of the sensor network based on SWE, the standard interface of the observation service of the sensor network and the operation interface of the geographic information processing service based on Web Service. Secondly, the modeling process and implementation of video sensor are analyzed in detail, which provides information model support for the implementation of video change detection service. Then, the architecture of video change detection service is studied, including real-time mobile video change detection and requirement based WPS processing. Finally, through the prototype system, the system architecture is validated from the view of video observation service and video processing service respectively. The experimental results show that the proposed video change detection service framework, model and technology are feasible.
