摘要
实时影像监理系统是针对建筑业中信息化管理存在的不足而开发的,系统会产生大量的视频信息,如何才能够有效且快速地对这些视频信息进行检索显得至关重要,传统的基于标签的检索方式并不适用于视觉信息的检索。基于内容的视频检索(CBVR)是近年来研究的热点,本文针对实时影像监理系统的特点,对基于内容的视频检索关键技术进行了分析,介绍了系统对于各项技术的需求和应用的重点,并设计了系统中视频检索模块的基本结构。实时影像监理系统的开发是对基于内容视频检索技术应用领域的一个拓展。
Aiming at the shortage of information management in the field of construction, real-time image monitor information system is developed, and it produces a great deal of video information. It＇s very important to do video retrieval quickly and effectively, however, the traditional retrieval method based on text label is unfit for the video information. Recently,content-based video retrieval （CBVR） becomes an important research scope. In this paper, the techniques used in CBVR based on characteristic of Real-Time Image Monitor Information System are analyzed, the request on these techniques is introduced, and the structure of the video retrieval module is designed. Developing Real- Time Image Monitor Information System extends the application field of Content-Base Video Retrieval.
