监控视频与地理信息融合技术发展综述

监控视频在智慧城市、平安城市的安防、管理中发挥着重要作用。虽然视频数据具有实时、直观、丰富的特点,但与地理信息的耦合分析程度不高,无法有效利用视频本身的空间信息。同时,地理信息实时性差、更新慢,无法反映动态变化的场景。为了达到更好的效果,国内外很多学者、行业人员综合两者的优势,对监控视频与地理信息的融合开展研究。本文介绍了监控视频与地理信息融合的关键技术,分析了两者融合的研究现状及应用领域,最后结合遇到的瓶颈和困难,指出了今后可能的发展趋势。

Review on the development of surveillance video and geographic information fusion technology

Surveillance video plays an important role in the security and management of smart and safe cities. Although, the video data has the characteristics of real-time, intuitive, and rich, the coupling analysis ability with geographic information is insufficient. The spatial information of the video itself cannot be effectively utilized. At the same time, due to the shortcomings of poor real-time and slow update of geographic information, it cannot reflect the dynamic scenes. In order to achieve better results, many scholars and industry personnel at home and abroad comprehensively consider their advantages and research the fusion of surveillance video and geographic information. This paper introduces the key technologies of the fusion of surveillance video and geographic information, analyzes the research status and application fields of the fusion, and finally points out the possible development trend in the future based on the bottlenecks and difficulties encountered.
