摘要: 泛在感知是智慧地球、智慧城市建设的基础。本文将泛在感知分为主动感知和被动感知,并分析了两类感知信息的特点,前者具有时空基准,并具有规则性、精确性和可靠性,后者通常不具备时间和空间基准支持,且数据零散、杂乱、不精确;论述了泛在感知时空基准的重要性,进而讨论了泛在感知与航天测绘的关系,并梳理了泛在感知与航天测绘融合的关键技术。

关键词: 泛在感知, 时空基准, 航天测绘, 数据融合, 知识挖掘

Abstract: Ubiquitous sensing is the foundation of smart earth and smart city construction. The ubiquitous sensing is divided into active sensing and passive sensing in this paper, and the characteristics of the two kinds of sensing information are analyzed. The former has space-time datum information which is usually regular, accurate and reliable, while the latter usually does not have the support of time and space datum, and the data is scattered, disorderly and inaccurate. The importance of spatio-temporal datum of ubiquitous sensing is discussed in order to discover the valuable knowledge, and the relationships among the ubiquitous sensing and the satellite photogrammetry as well as geographic information are analyzed, and the key technologies of the integration of the ubiquitous sensing information and satellite photogrammetry as well as the geographic information are sorted out.

Key words: ubiquitous sensing, spatio-temporal datum, satellite photogrammetry, data fusion, knowledge mining
