摘要
基于全景图的增强地理现实平台是一种新的空间认知工具,研究其空间认知问题是进行技术研究的基础。文中介绍全景图增强地理现实的主要技术流程和优势;阐述基于全景图增强地理现实进行空间认知的基础模型;分析全景图和地理信息数据的信息匹配问题,包括比例尺和位置匹配两个方面;介绍地理信息在全景图像上的表达方式,重点解决增强目标和属性信息的选择问题;最后通过与街景地图、虚拟现实平台进行空间认知比较,得出全景图增强地理现实平台的有效性和主要适用范围,表明该平台具有独特的空间认知优势。
It is a new spatial cognitive tool that augmenting geographic reality and its spatial cognitive problems are the basis of the technology research .T his paper introduces the main technology and advantages of augmenting geographic reality based on panorama and expounds the basic model of it .Then , this paper analyzes the information matching problems between panorama and geographic information , including scale and location matching ,introduces the expression of geographic information in the panoramic ,and solves the key problems including augmented target and attribute information .Finally , through the comparison of spatial cognition with street map and VGE ,it gets the main scope of application , so w hich this platform has unique advantages for spatial cognition .
