摘要
随着室内移动位置服务的快速发展,人们对室内地图表现效果提出更高的要求。但是传统的室内地图表现手法单一,多是以二维平面示意图为主。针对这一问题,采用WebGIS与WebGL技术,对导览系统设计、室内空间构建及室内路径导航进行研究,形成室内空间构建、路径导航功能实现的一套完整流程,实现室内地图导览、同楼层和跨楼层的混合空间表达、实时切换,规划导航等通用需求。解决用户室内寻路难点,为人们在室内空间自由活动提供了高效便利的位置服务指引。并以医院作为示例,制作了导览系统样例,验证系统设计与实现的合理性。
With the rapid development of indoor mobile location services,people put forward higher requirements for indoor map performance.But the expression of traditional indoor map shows a single way,mostly based on two-dimensional plane sketch.For this question,this paper used the technology of WebGIS and WebGL to study the design of navigation system,the construction of indoor space and the navigation of indoor path.It formed a complete flow of indoor space construction and navigation function,realized indoor map navigation,the expression of mixed space of the same floor and cross-floor,real-time switching,planning guidance and other general requirements.It solved the difficulties of indoor route finding and provided a convenient and efficient location service guide for people to move freely in indoor space.Taking a hospital as an example,we made a sample guide system.It verified the rationality of the design and implementation of the system.
