基于显著地标带的城市街景环境行人相对导航方法

Relative space are easier to be understood than absolute space by people. Relative orienting and navigating are basic characteristics of pedestrian navigation behaviors. GIS-based navigation theory has not made full use of relative spatial cognition and wayfinding capabilities of individual pedestrian. The discipline of spatial cognition tell us that landmark are very helpful for pedestrian to orienting and navigating process of pedestrians' wayfinding. Therefore, this project will conduct creativity research works from the perspective of relative semantic between the belt of landmarks along the navigation route and pedestrians and make full use of successive urban panoramas and digital navigation maps. It will focus on two basic science questions, namely, the understanding of salient landmark 's visual and spatial semantics, and the relative navigation theory which is based on the cognition behavior of salient landmark. This research content of this project includes: the visual and spatial semantic modeling method of salient landmarks in urban scenes, the relative navigation model of pedestrians which is based on the integrated visual and spatial semantics, and the relative navigation method through the understanding of pedestrian's cognition capability of salient landmark. This project will improve the capability of modeling and representing complicated semantics of salient landmarks, develop a relative navigation theory on the base of instinct relative characteristics of pedestrian navigation behaviors. As result, this output of this project will promote the change of navigation theory from absolute space modeling to relative and behavior-adapted navigation service, which could improve the navigation theory level and increase the comfort performance of pedestrian navigation applications.

相对空间比绝对空间更易于被人理解。行人导航本质是以相对于人的导航环境视觉与空间等相对语义来动态引导行人的过程，即相对导航。目前GIS导航理论以绝对定位与空间建模为基础，没有充分理解人对相对语义的认知差异，缺乏基于相对语义的导航理论模型。针对该问题，本项目利用对行人导航有较大辅助作用的地标，聚焦于城市街景显著地标相对语义一致性理解、行人相对导航模型等科学难点问题，结合连续多方位城市街景和导航电子地图，研究城市街景显著地标相对语义建模方法，提出基于显著地标带的相对导航模型，实现面向显著地标认知差异的个性化行人相对导航方法。项目预期发展出一个符合行人导航行为本质的相对导航理论框架，提升GIS对显著地标复杂相对语义的表达和理解能力，促进GIS导航服务从绝对空间建模到相对语义个性化服务的转变，提升导航服务的“以人为本”服务水平，提高行人导航应用舒适性。
