摘要: 三维虚拟旅游系统通常以提供沉浸式游览体验为主要目的,不能提供关于旅程的信息服务,难以满足用户的个性化需求。为此,提出基于IBeacon低功耗蓝牙通信技术的室内定位方法,在室内文化游览设施中提供室内定位和自动导览功能。该方法基于RSSI测距原理和平面投影的三维空间定位技术,支持通过手机接收IBeacon蓝牙基站发射信号实现快速定位。结合IBeacon室内定位方法与在线三维虚拟旅游系统,形成虚实结合、线上线下一体化的文化旅游虚拟导览系统,为游客提供线上虚拟体验、线下实时定位和基于位置的信息服务。应用结果表明,该系统的室内定位速度较快且精度满足应用要求,可为游客提供良好的旅游体验。

Abstract: The 3D virtual tour system often provides immersive tour experience.It cannot offer information service about tour and is hard to fulfill users’ personalized requirement.To tackle this issue,an indoor positioning method based on IBeacon Bluetooth communication technology with low consumption is proposed to provide indoor positioning and automatic tour-guidance service in indoor culture tourist facilities.It is based on RSSI ranging principle and plane projection-based 3D space positioning technology,and supports receiving transmission signals from IBeacon Bluetooth base station by mobile phone to realize fast positioning.This paper applies IBeacon-based indoor positioning method in online 3D virtual tour system,and establishes an online-to-offline cultural tour guidance system combining virtuality with reality,which provides tourists with online virtual experience,offline realtime positioning and location-based information service.Application results show that the proposed system has higher speed of indoor positioning and accuracy fulfilling application requirement.It can provide users with better travel experience.

Key words: virtual reality, virtual tour, indoor positioning, IBeacon technology, 3D Geographic Information System(GIS)
