【摘要】：智能导游是基于游客位置的路径引导、游览讲解的综合性服务,与地理信息系统(GIS)、移动定位技术、基于位置的服务(LBS)等之间有着密切的联系。随着我国旅游市场的快速发展和旅游信息化建设的不断推进,强调信息化、定量化的数字旅游、数字景区逐步向强调人性化、智能化服务的智慧旅游、智慧景区建设转化。我国传感网、物联网技术的迅速发展同样加快了这一领域的建设。但是基于传统室外定位(如GPS)为主的车载定位导航难以满足同时具有室外景点与室内展区、展品的景区导游服务,因而室内外一体化定位、导航技术及其在智能导游领域的应用亟待研究。本文旨在将室内外定位技术、方法引入到景区导游服务系统中,从游客时空位置获取、行为分析的角度探讨景区智能导游的室内外一体化定位及其位置服务技术与方法,研究如何构建以GPS、蓝牙和超宽带(Ultra-Wide Band, UWB)定位为基础、可同时满足游客室外和室内一体化路径引导和信息讲解需求的景区智能导游服务方法。基于位置服务及导游学相关理论知识,研究景区智能导游的服务模式、服务构成及特点,提出景区智能导游的体系架构,探讨景区智能导游过程中的室内外定位、室内外游览路径规划引导和室内外景点信息讲解等方法和技术问题,并构建相应原型系统对上述问题进行验证,在此基础上进行应用示范。论文的研究有助于推动移动GIS在旅游行业应用中的理论和技术创新,为旅游服务特别是导游服务的定位、引导和讲解提供一种全新的技术支撑,同时也为拓展景区导游服务模式及方法体系提供新的思路。总结起来,本文在如下几个方面开展了研究： (1)对智能导游与位置服务的内蕴联系进行分析,按智能导游获取服务方式的不同,将景区智能导游划分为离线服务、无线网络服务和混合服务三种不同的导游服务模式。分析智能导游服务的业务构成及特点,从更加注重服务游客的整体游览体验-室内外无缝游览、室内外游览路径引导和室内外实时信息播报等方面出发,提出整合室内外定位、游览路径引导服务、系统讲解服务以及其它景区生活设施查询服务的景区智能导游体系架构。阐述景区智能导游的服务内容,并指出其中的室内外定位是基础,而游览路径规划和景点信息讲解是景区智能导游服务中最为重要和关键的组成部分。最后从与现有景区信息化平台集成方面讨论景区智能导游的建设思路。 (2)在调研室内外定位技术的基础之上,分析各种定位方法的定位精度、适用范围和定位可集成性等性能参数,根据景区智能导游系统中室内外定位的具体需求,研究基于GPS、蓝牙和UWB的室内外组合定位方法。本文系统的梳理上述定位的特点,并对景区室内外数据的空间基准进行统一。在此基础之上探讨影响室内外定位切换的三大因素,即建筑物因素、定位设备因素以及人的行为状态因素。提出基于游客行为与空间状态的室内外组合定位模式,通过探测游客的运动状态实现定位切换算法,构建基于GPS与UWB的室内外组合定位平台。 (3)依托景区道路网数据模型,在A*算法等经典最优路径算法的支持下,提出基于景区智能导游的联合分段游览路径规划思想(简称联合分段路径规划),通过将景区智能导游的游览路径划分为由室外路段与室内路段交替衔接的组合体,室外路段自起始点开始至室内景点入口为止,室内路段自室内景点入口至出口点为止,在联合分段游览路径规划主算法、景区游览道路搜索子算法和联合分段游览路径规划子算法的支持下,实现了景区智能导游的室内外游览路径规划。实验结果表明,在室内采用顺序游览和随机游览时,联合分段游览路径规划的结果是合理的,该方法具有现实的可用性。 (4)基于空间对象的位置信息描述参数和空间关系计算模型,在位置语义描述句法规则的支持下,实现以游客自身作为参照物的空间对象位置信息动态描述。依托于室内外定位技术获取的游客实时位置信息,提出一种基于室内外景点播报区域的实时景点信息播报方法,将游客的实时位置与播报区域之间的空间关系作为景点讲解的触发条件,并对不同类型的景区目标采用不同的播报区域划分方法；指出游客在景区游览过程中存在的三种游览方式及其之间的转换关系,实现游客偏离游览线路时的处理方法；针对导游过程中路口播报与景点讲解相冲突的问题,提出一种适时延后或提前播报路口转向信息的处理方法,该方法具有算法复杂度低,可操作性强的特点。 (5)对上述智能导游服务相关理论、一体化定位平台、室内外游览路径规划模型及景点信息实时播报方法进行系统实现,基于嵌入式移动智能终端平台,设计并实现了尚湖景区智能导游服务系统。对论文中提出的相关体系架构和服务模型、方法进行有效性验证,结果表明,基于室内外一体化定位及其位置服务的景区智能导游具有景点讲解自然流畅、路口播报及时准确、偏离线路提醒和处理恰当等特点,能够满足游客在景区范围内的各种导游服务需求,可以在景区大批量投入使用,同时也可以推广到其它相关景区。
[Abstract]:The intelligent tour guide is based on the route guidance of the tourist location, the comprehensive service of the tour explanation, and the close connection with the geographic information system (GIS), the mobile positioning technology and the location based service (LBS). With the rapid development of the tourism market and the continuous promotion of the construction of tourism information, the information and quantitative digital brigade are emphasized. With the rapid development of our country's sensing network and the rapid development of the Internet of things technology, the rapid development of China's sensing network and the Internet of things technology has also accelerated the construction of this field. However, the vehicle positioning and navigation based on the traditional outdoor positioning (such as GPS) is difficult to meet the outdoor scenic spots and indoor exhibition areas at the same time. In this paper, the interior and exterior positioning technology and its application in the field of intelligent tour guide are urgently studied. This paper aims to introduce the indoor and outdoor positioning technology and method into the tourist guide service system, and discuss the indoor and outdoor integration of the intelligent tour guide from the perspective of the tourist location and behavior analysis. The technology and method of location and location service are used to study how to build an intelligent tour guide service method based on GPS, Bluetooth and Ultra-Wide Band (UWB), which can simultaneously meet the tourists' outdoor and indoor integration path guidance and information explanation requirements. Based on the theory of position service and tour guide, the intelligence of scenic spots is studied. The service mode, the service composition and the characteristics of the tour guide, put forward the architecture of the intelligent tour guide in the scenic area, explore the indoor and outdoor positioning of the intelligent tour guide in the scenic spot, the guidance of the indoor and outdoor tour route planning and the information explanation of the indoor and outdoor scenic spots and so on, and build the corresponding prototype system to verify the above problems. The research of this paper will help to promote the theory and technology innovation of mobile GIS in the tourism industry, provide a new technical support for tourism service, especially guide service orientation, guide and explanation, and also provide new ideas for developing tourist guide service mode and square law system.
To sum up, the following studies have been carried out in this paper.
(1) to analyze the inner link of intelligent tour guide and position service, according to the difference of the way of obtaining the service of intelligent tour guide, the intelligent tour guide is divided into offline service, wireless network service and mixed service three different guide service modes. The structure and characteristics of the intelligent tour guide service are analyzed, and the overall attention is paid to the overall service of the tourists. Tour experience - indoor and outdoor sightseeing, indoor and outdoor tour guide and indoor and outdoor real-time information broadcast, and so on, put forward the integration of indoor and outdoor positioning, tour route guidance service, system explanation service and other scenic spot inquiry service of scenic area intelligent tour guide system architecture. It is pointed out that the indoor and outdoor positioning is the basis, and the tour route planning and the information explanation of scenic spots are the most important and key components in the intelligent tour guide service of the scenic area. Finally, the construction ideas of the intelligent tour guide in the scenic area are discussed from the integration of the existing scenic area information platform.
(2) on the basis of the investigation of indoor and outdoor positioning technology, this paper analyzes the positioning accuracy of various positioning methods, the scope of application and the integration of positioning and other performance parameters. According to the specific requirements of indoor and outdoor positioning in the intelligent tourist guide system in scenic spots, this paper studies the indoor and outdoor combination positioning method based on GPS, Bluetooth and UWB. This paper systematically combs the above positioning The spatial datum of the indoor and outdoor data in the scenic area is unified. On this basis, the three factors affecting the indoor and outdoor location switching are discussed, namely, the building factors, the positioning equipment factors and the human behavior status factors. The indoor and outdoor combination positioning mode based on the tourist behavior and the space state is put forward to detect the tourists' movement form. In order to realize the location and handover algorithm, an indoor and outdoor integrated positioning platform based on GPS and UWB is built.
(3) relying on the data model of scenic road network and under the support of the classical optimal path algorithm such as A* algorithm, this paper proposes a joint segmented tour route planning idea based on Intelligent tourist guides in scenic spots (referred to as joint segmented path planning), and divides the tour path of intelligent tour guides in the scenic area into a combination of outdoor sections and indoor sections alternately. Under the support of the main algorithm of the joint section tour route planning, the road search subalgorithm and the joint subsection route planning sub algorithm, the indoor and outdoor tour route planning of the scenic tourist tourist guide is realized. The results show that the results of the combined segmented tour path planning are reasonable in the indoor use of sequential tour and random tour, and this method has practical usability.
(4) based on the spatial object location information description parameter and the spatial relation calculation model, under the support of the position semantic description syntax rule, it realizes the dynamic description of the spatial object location information with the tourist itself as the reference. Based on the indoor location technology, a kind of indoor location based on the indoor location information is proposed. The information broadcast method of real time scenic spots is reported in the area. The spatial relationship between the real time position of tourists and the broadcast area is used as the triggering condition for the explanation of the scenic spots, and the different broadcasting area division methods are adopted for different types of scenic spots, and the three ways of sightseeing and the transition between the tourist in the scenic spots are pointed out. In order to realize the handling method when tourists deviate from the tour routes, in view of the conflict between the broadcast of the intersection and the explanation of the scenic spots in the course of the tour guide, a method to deal with the turning information at the right time or in advance is proposed. This method has the characteristics of low complexity and strong operability.
(5) on the above intelligent tour guide service theory, integrated positioning platform, indoor and outdoor tour route planning model and scenic spot information real-time broadcasting method, based on embedded mobile intelligent terminal platform, the intelligent tour guide service system in Lake scenic area is designed and implemented. The related system architecture and service model proposed in this paper are put forward. The results show that the intelligent tour guide based on the indoor and outdoor integration positioning and location service has the characteristics of natural fluency, timely and accurate interpretation of the intersections, deviation from the line reminding and proper handling, and can meet the tourist needs of various tourist guides in the scenic area, and can be in large quantities in the scenic spots. Put into use, but also can be extended to other related scenic spots.
