通过不熟悉室内空间的独立导航为视障人士设置了障碍。因此，这一问题损害了他们的独立、自尊和自立。在这篇论文中，我将介绍一种为盲人和视障设计的新型室内导航系统，具有负担得起的成本。虽然利用全球定位系统（GPS）提供的位置信息和使用地理信息系统（GIS）的地图解决了室外车辆导航技术难题。然而，由于GPS和GIS信息不适用于室内环境，使得室内导航成为一个具有挑战性的技术难题。此外，室内导航系统的开发需要考虑到盲人用户，即需要特别注意无视觉用户界面。在这个项目中，我设计并实现了一个针对盲人和视障人士的室内导航应用程序，该应用程序利用RFID技术和计算机视觉进行定位，并通过模拟用户的行为自动生成基于环境地标的导航地图。室内导航系统的研究重点已不再局限于室内环境本身，而是盲人用户的体验方式。这个项目将尝试这个新的想法来解决盲人和视障用户的室内导航问题。

Independent navigation through unfamiliar indoor spaces is beset with barriers for the visually impaired. Hence, this issue impairs their independence, self-respect and self-reliance. In this thesis I will introduce a new indoor navigation system for the blind and visually impaired that is affordable for both the user and the building owners. Outdoor vehicle navigation technical challenges have been solved using location information provided by Global Positioning Systems (GPS) and maps using Geographical Information Systems (GIS). However, GPS and GIS information is not available for indoor environments making indoor navigation, a challenging technical problem. Moreover, the indoor navigation system needs to be developed with the blind user in mind, i.e., special care needs to be given to vision free user interface. In this project, I design and implement an indoor navigation application for the blind and visually impaired that uses RFID technology and Computer Vision for localization and a navigation map generated automatically based on environmental landmarks by simulating a user’s behavior. The focus of the indoor navigation system is no longer only on the indoor environment itself, but the way the blind users can experience it. This project will try this new idea in solving indoor navigation problems for blind and visually impaired users.
