Abstract

Navigation systems combined with Augmented Reality (AR) constitute an effective solution for helping user accessing unfamiliar environments, like indoor public facilities. Implementing AR navigation systems requires determining the 6-Degrees-of-Freedom (6-DoF) localization of the user. In indoor environments, lack of Global Navigation Satellite System (GNSS) signals makes localization more challenging compared to outdoor environments. A variety of positioning systems have emerged for indoor localization which are based on several system strategies, location methods, and technologies. High-accuracy, low-cost, easy to use, and no need for any technical expertise are key features to ensure large-scale application of AR navigation systems. This study provides an answer to these key requirements by proposing a markerless infrastructure-free localization system for AR registration in indoor environments based on the comparison between a query image and a 3D mapping assumed as a reference. Since most people in public facilities are equipped with tablets or smartphone devices, they should be provided with further functionalities that will help them in day-to-day life and work. To this purpose, the proposed localization system was implemented as a web-service and tested in a university campus to assess applicability for AR registration purposes. Experiment results showed very promising localization accuracy and computational efficiency satisfying the “fine-precision” accuracy threshold (i.e., 1°/0.100 m) for near real-time AR applications.
