Abstract:
The rapid advancement of geospatial applications on mobile devices has revolutionized outdoor activities and professions by providing invaluable tools for navigating, exploring, and highlighting geographic features. These applications often face notable challenges, including limited connectivity as well as battery and storage constraints. The objective of this paper is to provide users with a seamless user experience and augmented reality interactions in diverse outdoor scenarios within geospatial applications on mobile devices. Towards this goal, we introduce visibility map of a point that contains distances from the point to the closest obstacles at multiple angular viewpoints. We propose that every point of interest is associated with a such a visibility map, pre-calculated on a digital world model, in order to render annotated data in real-time without relying on time-consuming depth estimation. We specifically address the aspect of displaying 3D virtual information that is regis
tered at different elevations, justified by the importance of elevation information in domains such as earth science, culture science or construction and by a lack of methods that would allow that. Through our study, we demonstrate the real-time rendering capability and accuracy of our proposed method. We present the findings, discuss potential limitations, and suggest future research directions.
