Abstract: Classical metric navigation systems use GPS and/ or prior 2D and 3D maps for localization of manned and unmanned platforms. However, these systems do not operate in GPS challenged or denied environments. Metric map-based navigation systems are also not robust to dynamic scene changes. In this talk, we will describe various methods we have developed to incorporate AI derived semantic information into metric navigation and mapping systems. Compared to low-level metric features, semantic information is more robust to scene changes over time and can be matched across time/space/platforms. Sharing semantic information also reduces bandwidth required for collaboration/ storage. Moreover, it enables natural language interaction between humans and mobile platforms. Finally, we will discuss how the semantic information can be used by robots to learn to navigate in unmapped areas much like humans are able to visit and navigate in new, never visited before locales.
