Abstract
Systems are configured for performing GPS-based and sensor-based relocalization. During the relocalization, the systems are configured to obtain radio-based positioning data indicating an estimated position of the system within a mapped environment. The systems are also configured to identify, based on the estimated position, a subset of keyframes of a map of the mapped environment, wherein the map of the mapped environment includes a plurality of keyframes captured from a plurality of locations within the mapped environment, and the plurality of keyframes are associated with anchor points identified within the mapped environment. The systems are further configured to perform relocalization within the mapped environment based on the subset of keyframes.
