Abstract
A method and system for enabling a self-localizing mobile device to localize other self-localizing mobile devices having different reference frames is disclosed. Multiple self-localizing mobile devices are configured to survey an environment to generate a three-dimensional map of the environment using simultaneous localization and mapping (SLAM) techniques. The mobile devices are equipped with wireless transceivers, such as Ultra-wideband radios, for measuring distances between the mobile devices using wireless ranging techniques. Based on the measured distances and self-localized positions in the environment corresponding to each measured distance, at least one of the mobile devices is configured to determine relative rotational and translational transformations between the different reference frames of the mobile devices. Based on the determined transformations, the mobile devices are able to localize the other mobile devices in their own reference frames, which can enable a variety of spatially aware augmented reality features and interactions.
