Abstract
A cross reality system receives tracking information in a tracking map and first location metadata associated with at least a portion of the tracking map. A sub-portion of a canonical map is determined based at least in part on a correspondence between the first location metadata associated with the at least the portion of the tracking map and second location metadata associated with the sub-portion of the canonical map. The sub-portion of the canonical map may be merged with the at least the portion of the tracking map into a merged map. The cross reality system may further generate the tracking map by using at least the pose information from one or more images and localize the tracking map to the canonical may at least by using a persistent coordinate frame in the canonical map and the location metadata associated with the location represented in the tracking map.
