Abstract
A portable electronic system receives a set of one or more canonical maps and determines the sparse map based at least in part upon one or more anchors pertaining to the physical environment. The sparse map is localized to at least one canonical map in the set of one or more canonical maps, and a new canonical map is created at least by merging sparse map data of the sparse map into the at least one canonical map. The set of one or more canonical maps may be determined from a universe of canonical maps comprising a plurality of canonical maps by applying a hierarchical filtering scheme to the universe. The sparse map may be localized to the at least one canonical map at least by splitting the sparse map into a plurality of connected components and by one or more merger operations.
