An electronic device generates a summary map of a scene based on data representative of objects having a high utility for identifying the scene when estimating a current pose of the electronic device and localizes the estimated current pose with respect to the summary map. The electronic device identifies scenes based on groups of objects appearing together in consistent configurations over time, and identifies utility weights for objects appearing in scenes, wherein the utility weights indicate a predicted likelihood that the corresponding object will be persistently identifiable by the electronic device in the environment over time and are based at least in part on verification by one or more mobile devices. The electronic device generates a summary map of each scene based on data representative of objects having utility weights above a threshold.

Map summarization and localization

A method of determining a registration between Scanworlds may include determining a first viewpoint of a setting based on first point data of a first Scanworld. The first Scanworld may include information about the setting as taken by a first laser scanner at a first location. The method may further include determining a second viewpoint of the setting based on second point data of a second Scanworld. The second Scanworld may include information about the setting as taken by a second laser scanner at a second location. The method may further include generating a first rectified image based on the first viewpoint and generating a second rectified image based on the second viewpoint. Additionally, the method may include determining a registration between the first Scanworld and the second Scanworld based on the first viewpoint and the second viewpoint.
