Abstract: This disclosure relates to managing a feature point map. The managing can include adding feature points to the feature point map using feature points captured by multiple devices and/or by a single device at different times. The resulting feature point map may be referred to as a global feature point map, storing feature points from multiple feature point maps. The global feature point map may be stored in a global feature point database accessible by a server so that the server may provide the global feature point map to devices requesting feature point maps for particular locations. In such examples, the global feature point map may allow a user to localize in locations without having to scan for feature points in the locations. In this manner, the user can localize in locations in which the user has never previously visited.

Abstract: Systems and methods for localization for mobile devices are described. Some implementations may include accessing motion data captured using one or more motion sensors; determining, based on the motion data, a coarse localization, wherein the coarse localization includes a first estimate of position; obtaining one or more feature point maps, wherein the feature point maps are associated with a position of the coarse localization; accessing images captured using one or more image sensors; determining, based on the images, a fine localization pose by localizing into a feature point map of the one or more feature point maps, wherein the fine localization pose includes a second estimate of position and an estimate of orientation; generating, based on the fine localization pose, a virtual object image including a view of a virtual object; and displaying the virtual object image.

Abstract: This disclosure relates to maintaining a feature point map. The maintaining can include selectively updating feature points in the feature point map based on an assigned classification of the feature points. For example, when a feature points is assigned a first classification, the feature point is updated whenever information indicates that the feature point should be updated. In such an example, when the feature point is assigned a second classification different from the first classification, the feature point forgoes being updated whenever information indicates that the feature point should be updated. A classification can be assigned to a feature point using a classification system on one or more pixels of an image corresponding to the feature point.
