This disclosure describes techniques that couple panoptic reconstruction with image localization and tracking to enable users to revisit their photographs in three-dimensional augmented reality at any time after the photo is taken. A user that takes a two-dimensional photo of some scenery, e.g., a city skyline, and then, years later, revisits the spot where the photo was taken is offered a user interface, e.g., a virtual slider in the field-of-view to see a before and after comparison of how the scenery has changed since the user’s last visit. Based on location similarity, the current view is matched, and the user is provided guidance to adjust their position to obtain a close match between the photograph and their current view.
