Abstract
Technologies are described herein for generating and displaying top-down maps of reconstructed structures to improve navigation of photographs within a 3-D scene. A 3-D point cloud is computed from a collection of photographs of the scene. A top-down map is generated from the 3-D point cloud by projecting the points in the point cloud into a two-dimensional plane. The points in the projection may be filtered and/or enhanced to enhance the display of the top-down map. Finally, the top-down map is displayed to the user in conjunction with or as an alternative to the photographs from the reconstructed structure or scene.
