Transitioning between top-down maps and local navigation of reconstructed 3-D scenes

摘要

Technologies are described herein for transitioning between a top-down map display of a reconstructed structure within a 3-D scene and an associated local-navigation display. An application transitions between the top-down map display and the local-navigation display by animating a view in a display window over a period of time while interpolating camera parameters from values representing a starting camera view to values representing an ending camera view. In one embodiment, the starting camera view is the top-down map display view and the ending camera view is the camera view associated with a target photograph. In another embodiment, the starting camera view is the camera view associated with a currently-viewed photograph in the local-navigation display and the ending camera view is the top-down map display.

主权项

1. A computer-readable storage device having computer-executable instructions stored thereupon which, when executed by one or more computers, cause the one or more computers to:
generate a 3-D point cloud representing one of a structure or a scene computed from a collection of camera-acquired digital photographs by:
locating recognizable features that appear in at least two or more digital photographs in the collection of digital photographs, andcalculating positions of the recognizable features in space using a parameter of the recognizable features in the collection of digital photographs; display a top-down map display by projecting the positions of the recognizable features from the 3-D point cloud as points into an x-y plane; receive user input of a selected point in the x-y plane of the top-down map display; and provide an animated transition from the top-down map display to a local-navigation display showing a digital photograph from the collection of digital photographs, the digital photograph corresponding to the selected point displayed in the x-y plane of the top-down map display.
