Photograph localization in a three-dimensional model

摘要

A photo localization application is configured to determine the location that an image depicts relative to a 3D representation of a structure. The 3D representation may be a 3D model, color range scan, or gray scale range scan of the structure. The image depicts a particular section of the structure. The photo localization application extracts and stores features from the 3D representation in a database. The photo localization application then extracts features from the image and compares those features against the database to identify matching features. The matching features form a location fingerprint, from which the photo localization application determines the location that the image depicts, relative to the 3D representation. The location allows the user to better understand and communicate information captured by the image.

主权项

1. A method for determining a location within a structure depicted by a first image, the method comprising:
identifying one or more features in the first image; rendering, via a virtual camera, a second image of at least one location in a three-dimensional (3D) representation of the structure; matching, via a processor, the identified features in the image with one or more features in the second image of the 3D representation of the structure; and estimating a location in the structure depicted by the image based upon the matching features identified in the 3D representation.
