Microsoft patents method to match image sections across camera views
Microsoft describes a computer method that splits two photos taken by real cameras into smaller grid sections. It then finds matching visual details in these sections to identify which parts of the second photo are spatially close to a specific part of the first photo.
In the filing’s own words
Digital image processing methods performed by a computer are disclosed. In one example, a first digital image captured by a real camera is sub-divided into a first plurality of sub-images. A second digital image captured by a real camera is sub-divided into a second plurality of sub-images. A set of image features in a first sub-image of the first plurality of sub-images is identified. A subset of neighboring sub-images is identified from the second plurality of sub-images based at least on each neighboring sub-image of the subset of neighboring sub-images having one or more corresponding image features in common with the set of image features identified in the first sub-image.
What exactly they claim (claim 1)
1. A digital image processing method performed by a computer, the method comprising: receiving a first digital image captured by a real camera having a first set of intrinsic parameters and extrinsic parameters; sub-dividing the first digital image into a first plurality of sub-images, each sub-image of the first plurality of sub-images having a corresponding set of synthesized intrinsic parameters and extrinsic parameters that are mapped from the first set of intrinsic parameters and extrinsic parameters of the real camera that captured the first digital image; receiving a second digital image captured by a real camera having a second set of intrinsic and extrinsic parameters; sub-dividing the second digital image into a second plurality of sub-images, each sub-image of the second plurality of sub-images having a corresponding set of synthesized intrinsic parameters and extrinsic parameters that are mapped from the second set of intrinsic parameters and extrinsic parameters of the real camera that captured the second digital image; identifying a set of image features in a first sub-image of the first plurality of sub-images; and identifying a subset of neighboring sub-images from the second plurality of sub-images based at least on each neighboring sub-image of the subset of neighboring sub-images having one or more corresponding image features in common with the set of image features identified in the first sub-image.
