LANDMARK BASED POSITIONING

摘要

Disclosed are devices, methods and storage media for use in determining position information for imaging devices or mobile devices. In some implementations, a landmark is identified in an image which is obtained from an imaging device which in turn is positioned at a location and in a pose. A virtual two-dimensional image that would be visible from the landmark is determined based, at least in part, on the pose. The location or position information is based, at least in part, on the virtual two-dimensional image.

主权项

1. A method for position estimation comprising:
identifying a landmark in an image obtained from an imaging device positioned at a location, wherein the imaging device is in a pose during a time that the image is obtained; determining, using a processor, a virtual two-dimensional image of a view from a viewpoint at the landmark based, at least in part, on the pose; and estimating the location based, at least in part, on the virtual two-dimensional image.
