TLDR
In this article, a method of determining the pose of an image capture device using a data structure corresponding to the captured image was proposed. And the method was further compared with a plurality of known data structures to identify a most similar known data structure.
Abstract
A method of determining a pose of an image capture device includes capturing an image using an image capture device. The method also includes generating a data structure corresponding to the captured image. The method further includes comparing the data structure with a plurality of known data structures to identify a most similar known data structure. Moreover, the method includes reading metadata corresponding to the most similar known data structure to determine a pose of the image capture device.
