First Claim
Patent Images
1. A method of providing a descriptor for at least one feature of an image, comprising the steps of:
- providing an image captured by a capturing device and extracting at least one feature from the image; and
assigning a descriptor to the at least one feature, the descriptor depending on at least one parameter which is indicative of an orientation in the image with respect to a projection of the direction of the gravitational force in the image,wherein the at least one parameter is determined from at least one tracking system; and
wherein the at least one parameter is determined under consideration of intrinsic parameters of the capturing device.

Abstract
A method of providing a descriptor for at least one feature of an image comprises the steps of providing an image captured by a capturing device and extracting at least one feature from the image, and assigning a descriptor to the at least one feature, the descriptor depending on at least one parameter which is indicative of an orientation, wherein the at least one parameter is determined from the orientation of the capturing device measured by a tracking system. The invention also relates to a method of matching features of two or more images.
