METHOD FOR DETERMINING THE POSE OF A CAMERA AND FOR RECOGNIZING AN OBJECT OF A REAL ENVIRONMENT
First Claim
1. A method for recognizing an object of a real environment in an image taken by a camera, said method comprising the following steps:
- taking at least one image of a real environment by means of a camera, the image containing at least part of a real object;
performing an image recognition method providing information as to the recognition of the at least one real object in the image;
determining at least one parameter of an environmental situation; and
performing the image recognition method in accordance with the at least one parameter.

Abstract
A method for determining the pose of a camera relative to a real environment includes the following steps: taking at least one image of a real environment by means of a camera, the image containing at least part of a real object, performing a tracking method that evaluates information with respect to correspondences between features associated with the real object and corresponding features of the real object as it is contained in the image of the real environment, so as to obtain conclusions about the pose of the camera, determining at least one parameter of an environmental situation, and performing the tracking method in accordance with the at least one parameter. Analogously, the method can also be utilized in a method for recognizing an object of a real environment in an image taken by a camera.

-
taking at least one image of a real environment by means of a camera, the image containing at least part of a real object; determining at least one parameter of an environmental situation; performing a tracking method that evaluates information with respect to correspondences between features associated with the real object and corresponding features of the real object as it is contained in the image of the real environment, so as to obtain conclusions about the pose of the camera; and performing the tracking method in accordance with the at least one parameter; wherein, by determining the camera pose, depth information with respect to at least one real object contained in the image is calculated, the depth information being used to compute an occlusion model for a real object, when virtual information superimposed on the real environment is occluded in the view by the real object.
