A method for determining the pose of a camera (22, 32) relative to a real environment (40) comprises the following steps: taking at least one image (50) of a real environment by means of a camera (22, 32), the image containing at least part of a real object (41), performing a tracking method that evaluates information with respect to correspondences between features associated with the real object (41) and corresponding features of the real object (41) as it is contained in the image (50) of the real environment, so as to obtain conclusions about the pose of the camera (22, 32), 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.
