摘要： The present invention relates to a method in a mobile device for augmented reality, which does not require markers in the real world, and comprises the steps of : receiving (200) an image of a physical real world environment taken by at least one camera at a position; receiving (210) said position; receiving (220) an id associated with said position, said id being associated with an algorithm to be used on said image to extract a set of features from said image; receiving (230) a stored set of features for said physical real world environment at said position, which has been extracted using said algorithm; extracting (240) said set of features from said image using said algorithm; and determining (250) if and how said camera is observing an object in said physical real world environment by comparing said stored set of features with said set of features. It also relates to a corresponding server and mobile device.
