Patent attributes
A method of localizing a transportable apparatus (102) within an environment around the apparatus is disclosed. The method comprises obtaining a sequence of images (200) of the environment and generating one or more sequences of transformed images (204) from the sequence of images wherein an image from the sequence of images has undergone a transformation to provide a transformed image within the sequence of transformed images. Processing circuitry (112) is then used to compare one or more images from the sequence of transformed images (204) and one or more images from at least one of the sequence of images (200) and a further sequence of transformed images against a representation of the environment. The comparison determines corresponding features within the images (200) and/or transformed images (204) and the representation. The transportable apparatus (102) is then localized according to a position of the one or more corresponding features.
