of local information processing method

A method (10) for processing local information acquired by means of a virtual representation of a device comprising an inertial unit and an image sensor which includes the following steps: - capturing (11) of at least one image of a real environment of the device, - location (12) of the device in the virtual representation, corresponding to the location of the device in the actual environment, by correlating portions of a captured image and portions of the virtual representation, - determining (13) the displacement of the device at least by means of the inertial unit and - modifying (15) the location of the device in the virtual representation according to the movement determined by the inertial unit for the actual position of the device corresponds, during the movement, the location of the device in the virtual representation.
