METHOD FOR CONTROLLING A GRAPHICAL INTERFACE FOR DISPLAYING IMAGES OF A THREE-DIMENSIONAL OBJECT

摘要

This method for controlling a graphical interface comprises: - calculating (68) the coordinates of a permanent magnet and the direction of the magnetic moment of the permanent magnet from magnetometer measurements, - matching (70) the dimensions of a three-dimensional object with the previously calculated coordinates by multiplying each dimension of the three-dimensional object by a coefficient CV in order to obtain a three-dimensional object brought to scale and by multiplying the calculated coordinates by the inverse of a coefficient CR in order to obtain scaled coordinates, - constructing (72) a two-dimensional image corresponding to the image of the object brought to scale observed from a viewpoint and along an optical axis deduced from the scaled coordinates and from the direction of the magnetic moment of the permanent magnet, and - controlling (74) the graphical interface to display the constructed image on this graphical interface.
