Abstract
A method for locating an object by a reference grid, the object moving in a plane parallel to or identical to that of the grid. When crossing of a line of the grid is detected by the object, its heading is determined and, as a function of the detection, probabilities of the thus crossed line being a horizontal line and a vertical line respectively are obtained. Displacement of the object is assessed from the probabilities obtained and a horizontal and vertical pitch of the grid. A position of the object is then updated from a position of the object determined during a last line crossing of the grid and the displacement thus assessed.
