Zusammenfassung:Method for detecting a boundary crossing of an object, the movement of which is represented by a sequence of positions on a digital road map ith vectorized road segments and at least one boundary, the method comprising: determining an intersection of the boundary with a road segment and a reference direction in the orientation of this road segment, successively projecting vectors, each determined between one of the positions and the intersection point, onto the reference direction, in order to obtain a sequence of projections, and detecting a boundary crossing if a change of direction or sign occurs in the sequence of projections.
