METHOD FOR DEFINING A FALL BACK ROUTE FOR A MOBILE MACHINE, METHOD OF FALL BACK, BY A MOBILE MACHINE, FOR SUCH A ROUTE, ASSOCIATED MODULES AND COMPUTER PROGRAMMES

摘要

A Method for defining a fall back route comprising of way points, for a mobile machine, in a 3D zone (ZNd) of displacement having convex zones (Zni, i=1 to 7) each describing a polygon in any plane perpendicular to a Z axis over a considered region (Hj, j=1 to 6) of a Z axis, according to which: set of beacons points (PBk, k=1 to 7) is defined, such that the edges of the Voronoi diagram associated with the said set of beacon points separate therebetween the polygons described by the convex zones in a plane perpendicular to the Z axis over the said region.

1. A method for defining a fall back route comprising of way points, for a mobile machine, in a 3D zone (ZNd) of displacement having convex zones (Zni, i=1 to 7) such that over a considered region (Hj, j=1 to 6) of a Z axis, said zones each describe a polygon in any plane perpendicular to a Z axis, said method being characterised in that it is implemented on a computer and in that it comprises the following steps i/ to ii/ relative to said region of the Z axis, in considering any plane perpendicular to the Z axis over said region:
i/ defining a set of points (PBk, k=1 to 7), referred to as beacons points for the fall back route, such that the edges of the Voronoi diagram associated with said set of beacon points separate therebetween the polygons described by the convex zones in said plane; and ii/ in a database, associating with each way point of the fall back route and each beacon point of the route, an identifier of the convex zone to which said point belongs, coordinates of said point and for each beacon point, an identifier of the said region of the Z axis.
