PATH PLANNING DEVICE AND PATH PLANNING METHOD

WIPO Patent Application WO/2024/009537

A1

The present disclosure provides a path planning device comprising: a first acquisition unit that acquires a pillar erection position and the position of an obstacle; a mapping unit that applies the acquired pillar erection position and the position of the obstacle to a map of the vicinity of a work location, and sets a work area of a prescribed size centered on a position a prescribed distance away from the acquired pillar erection position; a second acquisition unit that acquires the number of divisions into which the work area is divided; a planning unit that uses a combination of all the coordinates for placing heavy equipment and all the coordinates for laying down to-be-erected utility poles within the work area divided according to the number of divisions acquired by the second acquisition unit to generate a path plan from the coordinates where heavy equipment is to be placed to the pillar erection position via the coordinates where the to-be-erected utility pole is to be laid down, and to aggregate the search success probability and path travel time in each path plan and convert the same into points; and a display unit that displays a heat map of the points aggregated for each of coordinates where heavy equipment is placed.
