Abstract
A ground surface estimation method include: performing first estimation in which the continuous region having a largest number of the grids among the continuous regions is estimated as a ground surface; and performing second estimation including: calculating an average altitude value of the representative point of the grids in the non-adjacent continuous region for each of the non-adjacent continuous regions; calculating an average altitude value of the representative point of the grids in the predetermined range of the continuous region estimated as the ground surface; and estimating that a non-adjacent continuous region as the ground surface when a difference between the average altitude value of the representative point of the grids in the non-adjacent continuous region and the average altitude value of the representative point of the grids in a predetermined range of the continuous region estimated as the ground surface is equal to or less than a threshold.
