Abstract
A method for calculating an angle of repose of an excavated object held by a bucket includes: calculating a bucket angle indicating an angle of the bucket with respect to a horizontal plane in a state where an inclination of a surface of the excavated object held by the bucket is maintained; measuring a weight of the excavated object; and calculating the angle of repose of the excavated object from shape data of the bucket, the bucket angle, and data of the excavated object including the measured weight.
