Abstract
A bucket information acquisition device for acquiring information regarding the shape of a bucket that rotates about a rotational center axis along a predetermined moving plane in a construction machine includes: a distance distribution acquisition unit that acquires the three-dimensional distance distribution of the bucket with respect to a reference point; a reference cross section extraction unit that extracts, from the distance distribution acquired by the distance distribution acquisition unit, a reference cross section which is a cross section of the bucket obtained by cutting the bucket along a plane parallel to the moving plane; an approximate line identification unit that identifies, based on the reference cross section, an approximate line approximating the reference cross section composed of a straight line and a curve; and a bucket shape calculation unit that calculates bucket shape information regarding the shape of the bucket based on the approximate line.
