Abstract
A columnar object state detection device according to an embodiment is a device for detecting a state of a columnar object including: an acquisition unit configured to acquire central axis data that is an array of coordinate values of center points of the columnar object in a horizontal direction at a plurality of predetermined heights of the columnar object; an approximation equation calculating unit configured to calculate a correction approximation equation for correcting the coordinate values of the central axis data acquired by the acquisition unit through curve fitting for the array of coordinate values of the central axis data acquired by the acquisition unit; and correction unit configured to correct the coordinate values of the acquired central axis data using the correction approximation equation calculated by the approximation equation calculating unit.
