Abstract
Disclosed herein is an optical device that determines the central coordinates of a large-diameter cylindrical structure. The optical device has the function of calculating the central coordinates of a cylindrical structure using the coordinates of a reference point of the optical device, the coordinates of a survey point on the cylindrical structure seen on the optical axis of a telescope in a state where one of right and left reference marks (e.g., a vertical line) coincides with the edge of the cylindrical structure and the optical axis is positioned on the surface of the cylindrical structure, and an aperture angle between the optical axis and the reference mark.
