ABSTRACT:
Distance meters measure distances from a reference position to a first area including an upper pitch circle portion and a second area including a lower pitch circle portion. Center coordinates of the hub is calculated based on respective center coordinates of two hub bolts included within the first and second areas. Coordinates of three points defining apexes of a triangle are acquired. Inclination angle of the hub relative to a vertical plane is calculated based on the coordinates of the three points, and an orientation of each of the hub bolts is calculated based on the center coordinates of the hub and the center coordinates of the hub bolt.
