Abstract

A surveying system (1) comprises a target device (3) having a pole (14) and a target (15) of which distance from a lower end of the pole is known and a surveying instrument (2) capable of measuring the target, wherein the lower end of the pole is aligned with a predetermined measurement point (13), the surveying instrument is configured to calculate an O-M vector connecting a machine center of the surveying instrument and a measurement position of the target, and a M-P vector connecting the measurement position and the measurement point, to calculate an angle φ between a plane orthogonal to the M-P vector and passing through the measurement position, and the O-M vector, to calculate a measurement error between the measurement position and an optical center of the target based on the angle φ, to correct the measurement position based on the measurement error, and to calculate three-dimensional coordinates of the measurement point based on the corrected measurement position.
