Abstract

A surveying system includes a distance measuring unit for performing the distance measurement based on the distance measuring light, an optical axis deflector configured to enable two-dimensionally deflecting the optical axis of the distance measuring light, a projecting direction detecting module for performing the angle measurement of the optical axis of the distance measuring light, and an arithmetic control module performs captures the pole by a scan pattern having a predetermined shape, acquires the point cloud data of at least two positions where the scan pattern crosses the pole, calculates an axis of the pole, calculates a direction vector, performs a linear scan along the direction vector, determines as a measuring point a point where an intersection of the optical axis of the distance measuring light and the direction vector coincides or substantially coincides with a measurement result, and calculates the three-dimensional coordinates of the measuring point.
