Abstract
A technique is provided to enable check of a calibrated condition of a total station (TS) having a laser scanner in a surveying site. The TS includes an optical system for sighting an object, a laser positioning part that irradiates the object with laser light via the optical system to position the object, and a plane crossing location identifying part that identifies a crossing location of multiple planes constituting a three-dimensional structure as a first location, on the basis of the positioning result from the laser positioning part. The TS also includes a laser scanner that performs laser scanning in an area containing the crossing location, a plane crossing location calculator that calculates the crossing location as a second location on the basis of laser scanning data from the laser scanner, and a comparing part that compares the first location and the second location with each other.
