Abstract: A survey system includes a survey device and a target. The survey device includes a main body rotatable around a vertical axis, a telescope supported by the main body and rotatable around a horizontal axis, a wide angle imaging unit having a second angle of view wider than a first angle of view of the telescope, and a target identification unit configured to identify a target image. The target image is identified based on a differential image between a first image captured by the wide angle imaging unit during an on-period with laser light emitted from an emission unit and a second image captured during an off-period in which laser light is not emitted from the emission unit. The target image is quickly identified even when the target is significantly separated in the horizontal direction from a position directly in front of the survey device.

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.

Abstract: In measurement with a surveying device having a surveying function and a laser scanner function, three-dimensional coordinates of a reflecting prism acquired with the surveying function and three-dimensional coordinates of a vertex of a polyhedron generated by processing point group data acquired with the laser scanner function are made to coincide with each other. The reflecting prism is used together with the surveying device having the surveying function and the laser scanner function, is provided to a measurement target object, and is disposed in such a position that the vertex position of the measurement target object coincides with or is considered to coincide with the optical center position of the prism.

Abstract: A technique is provided for measuring attitude of an aerial vehicle without using an IMU. A total station (TS) for tracking a UAV includes a laser scanner. The laser scanner is made to emit laser scanning light to the UAV that is flying. The UAV has four identifiable targets, and identification and locating of the four targets are performed by means of laser scanning. The attitude of the UAV is calculated on the basis of the locations of the four targets.
