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 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: 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: When a camera and a surveying device are connected by a synchro cable, and a photographing condition obtaining unit obtains a photographing start time of the camera, a survey control unit makes a survey time measurement unit start time measurement. After the camera and the surveying device are disconnected, the survey control unit starts a survey by a predetermined surveying period ΔT when tracking of the prism starts. Based on the time measurement by the survey time measurement unit, the survey control unit associates the survey result with the photographing position of each image taken by the camera to generate the data for photogrammetry.

A measurement apparatus includes a distance measuring unit, a deflecting unit which deflects a direction of emission of measurement light with respect to a reference optical axis and which is capable of performing scanning with the measurement light with respect to a prescribed center in a circumferential direction, and a calculation control unit which controls the distance measuring unit and the deflecting unit. The calculation control unit detects coordinates of intersection points of a measurement object formed in a linear shape and a scanned trajectory of the measurement light with the basis of a distance measurement result by the distance measuring unit and the direction of emission that is deflected by the deflecting unit, and identifies an array direction of the measurement object on the basis of the coordinates of a plurality of intersection points.
