Abstract: A technique for preventing decrease in accuracy of measuring a tilt angle of a surveying device is provided. A total station includes a rotating unit, a horizontal angle measuring unit, a tilt sensor, and a tilt amount calculating part. The rotating unit has a distance measuring unit that performs optical surveying, and the rotating unit horizontally rotates. The horizontal angle measuring unit measures a rotation angle of the horizontal rotation of the rotating unit. The tilt sensor measures a tilt of the rotating unit relative to the direction of gravity. The tilt amount calculating part calculates a tilt of the rotating unit on the basis of measured values of the horizontal angle measuring unit before and after the rotating unit rotates.

Abstract: Disclosed is a measurement device including: a distance measurement unit that has a light-generating element, a measurement light emission unit, a light reception unit, and a light reception element and measures a distance to a measurement target on the basis of a light reception signal; a deflection unit that is capable of performing scanning with measurement light; and a control unit that controls the distance measurement unit and the deflection unit. The control unit finds a surface of the measurement target, generates a grid having lines that are arranged at regular intervals on the surface of the measurement target and include a component parallel to a reference direction and a component perpendicular to the reference direction, and controls a deflection behavior of the deflection unit so that a scanning track of the measurement light traces the lines of the grid.

Abstract: A technique is provided to enable reduction in cost relating to installation of orientation targets in aerial photogrammetry. A survey data processing device includes a positioning data receiving unit, a relative orientation unit, an absolute orientation unit, and an adjustment calculation executing unit. The positioning data receiving unit receives positioning data obtained by tracking and positioning a reflective prism of an aerial vehicle by a total station. The aerial vehicle also has a camera. The relative orientation unit calculates relative exterior orientation parameters of the camera by relative orientation using photographed images taken by the camera. The absolute orientation unit provides a true scale to the relative exterior orientation parameters by absolute orientation using the positioning data and the relative exterior orientation parameters. The adjustment calculation executing unit corrects the relative exterior orientation parameters having the true scale, by using a positional relationship between the camera and the reflective prism.

Abstract: A technique for reliably locking on a UAV in tracking the UAV by an optical device is provided. The location of a total station (TS) is measured, and location information of a UAV during hovering is obtained from a GPS unit that is mounted on the UAV. On the basis of the location of the TS and the location information of the UAV during hovering, the TS calculates the direction of the UAV as seen from the TS to capture the UAV.
