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 enables easy recapture of an unmanned aerial vehicle (UAV) that an optical device has lost sight of. A control device controls tracking of the unmanned aerial vehicle. When failing to capture the unmanned aerial vehicle during tracking of the unmanned aerial vehicle, the control device controls processing to transmit a lost signal and controls processing to search for the unmanned aerial vehicle by targeting an airspace containing a location at which the unmanned aerial vehicle was previously captured by the control device.

Abstract: A technique is provided to more easily measure a distance of a target from a ground surface or a ceiling surface. A surveying device has a laser scanner part and a total station in a unitary manner. The surveying device includes a TS functional part, a laser scanner part, and a distance calculator. The TS functional part positions a reflective prism by using laser light. The laser scanner part performs laser scanning of a ground surface along a vertical plane containing the reflective prism and an optical axis for the laser positioning to obtain a laser scanned point cloud. The distance calculator calculates a distance between the ground surface and the reflective prism on the basis of one or multiple points, which are extracted from the laser scanned point cloud and in proximity to a straight line connecting the reflective prism and a specific plane.
