    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 flying vehicle has a retro-reflector, a position measuring instrument has a non-prism measurement function for performing a distance measurement and an angle measurement in non-prism and a prism measurement function for performing the distance measurement and the angle measurement with respect to the retro-reflector, a control device is adapted to have a flight range as set within a flat plane, to prepare an approximate flight plan having a two-dimensional approximate flying route as set within the flight range, to measure the approximate flying route by the non-prism measurement, to calculate a three-dimensional detailed flying route based on the measurement results and the approximate flying route, to prepare a detailed flight plan including the detailed flying route and to control the flying vehicle so as to fly in maintaining a distance between the flying vehicle system and a surface of the object to be measured at a constant value based on the detailed flight plan and a result of the prism measurement.
