Abstract: A photogrammetry analysis unit of an analysis device associates the survey result obtained by a surveying device with a photographing position of each image taken by a camera, recognizes the surveying device from the image containing the surveying device, corrects the photographing position based on the known point coordinates of the surveying device, and generates the data for photogrammetry.

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 survey system including a movable photographing device, a surveying device, and an analysis device. The movable photographing device includes a camera mounted on a UAV and taking a plurality of images P for photogrammetry, and a GPS unit including a first time stamping portion stamping a first time Tc relating to a photographing time on the image P taken. The surveying device determines a position of the movable photographing device, and includes a second time stamping portion stamping a second time Tt relating to a surveying time on a survey result R determined above. The analysis device includes a photographing position analysis portion associating each survey result R with a photographing position of the respective image P based on the first time Tc and the second time Tt, and generating data for photogrammetry.
