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: Provided is a three-dimensional position measuring system, a three-dimensional position measuring method, and a measuring module with which measurement can be performed without a special operation constraint even in state where a measuring module is inclined. The three-dimensional position measuring system includes a measuring module that includes a target, an omnidirectional camera, and a triaxial accelerometer, and is grasped a positional relationship among the target, the omnidirectional camera, and a measurement point, and a surveying instrument including a light output section that outputs light toward the target and a measurement section that performs distance measuring and angle measuring to the target. Since the measuring module including the target is equipped with the omnidirectional camera and the triaxial accelerometer, a posture direction of the measuring module can be identified.

Abstract: A technique for more reliably capturing a lost unmanned aerial vehicle in tracking the unmanned aerial vehicle by a surveying device is provided. A UAV search controlling part configured to be used in a search for an unmanned aerial vehicle that flies along a predetermined flight path includes an estimating part and a search controlling part. The estimating part estimates, on the basis of location data of a surveying device that surveys a location of the unmanned aerial vehicle by using laser light and on the basis of the predetermined flight path, a direction of the unmanned aerial vehicle as seen from the surveying device at a specific time. The search controlling part controls to allow the surveying device to search for the unmanned aerial vehicle, on the basis of the estimated direction.

Abstract: Provided is a survey system capable of acquiring point group data of a three-dimensional object desired to be measured without complicated setting. A survey system includes a surveying instrument including a tracking section that tracks a target by emitting tracking light and receiving the tracking light reflected on the target, and a scanner that rotates horizontally and integrally with the surveying instrument and performs scanning around a single axis in a vertical direction, and the scanner and the tracking section are offset in the horizontal direction. Therefore, a scanning line (SL) does not match the target, and is always controlled around the target.
