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 area setting part is configured to perform arithmetic operation for searching for an unmanned aerial vehicle having mounted therein a location identifying device using a GNSS. The UAV search area setting part includes a measured location obtaining part that obtains information of a location of the unmanned aerial vehicle, which is measured by a surveying device, a scheduled flight location obtaining part that obtains information of a scheduled flight location of the unmanned aerial vehicle from a flight plan of the unmanned aerial vehicle, and a search area setting part that sets an area for searching for the unmanned aerial vehicle by referring to a difference between the measured location and the scheduled flight location at a specific time.

First claim

What is claimed is:

1 . An operating device configured to perform arithmetic operation for searching for an unmanned aerial vehicle having mounted therein a location identifying device using a GNSS, the operating device comprising:
a measured location obtaining part that obtains information of a location of the unmanned aerial vehicle, which is measured by a surveying device; a scheduled flight location obtaining part that obtains information of a scheduled flight location of the unmanned aerial vehicle from a flight plan of the unmanned aerial vehicle; and a search area setting part that sets an area for searching for the unmanned aerial vehicle by referring to a difference between the measured location and the scheduled flight location at a specific time.

2 . The operating device according to claim 1 , wherein the measured location represents a measured altitude, and the scheduled flight location represents a scheduled altitude.

3 . The operating device according to claim 2 , wherein the difference between the measured altitude and the scheduled altitude is calculated at multiple timings, and the area for searching for the unmanned aerial vehicle is set by referring to the difference of the measured altitude and the scheduled altitude at the time closest to the time when the surveying device fails to measure the location of the unmanned aerial vehicle.

4 . The operating device according to claim 2 , wherein the difference between the measured altitude and the scheduled altitude is calculated at multiple timings, and the area for searching for the unmanned aerial vehicle is set by referring to fluctuations in the difference between the measured altitude and the scheduled altitude as time elapses.

5 . The operating device according to claim 2 , wherein a location of the surveying device is preliminarily determined by relative positioning, and the area for searching for the unmanned aerial vehicle is set by referring to a difference between the preliminarily determined location of the surveying device and a location of the surveying device that is determined at the preliminarily determined location by independent positioning.

6 . The operating device according to claim 5 , further comprising:
a comparing part that compares a difference “A” between the preliminarily determined location of the surveying device and the location of the surveying device that is determined at the preliminarily determined location by independent positioning, and a difference “B” between the measured altitude and the scheduled altitude at the specific time, with each other, and the setting of the area for searching for the unmanned aerial vehicle recited in claim 5 is performed when the result of the comparison satisfies a predetermined condition.

7 . An operating method for searching for an unmanned aerial vehicle having mounted therein a location identifying device using a GNSS, the operating method comprising:
obtaining information of a location of the unmanned aerial vehicle, which is measured by a surveying device; obtaining information of a scheduled flight location of the unmanned aerial vehicle from a flight plan of the unmanned aerial vehicle; and setting an area for searching for the unmanned aerial vehicle by referring to a difference between the measured location and the scheduled flight location at a specific time.

8 . An operating system configured to perform arithmetic operation for searching for an unmanned aerial vehicle having mounted therein a location identifying device using a GNSS, the operating system comprising:
a measured location obtaining part that obtains information of a location of the unmanned aerial vehicle, which is measured by a surveying device; a scheduled flight location obtaining part that obtains information of a scheduled flight location of the unmanned aerial vehicle from a flight plan of the unmanned aerial vehicle; and a search area setting part that sets an area for searching for the unmanned aerial vehicle by referring to a difference between the measured location and the scheduled flight location at a specific time.
