Abstract

The object of the present invention is to provide an unmanned aircraft that is capable of takeoff and landing on water while suppressing height in the vertical direction. An unmanned aircraft 1 flies with thrust produced by the rotation of propellers 60 respectively connected to a plurality of motors 50, and has a floatation member 10 that is configured to have a downwardly protruding spherical shape, and that is formed to have a greater surface area than the surface of revolution of all propellers 60 in a planar view. The floatation member 10 has through holes SH which pass through the floatation member 10 in the vertical direction, and the number of which is the same as the number of the plurality of motors 50. The propellers 60 are disposed inside the through holes SH.

Abstract

[Problem] To provide a monitoring system, a management device, a monitoring method, and a management device control program by which an intrusion drone can be found and continuously monitored even when the intrusion drone cannot be visually spotted. [Solution] A monitoring system 100 comprises: a plurality of cameras 150A, etc. which are separately disposed and are capable of photographing a common region; a management device 300 which receives images acquired by photographing performed by the cameras 150A, etc.; and an unmanned flying body 1 which is communicable with the management device 300. The management device 300 comprises: a first recognition means for recognizing the object being monitored in the images received from the cameras 150A, etc., by using artificial intelligence formed with a neural network; a position calculation means for calculating the position of the object being monitored, on the basis of the positions of the cameras 150A, etc., and the direction of the object being monitored with respect to each of the optical axes of the cameras 150A, etc.; and a position transmission means for transmitting position information indicting the position of the object being monitored to the unmanned flying body 1. The unmanned flying body 1 comprises: a flying means for making a flight to the position indicated by the position information when the position information is received from the management device 300; a photographing means for obtaining a photographed image by photographing the outside; a second recognition means for recognizing the object being monitored in the photographed image by using artificial intelligence formed with a neural network; and a lock-on means for continuously photographing the object being monitored when the object being monitored is recognized.
