PURPOSE: A monitoring system using an unmanned airship is provided to take an image using a fixed camera and a PTZ camera which clings to the lower part of an air sac and to monitor aviation photographic images on the ground. CONSTITUTION: A monitoring system using an unmanned airship comprises an air sac(1), a wire(3), a wire length control member(5), a stationary camera(7), a PTZ camera(9), a server(11), a pressure sensing member, a helium generator(15), a gas hose(17) and a pressure regulator. The air sac has a streamlined shape and is filled with helium. The wire is fixed to the boundary surface of the air sac. The wire length control member winds or unwinds a wire. The stationary camera takes a photograph of the ground at a holder which is installed the top of the wire and lower circumference of the air sac. The PTZ camera takes the image of the ground at a specific location while rotating in all directions. A server controls the PTZ camera. The pressure sensing member measures the pressure of the helium filled in the air sac. |
