Abstract: The unmanned flying body is provided with a gas detector, a distance meter, and an altitude controller. The gas detector emits diagonally downward to the forward side in a moving direction of the unmanned flying body a detecting light frequency-modulated by a predetermined modulation frequency setting a predetermined frequency as a central frequency. The gas detector receives the light, returned from a measurement target to which the detecting light is emitted (an area on a pipe member for transferring gas, irradiated with the detecting light), as first light. The measurement target is checked for gas leakage based on the received first light. The distance meter measures the distance between the gas detector and the measurement target. The altitude controller controls the flight altitude of the unmanned flying body based on the measured distance.

Abstract: An object of the present invention is to provide a gas concentration measuring device that can accurately superimpose and display a gas concentration image and a background image so that a gas concentration distribution on the background image can be grasped at a glance. The gas concentration measuring device 1 of the present invention includes an imaging camera 20 that captures an image of a background 100, a light source 12 that emits constant light to the background, a light receiver 14 that receives light of the light source 12, a gyro sensor 30 for detecting an irradiation spot of the light of the light source 12, and a control device 40 that generates a background image based on an image capturing result of the imaging camera 20, creates a gas concentration distribution based on a light receiving result of the light receiver 14 and a detection result of the gyro sensor 30, and superimposes the gas concentration distribution on the background image.
