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: 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 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.

Abstract: In a gas detection device and a gas detection method of the present invention, detection target gas is detected on the basis of reflected light of detection light (sensing light) frequency-modulated with respect to a center frequency and a distance to an object that generates the reflected light is measured. In the gas detection, an output signal of a light reception unit for receiving the reflected light is subjected to phase-sensitive detection. A synchronous detection timing of this phase-sensitive detection is adjusted on the basis of the measured distance to the object.

Abstract: This gas imaging device makes it possible to photograph gas without placing a burden on a user while enhancing the evidential reliability of imaging results. This gas imaging device comprises: an infrared imaging section for imaging, under a predetermined first photography condition, infrared radiation from a given area from which gas could leak; an image processing section for generating an image of the given area on the basis of output results from the infrared imaging section; and a control section for, on the basis of vicinity information for the given area and the output results of the infrared imaging section, calculating a reliability indicating whether the first photography condition is suitable for photography of the gas and storing an image of the given area in a storage section in association with at least one from among the reliability and the vicinity information.

Abstract: In a gas detection device and a gas detection method of the present invention, frequency-modulated detection light is irradiated while being scanned, a light reception output signal obtained by receiving reflected light of the detection light is subjected to phase-sensitive detection, a resulting detection output signal is sampled, and detection target gas GA is detected on the basis of a sampling result. A modulation frequency of the detection light is controlled on the basis of a scanning speed.
