The present invention addresses the problem of providing a gas concentration measurement device whereby a gas concentration image and a background image can be precisely superposed and displayed, and a gas concentration distribution in the background image can be perceived at a glance. This gas concentration measurement device 1 is characterized by being provided with an imaging camera 20 for capturing an image of a background 100, a light source 12 for emitting a constant light toward a background, a photodetector 14 for receiving the 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 for generating a background image on the basis of an imaging result of the imaging camera 20, creating a gas concentration distribution on the basis of a light reception result of the photodetector 14 and a detection result of the gyro sensor 30, and superposing the gas concentration distribution on the background image. |
