Abstract
To accurately estimate a feature quantity related to a gas concentration and accurately measure a gas concentration in a space even in a case where a background temperature changes due to a factor other than gas. A gas concentration measuring deviceincludes an inspection image acquisition unitthat acquires infrared image time-series data captured by an infrared camera, a pixel specifying unitthat specifies a target pixel for gas concentration measurement and a reference pixel with a gas concentration lower than a gas concentration of the target pixel in the infrared image, a without-gas background temperature estimation unitthat estimates without-gas background temperature time-series infrared data in the target pixel based on target pixel time-series infrared data and reference pixel time-series infrared data in time-series data of the infrared image, and a concentration-feature-quantity calculation unitthat calculates time-series data of a feature quantity related to a gas concentration of the target pixel based on the target pixel time-series infrared data and without-gas background temperature time-series infrared data of the target pixel.
