    摘要: 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 device 20 includes an inspection image acquisition unit 211 that acquires infrared image time-series data captured by an infrared camera 10, a pixel specifying unit 2121 that 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 unit 2122 that 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 unit 2123 that 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.

    摘要: There are provided a fixed terminal device, a control method, and a control program capable of transmitting detection data even when a communication destination is outside a communicable area of a private network. A fixed terminal device 100 is used in a communicable range with both the first and second wireless communication networks different from each other. The fixed terminal device 100 includes a sensor device, first and second reading units 130 and 140, a selection unit 601, and a transmission unit 150. The first and second reading units read authentication information for connecting to the first and second wireless communication networks, respectively. The selection unit selects which of the first wireless communication network and the second wireless communication network to transmit transmission data based on data from the sensor device. The transmission unit, after the wireless communication network selected by the selection unit is authenticated by using the authentication information, transmits the transmission data by using the wireless communication network that has been authenticated.

    摘要: A gas detection device that gives a notification of a detected gas on the basis of a captured image obtained by capturing an image of a monitoring target, the gas detection device including: a gas detection unit that detects gas on the basis of the captured image and gives a notification of the detected gas; an input unit that receives input information from a user; a mask candidate region extraction unit that extracts a mask candidate region that is a candidate region of a mask region for which a notification of gas detection is suppressed; and a mask generation unit that generates mask data indicating the mask region, in which the gas detection unit gives a notification of a gas detected outside the mask region, and the mask generation unit generates, as the mask data, a region in which first mask candidate region information input from the input unit matches second mask candidate region information extracted by the mask candidate region extraction unit.
