摘要

Image data (moving image data) indicating a plurality of infrared images obtained by capturing infrared images to be monitored for gas leakage at a plurality of times is input to the gas concentration / thickness measuring device. The gas concentration thickness product measuring device generates time-series pixel data in which pixel data of pixels at the same position are arranged in time series in a plurality of infrared images, and a predetermined number of pixels constituting the infrared image Based on the time-series pixel data of the pixels, the background temperature with gas indicating the background temperature when there is gas in the area corresponding to the predetermined pixel, and the background without gas indicating the background temperature when there is no gas in the predetermined area Determine the temperature.
