1. A temperature distribution estimation apparatus for estimating a temperature distribution in air of a target space, the temperature distribution estimation apparatus comprising:
a thermographic camera arranged to capture a thermal image of the target space;
a camera or death sensor arranged and configured to detect a heat source in the target space;
a storage; and
a processor connected to the thermographic camera, the camera or depth sensor, and the storage,
the processor being configured to use a learning model to estimate the temperature distribution in the air of the target space based on the thermal image, the learning model being trained to input the thermal image and output the temperature distribution,
the processor being further configured to create a corrected temperature distribution by correcting the temperature distribution to reflect an influence of the heat source on the temperature distribution upon determining that the heat source is present in the target space.
