1. A thermal comfort-based air conditioning method comprising:
acquiring a thermal image of an air conditioning space via an image sensor;
acquiring thermal comfort information of a human body within the air conditioning space based on the thermal image; and
controlling air conditioning of the air conditioning space based on the thermal comfort information, wherein the acquiring the thermal comfort information of the human body comprises using an artificial intelligence (AI) model which estimates the thermal comfort information of the human body based on an analysis of a human body skin temperature feature, and
wherein the AI model is trained to extract a skin temperature feature based on at least one of a difference in the skin temperature between a finger and a palm, or a value at a pre-defined frequency band of a power spectrum of a converted signal in a frequency domain from the thermal image, and to estimate the thermal comfort information of the human body based on the skin temperature feature.
