1. A non-contact body temperature measuring device for measuring a temperature of a human body, comprising:
a temperature measuring unit configured for measuring the temperature of the human body in a non-contact manner;
a Doppler radar configured to emit a plurality of radar waves towards the human body, and receive reflected radar waves reflected from the human body; and
a processing unit, which is electrically connected to the temperature measuring unit and the Doppler radar, being configured to determine a plurality of measurement spots on the human body based on the reflected radar waves, control the temperature measuring unit to measure temperatures of the plurality of measurement spots, and generate a body temperature measuring value based on the temperatures of the plurality of measurement spots;
wherein the processing unit is configured to obtain relative angles and relative distances between a plurality of locations on the human body and the Doppler radar based on the reflected radar waves, and to determine the plurality of measurement spots on the human body based on the relative angles and the relative distances between the plurality of locations and the Doppler radar.
