The application is suitable for the technical field of temperature measurement, and provides a method and device for calibrating temperature, electronic equipment and a computer readable storage medium. The method comprises: obtaining a to-be-calibrated temperature corresponding to a to-be-measured object when the to-be-measured object is in a working state; calculating a target temperature of the to-be-measured object according to a thermal emissivity corresponding to the to-be-measured object and the to-be-calibrated temperature; and taking the target temperature as an actual temperature of the to-be-measured object. Through the embodiment of the application, when a non-contact temperature measuring device is used to measure the cooking temperature of a cooking utensil, the actual temperature is obtained by calibrating and calculating the measured cooking temperature based on the thermal emissivity, the actual temperature is taken as the final cooking temperature, the accuracy of the final output cooking temperature is high, the reliability is good, and the application has strong ease of use and practicality.
