Abstract: A method, an apparatus, a device, and a medium for calibrating a temperature drift are provided. The method includes: acquiring a first measurement value and a second measurement value, the first measurement value being a measurement value of a to-be-measured quantity at a current moment determined based on an inertial measurement unit, and the second measurement value being a measurement value of the to-be-measured quantity at the current moment determined based on a global positioning system; and determining a temperature drift calibration value of the inertial measurement unit at the current moment based on the first measurement value and the second measurement value.
