Title:
温度ドリフトの較正方法、装置、デバイス及び媒体
Document Type and Number:
Japanese Patent JP7248643
Kind Code:
B2
Abstract:
Embodiments of the present disclosure disclose a method, apparatus, device, and medium for calibrating a temperature drift, relate to on-board map technology. 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. The embodiments of the present disclosure may realize a technical effect of determining the current temperature drift calibration value of the inertial measurement unit in real time, which lays a data foundation for subsequent compensation of the temperature drift in a navigation dead reckoning algorithm, thereby improving the accuracy of a navigation result.
