Abstract

The embodiment of the invention relates to a mobile data calibration method and device, electronic equipment and a storage medium. The method comprises the following steps: receiving historical mobiledata and historical positioning data acquired by a measurement terminal in a historical time period, wherein the historical mobile data comprises historical IMU data collected by the measurement terminal; fitting the historical movement data and the historical positioning data to obtain a nonlinear calibration function after fitting; sending the fitted nonlinear calibration function to a terminalto be calibrated, wherein the fitted nonlinear calibration function is used for indicating the to-be-calibrated terminal to calibrate initial mobile data acquired by the to-be-calibrated terminal byusing the fitted nonlinear calibration function, so as to obtain calibrated mobile data and the initial mobile data comprises initial IMU data of the terminal to be calibrated. By adopting the method,the calculation complexity can be reduced, and the calibration cost can be saved.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of data calibration, and in particular, to a calibration method, device, electronic device, and storage medium for mobile data. Background technique [0002] With the development of technology, IMU (inertial measurement unit, inertial measurement unit) is widely used in many fields. For example, in the field of automatic driving and driving behavior detection, IMU data can be used to detect the attitude of objects; in the field of aerospace and indoor navigation, IMU data can be used for real-time positioning. [0003] In related technologies, the IMU includes an accelerometer and a gyroscope, wherein the accelerometer is used to detect the three-axis acceleration of the object in the carrier coordinate system, and the gyroscope is used to detect the angular velocity of the object relative to the geographic coordinate system. However, since the IMU is often disturbed by noise, the...
