Abstract

The invention discloses an accumulative error removing method, an accumulative error removing device, a user device, and a storage medium. The accumulative error removing method comprises the steps of: selecting a to-be-selected sampling point according to a first amplitude average value of to-be-processed shaft acceleration data to determine a to-be-selected sampling point likely to reflect the rotational motion; determining a to-be-selected sampling segment according to the time interval between adjacent to-be-selected sampling points to determine a to-be-selected sampling segment likely tocharacterizes the rotational motion; selecting a to-be-processed sampling segment according to the time length of each to-be-selected sampling segment to determine a to-be-processed sampling segment which truly characterizes the rotational motion through the correlation of the data and the motion; and finally, performing filtering processing on the to-be-processed shaft acceleration data based onthe to-be-processed sampling segment. According to the accumulative error removing method, the accumulative error removing device, the user device, and the storage medium, by combining the motion principle of the data, the accumulative error is processed without combining the accelerometer and the magnetometer, the accumulative error can be effectively eliminated, and thus more accurate and reasonable data can be provided.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a cumulative error removal method, device, user equipment and storage medium. Background technique [0002] Gyroscopes, also known as angular velocity sensors, are directional instruments manufactured by using the property that when an object rotates at high speed, the angular momentum is large, and the rotation axis will always point in one direction stably. [0003] The angular velocity output by the gyroscope is an instantaneous quantity. Generally, the angular velocity cannot be used directly for attitude balance. Most inertial navigation systems control require angle signals, so angular velocity and integration time are needed to calculate the angle. The obtained angular change is added to the initial angle to get The target angle, the smaller the integration time Dt, the more accurate the output angle, but the principle of the gyroscope determines that its m...
