Problems solved by technology

However, as the vehicle bumps, the installation angle and installation position of the inertial sensor will change, which will lead to changes in the actual data deviation. The deviation of the value is large, which makes the data accuracy of the entire inertial sensor system decrease

Abstract

An inertia sensor correction method, comprising: correcting, according to a target deviation, data output by an inertia sensor (101), wherein an initial value of the target deviation is a deviation value obtained by first correction after the inertia sensor is installed; collecting target data output by the inertia sensor when the inertia sensor is switched from a motion state to a stationary state (102); calculating a deviation value between the target data and a pre-set theoretical inertia value (103); and updating the target deviation by means of the calculated deviation value (104). Assuming that an inertia sensor is installed on a travelling vehicle, the deviation for data correction is updated in real time every time the vehicle stops, so that the problem of inaccurate deviation caused by a variation of the actual deviation after a single static correction can be effectively solved, thereby improving the data accuracy of an inertia sensor system. Further provided are an inertia sensor correction apparatus, a terminal device and a computer storage medium.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a calibration method, device, terminal equipment and computer storage medium of an inertial sensor. Background technique [0002] Inertia sensors are widely used in the field of vehicle security, and the accuracy of their data plays an important role in vehicle attitude analysis. After the inertial sensor is installed for the first time, a manual static calibration will be performed, and subsequent data calibration will be performed according to the deviation obtained from the first calibration. However, as the vehicle bumps, the installation angle and installation position of the inertial sensor will change, which will cause the actual data deviation to change. The large deviation of the value makes the data accuracy of the whole inertial sensor system decrease. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a calibration ...
