Title:
INERTIA SENSOR CORRECTION METHOD AND APPARATUS, TERMINAL DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/183750
Kind Code:
A1
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.
