Abstract

The invention provides a sensor calibration method, device, equipment and medium. The method comprises: obtaining three-dimensional attitude information detected by a target sensor, the target sensor comprising an acceleration sensor, a geomagnetic sensor and a gyroscope; reading a calibration deviation value of the target sensor from a memory, wherein the calibration deviation value is a deviation value which is obtained by calibrating the three-dimensional attitude information of the target sensor according to the attitude filtering algorithm and accords with preset precision; and calibrating the three-dimensional attitude information through the calibration deviation value according to an attitude filtering algorithm to obtain target three-dimensional attitude information. The calibration efficiency is improved by reading the calibration deviation value of the target sensor from the memory.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a sensor calibration method, device, equipment and medium. Background technique [0002] At present, some head-mounted display devices or handles related to virtual reality (Virtual Reality, referred to as VR), augmented reality (Augmented Reality, referred to as AR), etc., usually detect the rotation of the head in different directions, that is, the detection device is in X, Y, The angle value of the rotation on the Z axis calculates the displacement of the device, and guides a specific part of the panoramic image to be displayed following the head movement. However, before using these devices, it is generally necessary to go through the 3 degrees of freedom (3DOF for short) mode of rotation angles, that is, acceleration 6-plane calibration, gyroscope static calibration and geomagnetic 8-figure calibration to achieve initial positioning. However, these calibrations usually need to be re-...
