METHOD AND SYSTEM FOR CALIBRATING COMPONENTS OF AN INERTIAL MEASUREMENT UNIT (IMU) USING SCENE-CAPTURED DATA

Document Type and Number:

WIPO Patent Application WO/2018/025115

Kind Code:

A3

Abstract:

A method and a system for calibrating an inertial measurement unit (IMU) via images of a calibration target are provided herein. The method may include: measuring parameters via an IMU; capturing a plurality of calibration images of a scene that contains at least one calibration target, wherein the calibration images are taken from different locations and/or orientations, wherein each of the calibration images shares a common calibration target with at least one other calibration image; calculating, based on the at least one common calibration target, a position and orientation of the sensing device relative to the calibration target, for each location of the capturing of the calibration images; and calibrating the IMU by comparing relative motion between two of the calibration images based on the calculated relative position and orientation, to measurements of the parameters taken by the IMU in time ranges corresponding to the at least two calibration images.
