An Optimal Fusion Method of Multiple Inertial Measurement Units Based on Measurement Noise Variance Estimation

IEEE Sensors Journal, 2023
At present, most inertial systems generally only contain a single inertial measurement unit (IMU). Considering the low cost and low accuracy of the micro-electromechanical system (MEMS)-IMU, it has attracted much attention to fuse multiple IMUs to ...

A Low-Cost Marker-Based Optical Motion Capture System to Validate Inertial Measurement Units

IEEE Sensors Letters, 2023
Commercialized marker-based optical motion capture system like Vicon is very expensive and not widely available. In the development of inertial measurement units, Vicon is required only for validation so sourcing for expensive system is undesirable.

Validation of a Spatiotemporal Gait Model Using Inertial Measurement Units for Early-Stage Parkinson’s Disease Detection During Turns

IEEE Transactions on Biomedical Engineering, 2022
Objective: Current inertial-based models were mostly limited to gait assessment of straight walking, which may not be efficient for detecting subtle gait disorders at an early stage of Parkinson’s disease (PD).

Calibration of an Inertial Measurement Unit

International Applied Mechanics, 2017
A new method for the calibration of inertial measurement units of strapdown inertial technology is proposed. Such a unit consists of accelerometers, gyroscopes, and a signal processing system. The method of test turns and rotations on a rotary table is used to calibrate the inertial measurement unit.

Calibration of an inertial measurement unit

2013 16th International Conference on Advanced Robotics (ICAR), 2013
This paper presents a fast and low cost way to calibrate different inertial measurement sensors. In particular the calibration of an accelerometer and a gyroscope using nonlinear least squares is presented. A model of the sensors which includes the main errors that MEMS devices present is used. A calibration method is proposed for estimating the static
