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

Automatic calibration for inertial measurement unit

2012 12th International Conference on Control Automation Robotics & Vision (ICARCV), 2012
The nine degrees-of-freedom (DOF) inertial measurement units (IMU) are generally composed of three kinds of sensor: accelerometer, gyroscope and magnetometer. The calibration of these sensor suites not only requires turn-table or purpose-built fixture, but also entails a complex and laborious procedure in data sampling.

Analysis and modelling of MEMS inertial measurement unit

2012 International Conference on Localization and GNSS, 2012
Thanks to advances in the development of Micro-Electromechanical Systems (MEMS), it has been possible to fabricate small dimension and cheap accelerometers and gyros, which are being used in many applications where the GPS/INS integration is carried out, as for example to identify track defects, navigation, geo-referencing, agriculture, etc.

Inertial Measurement Unit for Trajectography

2021 2nd International Conference on Range Technology (ICORT), 2021
This document presents a technological breakthrough regarding electro-optics systems used for accurate measurement of the position of flying objects in Test Ranges. The innovation presented here consists in using an “Inertial Measurement Unit” (IMU) installed as close as possible to the optronic sensors in the core of the payload.

Measuring Arm Motions Using the Inertial Measurement Unit

2020 IEEE 2nd Global Conference on Life Sciences and Technologies (LifeTech), 2020
This paper describes how to detect arm motions using Inertial measurement unit (IMU). The authors propose a method to attach the IMU to an upper arm and a lower arm as so to obtain the arm’s attitude information from the sensor’s data and thereby to detect the arm’s motions. Our experiment has shown that the arm’s flexion can be detected.

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.

Internal calibration of a camera and an inertial measurement unit

2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
In this paper, we address the problem of internal calibration of a camera and an inertial measurement unit (IMU). The internal calibration of a camera and an IMU requires the determination of the relative orientation and displacement between the camera and the IMU.
