Study of IMU Installation Position for Posture Estimation of Excavators

Position Estimation using Inertial Measurement Unit (IMU

In this respect, when moving from the crouch to the upright position, trunk kinematics is a key element. The purpose of this study was to validate the use of a trunk-mounted inertial measurement unit (IMU) in estimating the trunk inclination and angular velocity in the sagittal plane during the sprint start.

Attitude and gyro bias estimation by the rotation of an

Oct 27, 2015 · Conclusion. In this paper, a novel method for attitude and gyro bias estimation is proposed. The principle of the method is to combine measurements from an IMU consisting of a gyro and accelerometer when rotating the IMU around a pre-calibrated axis in a controlled manner independent from the rigid body motion.

A Novel Application of Inertial Measurement Units (IMUs

Sep 06, 2014 · [18] used a gyroscope to estimate the posture of a mobile inverted pendulum. For drift correction in that case, a tilt sensor was fused with the gyroscope. In spaceflight, NASA uses accelerometers to detect and null errors generated in IMU devices. The accelerations caused by the earth are definitely known, and any discrepancies are considered

1. Introduction

With the development of AR/VR and control technology, object pose estimation is needed in manifold scenes. A large number of low-cost small embedded platforms also need to carry out object spatial pose estimation, such as in the exhibition, education, and other fields [1, 2].At present, most of the estimation of object pose depends on the binocular camera [3] or RGB-D …
