The proper execution of the sprint start is crucial in determining the performance during a sprint race. 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 ...

For the work programme BIOTOPMONITORING VIENNA of the Austrian Health Institute, multi-spectral air-borne scanner data have been recorded in the intention of automation supported identification and classification of forests and green urban areas in Vienna. Before multi-spectral and textural image analysis can be performed, the scanner data have to be geometrically rectified (georeferenced) with...

In this paper, we present various procedures to support a ZUPT-based MEMS IMU navigation application by available external building models and photographs of evacuation plans. In detail, these are approaches for horizontal alignment of the track using the external building shell, for height correction by stair and elevator detection, for the extraction of the initial position and direction usin...

MOTIVATION Foot placement and its variability can serve as indicators of mobility and walking ability as a function of age, injury, and disease in humans. Inertial measurement units (IMU) can potentially quantify foot motion without need for laboratorybased motion capture equipment, and for relatively long bouts of walking during daily living. One limitation is that integration of IMU data is s...

This paper mainly studies the structure and system of robot bionic eye. Given that most robots usually run on battery power, STM32L053C8T6 with high efficiency super low power consumption was selected as main control. By carrying IMU, eye attitude data can be acquired quickly accurately, measurement accelerometer gyroscope fused by algorithm to obtain stable accurate data. Thus, precise control...

Simultaneous Localization and Mapping (SLAM) is a process of concurrent estimation the vehicle's pose feature locations with respect to frame reference. This paper proposes computationally cheap geometric nonlinear SLAM filter algorithm structured mimic motion dynamics true problem posed on matrix Lie group $\mathbb{SLAM}_{n}\left(3\right)$. The manifold proposed in continuous form it utilizes ...

Autism Spectrum Disorders are associated with atypical movements, of which stereotypical motor movements (SMMs) interfere with learning and social interaction. The automatic SMM detection using inertial measurement units (IMU) remains complex due to the strong intra and inter-subject variability, especially when handcrafted features are extracted from the signal. We propose a new application of...

Direct georeferencing, also referred to as direct platform orientation (DPO), is defined as direct measurement of the imaging sensor external orientation parameters (EOP), using positioning and orientation sensors, such as the Global Positioning System (GPS) and Inertial Navigation System (INS) or Inertial Measurement Unit (IMU). Imaging sensors, most frequently supported by the DPO technique, ...

Inertial measurement units (IMU) are commonly used in pedestrian and robotic navigation applications and research. Although many IMUs are commercially available, almost all of them are non-customizable and they process the collected raw data before presenting them to the user. However, this creates a limitation for researchers due to the fact that they have to rely on a set of per-processed dat...
