Measurement of Disassembly Work Using Optical Motion Capture

open access: yes, 2023
AbstractIn recent years, the depletion of natural resources has been severe globally. One of the solutions to this problem is to reuse and recycle materials from end-of-life (EOL) products and reduce waste. In the industrial field, disassembly work is needed to take back parts/materials from the end-of-life assembly products.

Joint Center Estimation Using Single-Frame Optimization: Part 2: Experimentation

open access: yesSensors, 2018
Human motion capture is driven by joint center location estimates, and error in their estimation can be compounded by subsequent kinematic calculations. Soft tissue artifact (STA), the motion of tissue relative to the underlying bones, is a primary cause

Multiple Hypothesis Tracking for Automatic Optical Motion Capture [PDF]

open access: yes, 2002
We present a technique for performing the tracking stage of optical motion capture which retains, at each time frame, multiple marker association hypotheses and estimates of the subject's position. Central to this technique are the equations for calculating the likelihood of a sequence of association hypotheses, which we develop using a Bayesian ...

Deep Motion Features for Visual Tracking

open access: yes, 2016
Robust visual tracking is a challenging computer vision problem, with many real-world applications. Most existing approaches employ hand-crafted appearance features, such as HOG or Color Names.

Subsecond total-body imaging using ultrasensitive positron emission tomography. [PDF]

open access: yes, 2020
A 194-cm-long total-body positron emission tomography/computed tomography (PET/CT) scanner (uEXPLORER), has been constructed to offer a transformative platform for human radiotracer imaging in clinical research and healthcare. Its total-body coverage and

Turn-by-Turn Imaging of the Transverse Beam Profile in PEP-II [PDF]

open access: yes, 2006
During injection or instability, the transverse profile of an individual bunch in a storage ring can change significantly in a few turns. However, most synchrotron-light imaging techniques are not designed for this time scale.

IMU gyroscopes are a valid alternative to 3D optical motion capture system for angular kinematics analysis in tennis

open access: yes, 2020
Whereas 3D optical motion capture (OMC) systems are considered the gold standard for kinematic assessment in sport science, they present some drawbacks that limit its use in the field.

Human motion reconstruction using wearable accelerometers [PDF]

open access: yes, 2010
We address the problem of capturing human motion in scenarios where the use of a traditional optical motion capture system is impractical. Such scenarios are relatively commonplace, such as in large spaces, outdoors or at competitive sporting events ...
