Industry Training sets Centre Students Apart: Logemas Vicon/Vero Workshop – 6/6/2023 

On Tuesday the 6 of June Dr Denny Wells and Scott Brennan from Logemas delivered a workshop on basic and advanced skills in VICON for the centre students at the Institute of Health and Biomedical Innovation (QUT, Kelvin Grove campus). 

Logemas is Australia’s foremost motion capture and measurement technology company, which in collaboration with the centre is working to assess the neuromechanical function of upper limbs in pre-surgical and post-surgical populations, develop new wearable technologies for optimizing functional movement, and develop VR technologies for rehabilitation. 
 
VICON software is a market-leading motion capture tool with accurate algorithms and robust real time tracking of movements from marker data. The tool is essential to the work of the centre under Program 4, led by Prof Graham Kerr with support from postdoc Wolbert Van Den Hoorn, for in vivo assessment of upper limb movements, physiology and rehabilitation as we capture movement data and assess range-of-motion from different patient cohorts.

The software works by an estimated 3D human pose from multiple synchronized 2D camera views using deep learning algorithms to capture movement effectively. This is a contrast to Traditional motion capture systems require attaching markers to specific points on the body, which can be time-consuming and restrictive. The developments from Logemas and Dr Denny Wells with markerless motion capture technology eliminate the need for physical markers, allowing for a more streamlined and intuitive approach to capturing movement with his talk ‘A Practical Guide to Markerless Motion Capture’ respectively.’ 

The basic workshop covered the system configuration set up needed for capturing data. It also detailed the system hardware from the camera all the way through to the software interface. With a focus on how to set up the system for optimal calibration and reconstruction of marker data. It further covered some of the most common problems encountered in Nexus and how to resolve the problem (Troubleshooting FAQ).  

The Advanced workshop went into depth on icon Nexus which has a wide range of analysis features available. This showcased more complex models available in Nexus (CGM2 / SCoRE SARA) encouraging participants from the centre to customise skeletons of their own projects. This facilitated focused learning of software that could be used directly on research and provided the opportunity to ask questions on specific functions from the experts.  

The workshop also explained the integration of other analysis platforms such as Matlab and cover IMU sensor integration with Vicon. Matlab, being widely used at the centre and within the field, was incredibly valuable to learn integration methods for biomechanics research.  

Overall the centre Highly values the partnership with Logemas to deliver exceptional training and development opportunities to ensure our students are industry ready. 

The centre is proud to announce several projects at the centre use Logemas’ technology as their preferred motion capture methods:
