Markerless motion capture research to be presented at International Society of Biomechanics 2021
We are really excited to hear that CAMERA Research Associates Laurie Needham, Logan Wade and Murray Evans have had abstracts accepted at the Virtual XXVII Congress of the International Society of Biomechanics in Stockholm.
Laurie, Logan and Murray’s work focuses on how applications of markerless motion capture may significantly reduce the time required to collect and process data, enabling body positions of athletes and patients to be extracted by simply walking or running in front of the cameras, without the need for markers to be placed on their body. This technology could enable coaches and clinicians to easily obtain highly detailed information about the movements of their athletes and patients without the need for highly trained individuals to collect and process the data.
“We have developed and evaluated a markerless motion capture method to generate fused 3D skeletons from calibrated high-speed multi-camera image data and have used this method to explore the performance of several popular 2D pose estimation algorithms (OpenPose, AlphaPose and DeepLabCut’s pre-trained human pose model). To evaluate each 2D pose estimation algorithm within our markerless motion capture method, we have evaluated the 3D joint centre positions against joint centres derived from marker-based motion capture during walking, running, and jumping. Further analysis has then compared clinical gait metrics such as step length, step width and 2D planar hip and knee joint angles, to explore the applicability of these current pose estimation algorithms for clinical application in comparison to marker-based methods.”
Huge congratulations to Laurie, Logan and Murray. The XXVIII Congress of the International Society of Biomechanics is the first virtual conference in the history of the ISB and will feature 4 days of scientific presentations from 25th to 29th July 2021. More information and registration.
