    Title: Estimation of joint torques and contact forces from video in rock climbing

    postdoctoral position 2019-2020

    Laboratories: LJK/GIPSA-Lab

    This postdoctoral position will explore new approaches in rock climbing motion analysis in order to
    estimate joint torques and contact forces from video. It follows previous works by Quaine et al. 2017 on
    an optimization method for simultaneous prediction of contact forces and joint torques from optical data.
    In Biomechanics, the usual experimental procedure to estimate muscle torques at joints requires to
    measure both kinematic data of the body from motion capture and contact forces with the environment
    from force sensors. While accurate, this approach is complex to deploy and limits the ability to address
    dynamics analysis in an environment such as rock-climbing mainly because of the absence of contact
    force sensors at each hold. Markerless methods are now expanding rapidly to allow an easier approach
    for kinematic analysis of body motion (OpenPose, Cao et al., 2017). In this project, we are interested in
    investigating further optimization procedure coupled with a markerless analysis in order to include
    estimation of joint torques and contact forces in the specific case of rock climbing.
    The context of the project gathers the expertise of the Math-Sports group in Applied Mathematics and
    Computer Sciences at the LJK laboratory and the Biomechanics team at GIPSA laboratory, both in
    Grenoble area, France. The project will benefit from infrastructure offered at the laboratories, such as
    high-end motion capture system and 3D dynamic scanning. In addition, a close collaboration with the
    French National Team in Climbing (FFME) will allow to investigate the application of the new methods
    in the context of training of high-level athletes.
    Position application:
    This position will be at the LJK laboratory, Grenoble, France. The LJK is a joint laboratory between
    INRIA, CNRS, Grenoble-INP and UGA. Candidate should hold a PhD related to Biomechanics,
    Computer Graphics or Computer Vision. Programming skills in C++ or Python are required. Knowledge
    of 3D modeling software such as Autodesk Maya or Blender is appreciated. Applications are to be sent
    to both Lionel Reveret and Franck Quaine (see contact below). The duration is for one year, with a
    possible extension of 6 months. Net salary is 2500 euros per month, starting in 2019.
