Overground gait analysis fail

New project for OpenCap, which is a new software package to estimate 3D human movement dynamics from smartphone videos. OpenCap strongly relies on OpenSim.

Overground gait analysis fail

Post by Pieter Van den Berghe » Fri Dec 13, 2024 7:58 am

I captured three overground walking conditions (c1*, c2*, c3*) after a successful calibration. The conditions are the following:
1. pre-test of normal level walking,
2. walking while wearing different clothing and materials,
3. post-test.

The overground gait advanced analysis module fails for all trials in the first condition. It runs well for conditions 2 and 3. The treadmill variant runs well, however, we would like to apply the overground analysis in all conditions for consistency. Do you have any idea why this analysis module is failing in that condition?

The session has been shared with the OpenCap admin

Hi Pieter,

Have you tried running the code locally? https://github.com/stanfordnmbl/opencap ... nalysis.py

If you can break point with these trials, you can see why they might be failing. You could break point here to see if it is getting any gait events: https://github.com/stanfordnmbl/opencap ... sis.py#L81

Hope this helps,
Matt
