changing camera calibration setting while reprocess the data

Hello,

Is there any way to collect data using OpenCap and five cellphone cameras and later use data from different pairs of cameras when I reprocess data?
I want to figure out what is the optimized camera number and angle for my specific movement, and I am wondering if I can test it by having one trial or I should take different trials with different camera settings for this purpose.

My other question is that the model that augments the 3D marker set cannot augment any extra marker out of the marker set that it has been trained based on. Correct? So, there is no way to augment a marker on T10 (for example) with the current OpenCap pipeline?

Thanks so much for your continued support.

Hello,

1. Not out of the box, but you could reprocess your data locally https://github.com/stanfordnmbl/opencap ... essions.py and play with the source code https://github.com/stanfordnmbl/opencap ... in/main.py to do that. I had started to do something along these lines (but likely did not go to the end of my idea): https://github.com/stanfordnmbl/opencap ... l/87/files

2. No, there is a fixed set of output markers. The torso is a single rigid body though, so you will not get more information by adding T10, since you already C7 and the shoulder markers.

Best,
Antoine
