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

Ipad unable to calibrate

Post by Tanmay Jain » Fri Aug 23, 2024 9:19 pm

Hello,
I am facing an issue in the calibration step.
My setup includes 2 Ipads, (Air 2022 and 2024 models).
I get the intrinsic for camera not found error, i could calibrate with 2 iphones smoothly, is there any possible solution to this, i've tried multiple ipad combinations but couldn't make it work. Here is the ss of the issue i am facing.

Hi Tanmay,

The newer iPads are not in our camera intrinsic libraries yet. We can let you know when they are available.

Hello,

I would also like to know about the updates to the camera intrinsic library for the newest iPads when they are available, and if possible, a rough estimate of when this can be expected :)

Thanks

Thank you for putting together such a great open source markerless motion capture system! I am having the same problem. Appreciate letting us know when the intrinsics are uploaded. Thank you!

Hi everyone!

The intrinsics for the iPad 2024 have been added. Please try collect some data and let us know if the kinematics looks good.
