0 values for 3D key points

[jeffreyhoang]

I am trying to run triangulation and fitting the SMPL model to my own personal data. I calibrated 5 go pros and recorded myself from 5 different angles and ran triangulation on my data.

The 2D key point estimations seem to be accurate and I am able to visualize the 2D keypoints however the 3D keypoints all result in 0 values.

I was wondering if anyone had experience this same problem and was able to find a solution to it.

I've experienced this, but I forgot what I did to fix this. Did you already calibrate your camera correctly ??
