Explanation

The most common reason for the projected 3D skeleton (or 3D body segments) to be consistently outside the body in the 2D videos is that there is an issue with the calibration file. The calibration of the camera system determines how the calculated 3D pose, represented by the 3D skeleton or 3D segments, is projected onto the 2D videos. Therefore, if there is an issue with the calibration file the 3D skeleton can be projected incorrectly onto the 2D videos, resulting in the skeleton or body segments appearing outside of the body.

Possible Solutions

To confirm that the calibration file is the issue, take note of whether the global coordinate system is positioned and oriented as expected in the camera view(s) for which the projected skeleton is outside the body. If the global coordinate system is not positioned correctly in one or more camera views, this confirms the issue is with the calibration file. Having confirmed the calibration file is the issue, please review the appropriate troubleshooting section for coordinate system issues.
