Hello @yohanshin
The video shows walking on flat ground, but the estimated action will become walking on a slope. And the feet are higher than the ground level
Line 83 in b25b6a4
Using example videos
\examples\IMG_9730.mov
. Change the "global-R [frame_i3]" in this line of code to "default-R" to output the video from the camera at zero angle, and you will be able to see the issue I mentioned.yohanshin commented
Hi @psiydown , since WHAM does not have hard constraints on the ground conditions, its estimation does not always satisfy ground-level foot contact.

Hi @yohanshin
Is my understanding that the Y-axis offset is caused by the lack of external parameter correction for the camera? Or to adapt to the scenario of walking stairs, ignoring the hard constraints of the ground.
