question about smpl issue (smpl twisted in some frames)

[leilaUEA]

I have used a 3 camera dataset as an input, the smpl model in most of the frames are fine, in some frames it get twisted, does it happen because of openpose problem and occolusion?I wonder if we have two camera on each side (i.e. 5 cameras instead of 3) that would solve the issue?

here is smpl reprojection of continuous frames, the left arm openpose key points are miscalculated in the second camera for few frames

first camera:

second camera

third camera

It seems that the optimization falls into local optimal and generates a bad result.

it was also mentionedif model is smpl the optimization doesn't use nose keypoints, don't know if it affected the result

Maybe fixed in current version.
