is there a way to convert the predicted 3d points to bvh?

Hi, @nkolot ,I come to notice that there exist work that convert 3d keypoints to bvh(here), but it only contain the human3.6 and cmu data structure, I have tried to modify the openpose_skeleton.py follow the h36m_skeleton.py and cmu_skeleton.py, but didn't work yet. have you also tried to get bvh from the predicted 3d points? hope you can give some advices, thanks~

Can you elaborate more on what is the issue you are facing? I haven't tried to work with bvh, but it looks that you can use the openpose_skeleton.py if you get the first 25 keypoints that we provide as output. These by definition correspond to the OpenPose keypoints.

Hi @nkolot , since in 3d animation, the usual data format is bvh ,so it's comman to convert 3d keypoints to euler and save it as bvh. I have done the openpose_skeleton.py successfully just now and convert the 3d points to final bvh, althouth the smpl fitting results look great, but the actual 3d results have some serious problems like root drifting.
