Questions about Data #67

Open ChangeNext opened 1 year ago

ChangeNext commented 1 year ago
  1. When I finished creating the data In the abs(reference1 - reference1_1).sum() part of motion representation.ipynb, I got a value of 1.1061554 instead of a zero. If I don't get a zero, I wonder if I didn't create the data correctly.

  2. I don't know what the new_joint_vecs data means. I would appreciate some clarification please.

Hi,

  1. this range of error should also be fine in my sense. You could try to visualize the results and see if it is correct or not. I know some people have made it smaller. It can be attributed to different environments and hardware platforms.
  2. The new_joint_vecs are 263-D extracted motion features. The descriptions are as follows:

root_rot_velocity (B, seq_len, 1)

root_linear_velocity (B, seq_len, 2)# root_y (B, seq_len, 1)

ric_data (B, seq_len, (joint_num - 1)3)# rot_data (B, seq_len, (joint_num - 1)6)# local_velocity (B, seq_len, joint_num*3)# foot contact (B, seq_len, 4)

Hi!I have a question about the joints. the SMPL has 23 joints and one root joint, but the humanML3D gets 22 joints,What is the difference between these two?

EricGuo5513 commented 1 year ago

We keep the first 22 joints of SMPL. The 23th and 24th joints are hand joints, which are not available in HumanAct12.
