Pose Dimension in Synthetic60FPS #30

Closed Junlin-Yin closed 2 years ago

Junlin-Yin commented 2 years ago

I noticed that the dimension of pose parameter in Synthetic60FPS is 135, which according to your overview_of_published_data.txt corresponds to the SMPL pose target stored in axis-angle format. image But SMPL only has 72-D pose parameters, while SMPL+H has 156-D pose parameters. Both of them are different from your published data, so I get confused here. Could you please tell me how to extract SMPL pose parameters from the 135-D vectors?

Oh I see, you just use 15 out of 24 joints to describe a human pose. Each joint's rotation is represented by a 3x3 matrix, which accounts to 15x3x3=135 dimension.
