Hi, the scale values vary across the datasets, but do not change on the same dataset. That is, 3dpw_train_occ_db.pt and 3dpw_train_db.pt are generated using the same scale (1.2) as written in the released code files.
We applied different scales across the datasets, because the size of bounding box annotations were too different. For example, bounding boxes of one dataset appeared to be too tight, but these of another dataset appeared to be too loose. But the overall performance does not change much though,

@hongsukchoi I noticed that in one issue you said that the scale written in the released code files was 1.2. But it seemed that in the source code of 3dpw, the scale was set to 1.3. https://github.com/hongsukchoi/TCMR_RELEASE/blob/8078b3c39c22cae39eb19c0e1eb70e09c60ecea7/lib/data_utils/threedpw_utils.py#L157-L158 Thanks!
Hi! Yes, you are right for the repr_table4_3dpw_model.yaml
setting.
h36m_train_25fps_occ_nosmpl_db.pt correspond to 1.2, that of 3dpw _train_occ_db.pt corresponds to 1.2, and that of 3dpw_val _db.pt
No, the scales vary on other benchmarks. For example to follow the bbox setting of SPIN in H36M, we use tighter bbox.
i.e. all the 3d datasets used are scaled to 1.2
I cannot remember why the default setting is like that :( use 1.2 for 3dpw
But it seemed that in the source code of 3dpw, the scale was set to 1.3.
Thank you for your detailed reply!
Hello. Thanks for your great work! I want to do some different processes for original data. To ensure data consistency, I have to ensure the parameter 'scale' in different 3d datasets. I use the
repr_table4_3dpw_model.yaml
as config file. And the corresponding datasets are listed below. https://github.com/hongsukchoi/TCMR_RELEASE/blob/8078b3c39c22cae39eb19c0e1eb70e09c60ecea7/configs/repr_table4_3dpw_model.yaml#L31-L35 https://github.com/hongsukchoi/TCMR_RELEASE/blob/8078b3c39c22cae39eb19c0e1eb70e09c60ecea7/lib/dataset/_dataset_3d.py#L92-L99 Does scale ofh36m_train_25fps_occ_nosmpl_db.pt
correspond to 1.2, that of3dpw _train_occ_db.pt
corresponds to 1.2, and that of3dpw_val _db.pt
corresponds to 1.2 (i.e. all the 3d datasets used are scaled to 1.2)? Did I say anything wrong? I'm not quite sure because in thethreedpw_utils.py
, the default scale is set to 1.3. https://github.com/hongsukchoi/TCMR_RELEASE/blob/8078b3c39c22cae39eb19c0e1eb70e09c60ecea7/lib/data_utils/threedpw_utils.py#L157-L158 Thanks!
