hand pose, translatation and rotation parameters #22

Thanks for your great work! I have some problems when I try to ues your dataset, and hope to get your help!

  1. I find that in the /annotations/DEX_YCB_s0_train_data.json, there is also mano_param for every image. I wonder whether they are in camera frame or world frame. If I want to use the hand parameters in this json file, how can I get the parameters of the hand translation(1X3) and the object rotation and translation(4X4)?
  2. I tried to visualize the hand pose using the paramaters both in the label file and the json file, but I found neither of them was right and they were different from each other. I couldn't figure out the reason. In my opinion, even if the paramaters of the object translatation I used were wrong, the hand pose at least should be right. So the result really confused me.

Thanks again and looking forward to your reply!

This is out of context of this repo. DEX_YCB_s0_train_data.json seems to be created by the authors of the HandOccNet repo. You may want to seek answers there.

Oh, I'm sorry that I made a mistake. Thanks!
