About data generation

[yan811]

Hi! I 'd like to know some details about data generation in NPZ files.

In npz file:
1 What's the order of "pose"? SMPL pose parameter should be [24,3] dim, how did you convert it to [72,]? The order is [keypoint1_angel1, keypoint1_angle2, keypoint1_angle3, keypoint2_angel1, keypoint2_angle2, keypoint2_angle3...] or [keypoint1_angle1, keypoint2_angle1... keypoint1_angle2, keypoint2_angle2... keypoint1_angle3, keypoint1_angle3... ] ?

2 How did you generate pose into SMPL format,SPIN format , and OpenPose format?
What's the order of the second dim?
Is the keypoint order the same with SMPL model?

3 In pkl file:
For example, dim of data in './0000/camid0_videoid2/seq0/seq0.pkl' is [48,85]. What's the order of dim 1? Is it ordered by time order or shuffled?

Hi~ Thanks for your questions.

1. The order of pose is [72, ], and you can convert it to [24, 3]. The specific order can be referred to here
2. We generate pose by ROMP. You can look for the generation process from it.
3. Here is the code for generating smpl.pkl. We sorted it by time/file_name order.

Thanks for your kind and quick reply! I'll take a closer look.
