TXT file in Human3.6m

[RuipengZhang118]

Hello, first of all, thank you very much for your open source code. I am a newcomer to research. Can you ask some questions? What is stored in each frame of each TXT file in Human3.6m? I am a bit confused about what is the mathematical meaning, why can I remove some data directly? thank you very much.

Hi @RuipengZhang118,

The file contains the Euler angle representation of a kinematic tree that represents the human body. With these transformations and a list of bone lengths, you can represent a pose and with a series you can represent motion.

If you are not familiar with kinematic trees, understanding this function https://github.com/una-dinosauria/human-motion-prediction/blob/c9a2774fe59bb78c6ec6d04e15f2cb7243c4348c/src/forward_kinematics.py#L14-L28 might be a good place to start.

Cheers,

I already know that every third digit from the seventh to the 99th represents an axis-angle - the process of rigid body rotation, but what does the first six numbers mean? Also how to restore a skeleton that is visible to the naked eye?For example, intuitively use three numbers to represent key point coordinates. I didn't understand your visual code. I hope you can give me some more complete theoretical materials or videos. Thank you again. @una-dinosauria

Hi @RuipengZhang118 I have the same question right now,have you work out,need your help.

I directly use the author's tools to generate the human skeleton.
