How to save 3D joint coordinates of the Human skeleton

1

I will like to ask if it is possible to save 3D coordinates of each joint. The aim is to save multiple human poses/skeletons in csv format. Can you please help

Hi @isola,

You can access a detected person’s 3D keypoint coordinates through the attribute sl.ObjectData.keypoint (API doc here).

This will output an array of size (18,3) representing the (x,y,z) coordinates of the following 18 joints : BODY_PARTS

Here is an example of how to access each of these joint coordinates in Python : Body Tracking tutorial

You can then save them in the format you want (text file, csv …)

Hope this helps !
