How to save the result of Body Tracking as .json or .skeleton?

[ibaiGorordo]

I have just added support, you can do: json.dumps(body_frame.json())

I have also added the json() function to body, so something like this is also possible

bodies = body_frame.get_bodies()
json.dumps(bodies[0].json())

Thank you very much!

Thanks for your help ! Excuse me. Could you please tell me how to save the position [x y z] of  joints in a action like the appendix?It really bothered me for a long time. 甄帅 @.***

I don't understand your message fully, but I have added a numpy() method () that will return the joint positions like a numpy array. From there, i think you should be able to save it however you like.

Example:

bodies = body_frame.get_bodies()
print(bodies[0].numpy())

Output:

hi Is this data Millimeter value of xyz?

[ibaiGorordo]

Yes, and here is the list of which joint refers to each row: https://github.com/ibaiGorordo/pyKinectAzure/blob/538111ccbe1c0c19151ed742e143bf32a0d90978/pykinect_azure/k4abt/_k4abtTypes.py#L25
