I’m using https://github.com/stereolabs/zed-sdk/tree/master/body%20tracking/body%20tracking/python .
I can reach keypoint’s position with keypoint but i can not get keypoint’s velocity or other spesific data.
I can only reach body’s spesific data. Is there any way to access the velocity data of the key point?
Hi @emrekocdemir, welcome to the forums!
You can compute these velocities yourself, they are not available as is.
The list of data available in BodyData can be consulted in the API reference of BodyData.
I thought this too but as you know there is too many data flow. Do you know how can i calculate this data. I know ı should calculate by distance difference but i dont know how much time there are between two position data. Thank you for reply.
I could not see the timestap data in this page. I tried body.timestamp or body.time_stamp but didnt work out. There is this part of zed api i could not see there too.
cdef cppclass BodyData ‘sl::BodyData’:
Thank you for your reply.
The Body Tracking module sends out Bodies, not BodyData. “Bodies” contains a timestamp and body_list, a list of BodyData. BodyData contains the keypoints, id, and other info for each detected skeleton.
Bodies is a “batch” of BodyData at a certain timestamp.
Thank you for your help this really worked out.
