How to select a particular hand key-point location

rb210002

Hello there! I'm using the depthai_blaazepose_hand_tracker library for hand tracking, and I'm wondering if someone could assist me in accessing the key point of the middle fingertip. Any advice or guidance on how to access this specific data point would be greatly appreciated.

I want to access the 12 and 9 point as shown in this image. The image is from media-pipe library.

Thank you in advance for your help!

Hi rb210002
You can access points with HandRegion. Check out the hands object demo.py line 85. You can access various attributes, eg you can find pixel coordinates of each point with hands.landmarks.
Hope this helps.

Hi @jakaskerl , I tried using the hands.landmarks it is showing me an error: AttributeError: 'list' object has no attribute 'landmarks'

Hi rb210002,
Yes, in case of multi-hand tracking the result is a list which includes a HandRegion object for each hand.

Hope this helps.
