Hand World Landmarks are not accurate

[Javacr]

Have I written custom code (as opposed to using a stock example script provided in MediaPipe)

None

OS Platform and Distribution

windows 10

MediaPipe Tasks SDK version

0.10.10

Task name (e.g. Image classification, Gesture recognition etc.)

Gesture recognition

Programming Language and version (e.g. C++, Python, Java)

python

Describe the actual behavior

Hand 2D landmarks are accurate, but hand world landmarks are bad

Describe the expected behaviour

Hand world landmarks are accurate

Standalone code/steps you may have used to try to get what you need

I follow https://ai.google.dev/edge/mediapipe/solutions/vision/gesture_recognizer/python to detect hand gesture, and I plot 2D and 3D hand landmarks. The 3D hand landmarks are weird.

red represents left hand, blue represents right hand

In fact, most of the time, the results are correct. The bad results are due to the limitations of the algorithm itself.
