PoseLandmark

  • The PoseLandmark class represents one pose landmark in a detected pose.

  • It includes a nested class summary for landmark types and a constant summary listing various body part landmarks.

  • Public methods allow retrieval of the likelihood a landmark is in the frame, its type, and its 2D and 3D positions.
public class PoseLandmark extends Object

Public Methods

public float getInFrameLikelihood ()

Gets the likelihood that a PoseLandmark is within the image frame.

It is in range [0.0f, 1.0f].

A lower in-frame-likelihood indicates that the part of the body representing this landmark is likely not visible in the frame. As a result the confidence of this prediction can be considered low.

public int getLandmarkType ()

Gets the landmark type for the PoseLandmark.

public PointF getPosition ()

Gets the 2D position of the PoseLandmark.

The return value is always non-null.

public PointF3D getPosition3D ()

Gets the 3D position of the PoseLandmark.

The return value is always non-null.

More information on the Z value:

  • The Z value is an experimental feature that returns an extra Z coordinate along with X and Y. Please note that this value is less accurate than the X and Y values.
  • The unit of measure for the Z value is the same as X and Y.
  • The smaller the Z value, the closer that landmark is to the camera.
  • Different from X and Y, Z does not have a fixed origin in the image space. The Z origin is approximately at the center of the subject’s hips. Z value will be negative if the landmark is in front of the Z origin and will be positive if the landmark is behind the Z origin.
  • The Z value does not have a fixed lower or upper bound.
