How to get Pupillary distance? #62

Closed RickeyXiao closed 2 years ago

RickeyXiao commented 2 years ago

I am working on iOS , only find following code :

typedef NS_ENUM(NSUInteger, GARAugmentedFaceRegionType) {
  /** The region at the tip of the nose. */
  GARAugmentedFaceRegionTypeNose = 0,

  /** The region at the detected face's left side of the forehead. */
  GARAugmentedFaceRegionTypeForeheadLeft = 1,

  /** The region at the detected face's right side of the forehead. */
  GARAugmentedFaceRegionTypeForeheadRight = 2,
};

I think there should have a enum like GARAugmentedFaceRegionTypeEyeLeft, now how can i get Pupillary distance?

Look in the ARCore documentation what vertice number you need and use that position. Challenge is that the face can be from different lengths from the camera, so if you know the position and the distance between the points, what do you want to use as reference width to get the real distance between those points?

With kind regards,
