queryPoints() | alias has value LANDMARK_NOT_NAMED

[TSahi]

Hey everbody,

after calling the function queryLandmarks() and queryPoints(out points) I'm trying to use the Landmark names(alias) to analyse certrain face features. Unfortunately all 78 Landmarks get the name Landmark_Not_Named. According to the documentation only some enum LandmarkTypes which don't have a value are supposed to get Not_Named.

I also found another Question posted last year. Not sure if anything has changed. Does anyone have any further information or a better idea to work around it?

https://software.intel.com/en-us/forums/realsense/topic/672672 Bug: LandMarkPointSource::alias has value LANDMARK_NOT_NAMED for all face landmarks (SDK v10)

[...]

var ldata = face.QueryLandmarks();

PXCMFaceData.LandmarkPoint[] points;

if (ldata != null)

{

ldata.QueryPoints(out points);

if (points != null)

{

DrawLandmark(f);

//fake check

int cntLm = 0;

foreach (PXCMFaceData.LandmarkPoint pnt in points)

{

LandMarkPoint LP = new LandMarkPoint();

LP.ColorImageCoordinate = new IntPoint((int)pnt.image.x, (int)pnt.image.y);

LP.WorldCoordinate = new NamedVector3D() { X = pnt.world.x, Y = pnt.world.y, Z = pnt.world.z, Name = LP.Name };

if (pnt.source.alias != PXCMFaceData.LandmarkType.LANDMARK_NOT_NAMED)

{

LP.Name = pnt.source.alias.ToString();

}

else

{

cntLm++;

LP.Name = pnt.source.alias.ToString() + "_" + cntLm.ToString();

}

myFaceInfo.Landmarks.Add(LP.Name, LP);

}

Hi Talha,

We double checked with the proper department and figured out that the issue with Landmark_Not_Named is a known issue that our engineering team is aware of. However, at this moment there is no fix planned. Our apologies for any inconvenience it may cause. Regards,-Yermi A

Hey Yermi,

thanks for your reply anyways. I'll look into using sdk version 8 or try another work around then.

Edit: Where is the best place to download sdk version 8? Could you help me with that

best regards

Talha
