Use Java code to capture landmarks points

Hi guys.

I tried to make some test in relasense camera using the java language.

Below the code.

I tried to capture de landmaks but the java program return the null points.

Why?

import intel.rssdk.PXCMCaptureManager;
import intel.rssdk.PXCMFaceConfiguration;
import intel.rssdk.PXCMFaceData;
import intel.rssdk.PXCMFaceModule;
import intel.rssdk.PXCMSenseManager;
import intel.rssdk.PXCMSession;
import intel.rssdk.pxcmStatus;

public class TesteLandMark {

	public static void main(String[] args) {
		// Create session
		PXCMSession session = PXCMSession.CreateInstance();
		if (session == null) {
			System.out.print("Failed to create a session instance\n");
			System.exit(3);
		}

		PXCMSenseManager senseMgr = session.CreateSenseManager();
		if (senseMgr == null) {
			System.out.print("Failed to create a SenseManager instance\n");
			System.exit(3);
		}
		
		PXCMCaptureManager captureMgr = senseMgr.QueryCaptureManager();
		captureMgr.FilterByDeviceInfo("RealSense", null, 0);

		pxcmStatus sts = senseMgr.EnableFace(null);
		
		if (sts.compareTo(pxcmStatus.PXCM_STATUS_NO_ERROR) < 0) {
			throw new IllegalStateException("Failed to enable face");
		}

		PXCMFaceModule face = senseMgr.QueryFace();
		PXCMFaceConfiguration cfg = face.CreateActiveConfiguration();
		cfg.EnableAllAlerts();

		cfg.ApplyChanges();
		cfg.close();
		
		sts = senseMgr.Init();
		
		while (senseMgr.AcquireFrame(true) == pxcmStatus.PXCM_STATUS_NO_ERROR) {	
			  PXCMFaceModule face2 = senseMgr.QueryFace();
			  
			  PXCMFaceData faceData = face2.CreateOutput();
			  faceData.Update();
			  int numFaces = faceData.QueryNumberOfDetectedFaces();
			  System.out.println("Saw: " + numFaces + " faces.");
			  for (int i = 0; i < numFaces; i++)  {
				  // Retrieve the face landmark data instance
				   PXCMFaceData.Face face1 = faceData.QueryFaceByIndex(i);
				   PXCMFaceData.LandmarksData ldata = face1.QueryLandmarks();
				   
				   // allocate the array big enough to hold the landmark points.
				   int npoints = ldata.QueryNumPoints();
				   PXCMFaceData.LandmarkPoint[] points = new PXCMFaceData.LandmarkPoint[npoints];
				   
				   // get the landmark data
				   ldata.QueryPoints(points);
				   
				   for(PXCMFaceData.LandmarkPoint p: points){
					   if(p != null){
						   System.out.println("points x: " + p.image.x);
						   System.out.println("points y: " + p.image.y);
					   }
				   }
			  }
			  faceData.close();	
			  senseMgr.ReleaseFrame();
		} 
	}
}

Which camera are you using?

Hi David

Below the information about the SDk. The camera is RealSense F200

Intel(R) RealSense(TM) SDK 8.0.24.6528
Intel(R) RealSense(TM) SDK Runtime 6.0.21.6598
Intel(R) RealSense(TM) Depth Camera Manager 1.4.27.41944
Intel(R) RealSense(TM) 3D Camera 2780

I tryed pick up the landmarks position but the code bring the points null.

// get the landmark data
ldata.QueryPoints(points);
for(PXCMFaceData.LandmarkPoint p: points){
                       if(p != null){
                           System.out.println("points x: " + p.image.x);
                           System.out.println("points y: " + p.image.y);
                       }
                   }
              }

Thanks
