Questions for the Intel RealSense SDK Java/Processing wrapper

Hello,

I've just started playing with the F200 camera and I have a few initial questions as I began with the Java Wrapper:

  1. Is the Processing Wrapper the same thing as the Java library ? (It appears this way, but I could use a confirmation)
  2. How can I retrieve the Face landmarks using Java ? (snippet bellow)
  3. Can I use the heart rate features in Java ? If so, how ?
  4. Can I use the BlobModule in Java ? If so, how ? (snippet bellow)
  5. Where can I get an updated documentation (including what's currently supported or not in Java) ?

For Issue 2, retrieving facial landmarks, I've tried using both the non-grouped and grouped methods:

int npoints = detectData.QueryNumPoints();

PXCMFaceData.LandmarkPoint[] points=new PXCMFaceData.LandmarkPoint[npoints];

detectData.QueryPoints(points);

println(points);

This returns an empty list, similar to retrieving grouped points (which returns true):

int numPtsLE = detectData.QueryNumPointsByGroup(LandmarksGroupType.LANDMARK_GROUP_LEFT_EYE);

LandmarkPoint[] ptsLE = new LandmarkPoint[numPtsLE];

boolean hasLEPoints = detectData.QueryPointsByGroup(LandmarksGroupType.LANDMARK_GROUP_LEFT_EYE,ptsLE);

if(hasLEPoints){

for(int le = 0; le < numPtsLE; le++){

if(ptsLE[le] != null) ellipse(ptsLE[le].image.x,ptsLE[le].image.y,3,3);

}

}

println(hasLEPoints);

println(ptsLE);

prints

true

[0] null

[1] null

[2] null

[3] null

[4] null

[5] null

[6] null

[7] null

[8] null

When setting up, I've enabled landmark using the PXCMFaceConfiguration instance:

faceConfig.landmarks.isEnabled = true;

For issue 3, using hearRate, calling QueryPulse as the documentation suggests

// cfg is a PXCMFaceConfiguration instance

cfg.QueryPulse().Enable();

ends up with a NullPointerException

Exception in thread "Animation Thread" java.lang.NullPointerException

at intel.rssdk.PXCMFaceConfiguration$PulseConfiguration.Enable(PXCMFaceConfiguration.java:335)

I was expecting to write something like

faceConfig.pulse.isEnabled = true;

but pulse doesn't appear to be a property of PXCMFaceConfiguration

For issue 4, using the Blob Algorithm, I tried following the documentation:

// Create an instance of the SenseManager

PXCMSenseManager sm = PXCMSenseManager.CreateInstance();

// Enable the blob module

sm.EnableBlob();

// Get an instance of PXCMBlobModule

PXCMBlobModule blobModule = sm.QueryBlob();

but EnableBlob() isn't present. I'm guessing EnableModule(int,ImplDesc) might work,

but I'm not sure what arguments to pass. Again, QueryBlob() is missing (perhaps QueryModule(int) should be used) ? If so, how ?

Regarind issue 5, I'm trying to use as the SDK as much I can, but it would be a huge time saver

knowing what I can an can not use for now (and when to expect currently unsupported features).

I am using the latest Intel RealSense Drivers and SDK AFAIK:

Intel RealSense Depth Camera Manager F200 1.3.20.55679

Intel RealSense SDK 2014 5.0.3.187777

on Windows 8 (version 6.2, build 9200)

Thank you,

George

Ooops, my bad! I got the wrong forum, I thought I was on the Intel RealSense SDK forum.

I have posted https://software.intel.com/en-us/forums/topic/562082 there as well.

(Please feel free to remove this post (as it's now crossposted to the SDK forum).

Thank you,

George
