How to use Data Smoothing for tracking hands

Good morning for everyone!

I'm to trying use smoothing data with this functions below, but I haven't had success in my test, exist some examples or some explanation about this feature?

Thanks!!

Hi Jefferson,

the trick is actually in choosing the good smoothing values. We might need to improve the documentation here.

Here's an example for smoothing 3D tracking data:

// create the smoother objects

PXCDataSmoothing* smoother = NULL;
g_session->CreateImpl<PXCDataSmoothing>(&smoother);
// Creating Quadratic smoother - available options are [Spring, Stabilizer, Weightd]
m_smoother = smoother->Create3DQuadratic(0.5f);

// when you collect the tracking data - you smooth it by:

if(hand->QueryTrackedJoint(PXCHandData::JointType::SOME_JOINT_NAME,jointData) == PXC_STATUS_NO_ERROR)

{

PXCPoint3DF32 point = {jointData.positionWorld.x,jointData.positionWorld.y,jointData.positionWorld.z};

m_smoother->AddSample(point);

point = m_smoother->GetSample();

}

Thanks for your attention.

Thanks for your attention.

I'll try it.
I'm making some test with kalman filter and result was great.
