Get Data From JSON Nuitrack Help!

Hi people!
Im trying to use this method tdv::nuitrack::Nuitrack::getInstancesJson to get info from users.
Im starting on this callback:

void URealSenseUserTracker::onNewUserCallback(int userId){
    qDebug() << "Debug USER ID: " << userId ;
    std::string jsondData = Nuitrack::getInstancesJson();

I can receive id from qDebug, but the json is empty everythime.

Someone know what happen?

Hi dguimaraes88,

getInstancesJson is part of Nuitrack Instance-based API. Please refer to the related documentation page.
It provides information about faces at this moment.

Face modules are by default disabled. To enable face modules, open nuitrack.config file and set Faces.ToUse and DepthProvider.Depth2ColorRegistration to true .

You should also set the value of AstraProPerseeDepthProvider.CameraID for Orbbec Astra PRO camera on Windows or Linux (usually it’s 0 , but if it doesn’t work, try 1 , 2 and so on).
