mrpt::hwdrivers::CSkeletonTracker Class Referenceabstract

Detailed Description

A class for grabbing mrpt::obs::CObservationSkeleton from a PrimeSense camera.

It connects to a PrimeSense camera and tries to detect users while recording the positions of their skeletons' joints along time.

See also the application "rawlog-grabber" for a ready-to-use application to gather data from this sensor.

◆ appendObservation()

inlineprotectedinherited

◆ appendObservations()

void CGenericSensor::appendObservations ( const std::vector< mrpt::serialization::CSerializable::Ptr > &  obj)
protectedinherited

This method must be called by derived classes to enqueue a new observation in the list to be returned by getObservations.

Passed objects must be created in dynamic memory and a smart pointer passed. Example of creation:

mrpt::obs::CObservationGPS::Ptr o = CObservationGPS::Ptr( new
CObservationGPS() );
o-> .... // Set data

If several observations are passed at once in the vector, they'll be considered as a block regarding the grabbing decimation factor.
