makVrv::DtTrackAcquirer Class Reference

Base class for objects that identify entities that can be tracked on screen or in the scene. Any class inheriting from this class must implement initiateTrack(), see DtLosTrackAcquirer for an example. initiateTrack() should identify and populate the DtTrackableEntities vector with entities that are within the acquisition box that is set on this object. initiateTrack() should then decide which entity from DtTrackableEntities to track. This is normally the entity closest to the centre of the acquisition box. This entity's ID is then set to the myObjectIdToTrack variable. Track acquirers are not intended to continuously check whether the identified entity is still within the acqusition box, one must pass myObjectIdToTrack into, and use a DtTrackMonitor.

Member Function Documentation

virtual bool makVrv::DtTrackAcquirer::initiateTrack ( )

virtual

Initiates the track acquirer. Override in specific acquirers. Should return true if a track is initialised. This method creates an acquisition box with default values if one has not been added to this class before init'ed a track.

Reimplemented in makVrv::DtLosTrackAcquirer.

virtual const DtTrackAcquisitionBox& makVrv::DtTrackAcquirer::trackAcquisitionBox ( ) const

virtual

Get/ Set the acquisition box.

virtual DtTrackAcquisitionBox& makVrv::DtTrackAcquirer::trackAcquisitionBox ( )

virtual void makVrv::DtTrackAcquirer::setTrackAbleEntities ( const DtTrackableEntities &  entities )

virtual

Get / Set trackable entities.

virtual const DtElementID makVrv::DtTrackAcquirer::identifiedTrackableObjectId ( ) const

virtual

Get the unique ID for the object that has been identified for tracking, returns -1 if this has not been set.
