bool receive ( ) #
Receives and processes one DTrack data packet.Return value
true if a DTrack data packet is received successfully, otherwise false.int getFrameCounter ( ) const#
Returns a frame counter (counting with synchronization frequency).double getTimeStamp ( ) const#
Returns the time at the measurement of the current frame, i.e. the time when the infrared flash of the cameras is fired.
