Detailed Description

Base class for receiving images from a video stream.

Subclass to implement for a specific protocol. Supported messages:

  • Image : contains vtkImageData, timestamp, uid, all else is discarded.
  • ProbeData : contains sector and image definition, temporal cal is discarded.

Member Function Documentation

void cx::ImageReceiverThread::addImageToQueue ( ImagePtr  imgMsg)
protected

Add the message to a thread-safe queue. Tests if the time stamps of image messages should be calibrated based on the computer clock. Time stamps only need to be synched if set on another computer that is not synched, e.g. the Ultrasonix scanner

Parameters
[in]imgMsgIncoming image message

void cx::ImageReceiverThread::addSonixStatusToQueue ( ProbeDefinitionPtr  msg)
protected

add the message to a thread-safe queue

Definition at line 142 of file cxImageReceiverThread.cpp.

void cx::ImageReceiverThread::calibrateTimeStamp ( ImagePtr  imgMsg)
protected

Calibrate the time stamps of the incoming message based on the computer clock. Calibration is based on an average of several of the last messages. The calibration is updated every 20-30 sec.
