Detailed Description

Derived from niftk::Single3DViewWidget to provide a widget that given a video image, will render it at video frame rate into both the foreground and the background layer, and additionally merge VTK renderings.

According to VTK documentation, layers that are not the absolute background should have a transparent background. So, by placing the VTK rendering in a layer that is NOT the background, then the black background colour should be transparent black. Then we also render the video into the foreground to try and blend over it.

In addition, this class can perform rendering, as if through a calibrated camera, such as may be obtained view an OpenCV (Zhang 2000) camera model. If the camera intrinsic parameters are found as a data node on the specified image, then the camera switches to a calibrated camera, and otherwise will assume the default VTK behaviour implemented in vtkOpenGLCamera. This only does the intrinsics, not the distortion parameters. So the supplied video should already be distortion corrected. The rendered VTK world should be distortion corrected world.

Called when a DataStorage Node Added Event was emitted.

Reimplemented from niftk::Single3DViewWidget.

void niftk::SingleVideoWidget::NodeChanged ( const mitk::DataNode * node )

Called when a DataStorage Node Changes Event was emitted.

Reimplemented from niftk::Single3DViewWidget.

void niftk::SingleVideoWidget::NodeRemoved ( const mitk::DataNode * node )

Called when a DataStorage Node Removed Event was emitted.

Reimplemented from niftk::Single3DViewWidget.

void niftk::SingleVideoWidget::resizeEvent ( QResizeEvent * event )

overrideprotectedvirtual

Re-implemented so we can correctly scale image while resizeing.

Reimplemented from niftk::Single3DViewWidget.

void niftk::SingleVideoWidget::SetDataStorage ( mitk::DataStorage * ds )

overridevirtual

Stores ds in base-class and sets it on the niftk::BitmapOverlay.

Reimplemented from niftk::Single3DViewWidget.

void niftk::SingleVideoWidget::SetEyeHandFileName ( const std::string & fileName )

If specified, will attempt to load the given file, and will assume that the provided transform is a tracking matrix, and calculate the camera-to-world transformation.

void niftk::SingleVideoWidget::SetImageNode ( mitk::DataNode * node )

overridevirtual

Overrides base class to set the selected node on the niftk::BitmapOverlay.

Reimplemented from niftk::Single3DViewWidget.

void niftk::SingleVideoWidget::SetOpacity ( const float & value )

Sets the opacity on the niftk::BitmapOverlayWidget.

Parameters

value [0..1]

void niftk::SingleVideoWidget::SetTransformNode ( const mitk::DataNode * node )

Sets a node, which should contain a niftk::CoordinateAxesData, which is used for moving the camera around.

For example, if this viewer is to render like a tracked laparoscope, then this transform node should represent the world-to-camera (i.e. tracker-to-hand, followed by hand-to-eye/camera) transform.

void niftk::SingleVideoWidget::SetUseOverlay ( const bool & b )

If true, will enable the bitmap overlay, if false, will disable it.

void niftk::SingleVideoWidget::Update ( void )

overridevirtual

Called from base class and gives us an opportunity to update renderings etc.

Implements niftk::Single3DViewWidget.
