2D context menus

If one of the 2D (camera view) options is selected in the View context menu (that is, Sensor 0, Sensor 1, Sensor 2 or Sensor 3), and you right-click in a camera view, the following options are available:

Option

Description

Fit To Window

Fits the whole video from the current camera view to the view area.

Actual Size

Zooms the video so every pixel in the video is shown as one pixel in the view.

Start Measurement

Enables you to drag a line and display its length in pixels. This can be useful for working out which Max Radius and/or Min Radius to use for blob detection.

Clear Measurement

Clears any measurement lines from the current camera view.

Center Selection

Center the selected object(s) in the current camera view.

Frame Selection

Frame the selected object(s) in the current camera view.

Border

When selected, if Image is not selected, the 2D view displays a checkerboard pattern as the background. When not selected, the background is gray.

Image

When selected, the video image is rendered for all camera views.

Tip: For faster scrubbing, clear this option.

Detections

When selected, detections are created when the following Process menu options are selected, and are rendered in all views:

       Detect Blobs [Sequence]

       Detect Blobs [Current Frame]

       Track Forwards [Sequence]

       Track Forwards [Single Frame]

 

Points

When selected, points are displayed in all camera views.

 

Projections

When selected, projections are rendered in all the camera views. Projections will be rendered differently, depending on whether they are connected or unconnected, but neither is rendered if this option is not selected.

 

Connected

When selected, connected projections are rendered.

Note: If Projections (see above) is not selected, selecting Connected does not render connected projections.

 

Unconnected

When selected, unconnected projections are rendered.

Note: If Projections (see above) is not selected, selecting Unconnected does not render unconnected projections.

Errors

When selected, the error is rendered in the camera view. The error is the difference between the center point of a projection and its associated (connected) detection or target track in that camera view.

Blob Preview

When selected, displays a preview of the result of running Detect Blobs on the current view with the current Blob Parameters settings. This is useful for tuning these settings before running the process.

Pixel Report

When selected, a pixel report is displayed in the top-left of the camera view. The pixel report shows the current x and y coordinates of the mouse pointer in the video camera view, followed by the graylevel value (0–255). This can be useful for working out the intensity value inside and outside a blob, so you can set the Threshold correctly.

ROM

When selected, displays information from the currently loaded ROM file. (For more information, see For more information, see Initialize from a ROM file in Using Vicon CaraPost.)  

Sticks

When selected, displays any sticks in the current file. For information on creating sticks and meshes, see Create a mesh in Using Vicon CaraPost.  

Point Labels: All

When selected, displays all custom point names. For more information, see Label face markers in Using Vicon CaraPost.
