Classification Viewer
Classification Viewer Functionality
The Classification Viewer is the main panel used while working with classified point clouds.
To open the Classification Viewer, go to the Review and Optimize section and select the icon above.
Classification Table Options
Class Name
Before running classification, all points will be categorized as Created, never classified. Once points have been classified, all classes that have points will be visible.
If the Setups are classified and not hidden, the Classification Viewer will show the classes that have points on them.
Visibility
By default, all present classes will be visible, selecting the eye icon will turn that class off. Selecting the visible header will turn all visibility for all classes on or off.
Colour
The user can change the color of any class by clicking the colour icon next to the desired class and selecting a colour from the menu that appears.
Override Colour
In some cases, users may want to display point clouds by specific classes.
If the Override Color check box is selected for a particular class, that class will be shown in its designated colour, overriding other view modes, such as Color From Scanner or Grayscale Intensity Map.
Use for C2C
Users can also choose whether to use the classification for Cloud-to-Cloud (C2C) registration. This can be done by either selecting or deselecting a specific class in the Use for C2C column.
If the class is deselected, it will be excluded from C2C registration. The deselected cloud will not be displayed in Visual Alignment cloud pairs and will not be used for registration.
Adding Classes
To manually change the class of points or fence the portion of the desired point cloud, select the + icon on the class.
WARNING: Undo is not available when classifying point clouds.
The image below shows two Setups that have points in the same area. One has classified the points on the wall as Building, while the other Setup shows them as Created, never Classified.
Fencing this area and clicking the Add icon will move those points to the Building class.
The image below now shows all the points in this area to be on the Building class.
Note: In some cases, the classified point clouds seem to disappear when switching between SiteMap and Bundle Cloud view or Setup view. Selecting Show/Hide Setups twice can refresh the screen, and they will be visible.
Buttons
To run automatic classification on visible point clouds, click the Classification Manager button to open the Classification Manager.
Reload Classes will reset the classes listed in the Classification Viewer to show only the classes that are included in Setups that are not hidden. This is used to limit the number of classes that are visible in the Viewer. In the Classification Manager, all classes are always available.
The Defaults drop-down list includes the following buttons:
Save as Default: Saves a selected combination of Override Color and Use for C2C as default.
Restore Default: Restores the stored defaults.
Reset: Resets to factory settings.
Clicking OK will close the Classification Viewer.
