Trimble Novapoint Help
This is the dialog where you import and triangulate the scanner data for your tunnel.
The following information must be given for a scanner data set:
A unique Number in the project.
A name describing the data set. User-defined or auto-created when selecting new files.
The active status. If active, the dataset is used in various calculation and visualization tasks.
This section displays the selected point files and their associated scripts.
You can import a point cloud from the “New file” tool button.
The script is used as a preprocessing step to format the text file to extract only the valid point set data.
You can save the modified point cloud data to a new file by clicking the “Save All Modified Point Files” button.
In this section you can:
Set up the result file for the triangulation. The result will be persisted along with the project.
Specify the vertical offset for the tunnel reference line. This reference line is used as the center of a cylinder for triangulation of the scanner data based on cylinder coordinates.
Filter triangles above a given size
Perform the triangulation of the point cloud. The triangulation exists only in memory until the user actively saves the entire project.
This section displays where the point cloud is located along the road.
For new data sets, this value is set automatically when the point set is triangulated.
The values may be overwritten by the user.
This section allows you to set up the drawing properties of a given point cloud.
Separate colors can be used for the points (input) and the section made through the triangulated tunnel body.
Use the Chainage Interval to decide how many of the scanner data points in front and back of the section plane to include in the drawing of the cross-section viewer. Half of the chainage interval is in front of the actual chainage value in the viewer and half of the chainage interval is behind.
Click on OK to save the data from this dialog to the tunnel model shown in the Define Tunnel Profile Geometry dialog and close the dialog.
Click on Apply to just save the data from this dialog to the tunnel model without closing the dialog.
Click on Close to shut down this dialog without saving the data.
