Grid Scan

This method allows you to scan in Robotic job configuration both with and without image.

Feature Scan

This method involves two independent scanning procedures: scanning with a specific interval within a defined area (Grid Scan) and scanning of the automatically extracted features on an image specific area.

Panorama

Using this option you can take an image or set of images and create scan area.

View

You can see the scanning points of the selected scan project.

Image Scan

Calculates the transformation parameters from image coordinate system to the current coordinate system using at least four control points on the image and after that performs grid scan on one.

Scan Area

This dialog is displayed if you selected Area is selected in Scan Type (the Site Scan dialog).

Set the area for scanning in any of the following ways:

  1. Specify the upper left and lower right points of the area. It can be done by selecting points from the from the map or list . Alternatively, you can measure the necessary points by clicking the Meas button (this will open the Sideshot-Direct dialog).
  2. Specify angles of direction only. In this case, no specifying points is required - turn the instrument telescope to the left border of the area and click Angle Only in the Upper Left group. After that, turn the telescope to the area right border and click Angle Only in the Lower Right group. The angle values will be displayed in the lower part of the dialog.
  3. When measuring points or specifying angles, turning the instrument's laser pointer on (the button) may be helpful.

Click Next to accept the choice and open the Scan Results dialog, or click to close the dialog without changes.


Scan Results

The dialog displays scan results that can be presented in the following views:

Intensity View

For the scanned site, the intensity map of the point cloud data is displayed. Along with capturing points coordinates, the scanner measures the strength of the reflected laser beam. It is represented in the color of the point as intensity.

In the Intensity view, the following controls are available:


2D Map View

To display the top view of the site scan.

You can zoom the image in and out with the and buttons.



Sideshot: Intensity View.

To locate and measure specific points from the intensity image of the scanned site and store them in the current job.

More information about measuring points in optical topo survey.



Site Scan (Shift Scanning)

This dialog guides you through the steps of shift scanning.

Note: The Full Dome (Shift Scan) scanning method allows you to move the instrument from one location to another without having to go through Backsight Setup each time. All of the scans (point cloud fles) can be then post-processed in the specialized software (MAGNET Collage is recommended).

After performing the site scan at your current occupation point, you need to take the following steps before starting the scanning at the next occupation point:

  1. Turn the instrument in the direction of the next occupation. The field Angle displays the chosen direction. Click Next.
  2. Move the instrument to the occupation point. Click Next.
  3. Turn the instrument the direction of the previous occupation.

Note: If Traverse Adjustment was performed in MAGNET Field for a job with site scanning in shift mode the scan stations coordinates recorded on the SD card of scanning device remained unadjusted. Open the Replace Station dialog to update scan stations coordinates on scanning device SD card (to open, click > > > ). To restore original unadjusted scan station coordinates recorded on SD card, open the Restore Station dialog (to open, click > > > ).
