Locating Reflectors

Source file: locate-reflectors.htm

The Locate Reflectors tool will find and flag any reflectors found in a scan. Reflectors are usually small, highly reflective regions, similar to standard survey prisms.

1. Select a scan or a group of points within a scan.
• When a group of points is selected, the tool will locate a single reflector within the selection.
• Otherwise the tool will locate multiple reflectors in the selected scan.
2.  Right-click on a scan point in a view window for the context menu and hover over Query, then from the list select Locate Reflectors in <scan name>.

   

   

3. Select the number of reflectors to find by entering a number or moving the slider.

4. Select De-emphasise large bright regions to help filter out other reflective objects, such as road signs.

5. Click OK or Apply.

   The reflector locations will be indicated on the scan with green crosses. They will be numbered, annotated and placed in the survey container.

Note:   As locating reflectors uses the topology of the scan, make sure the scan is not filtered for best results.

Tip:   Use reflector locations in conjunction with matching point pairs to locate scans.
