Identify common points

To identify common points, follow the steps below:

1. Right-click the scan to be registered and select Show BubbleView OR alternatively drag and drop the scan node into the 3D window. The BubbleView will load for the selected scan and the Tools toolbar will become available at the top of the interface. Anything on a flat surface can be used as a target as long as it can be seen in both scans being registered together. Corners of signs or small marks on walls traditionally make good targets.

2. Load the 3D points belonging to a scan by right-clicking on the scan and selecting Load Points.

3. Navigate round the BubbleView to the first point to be picked.

4. Select the Pick Targets button from the BubbleView toolbar and select the point with the left mouse button. This brings up a small magnified target identification area.

   

5. Alternatively, targets can also be picked in the 3D window. This is useful for registering mobile scan data (such as .pts or .dp) which will not produce a BubbleView.

6. After picking the target, the Identify Target window appears. Type in the name of the target (example, T1) and select OK. Identified targets appear as yellow crosses in the BubbleView and as black target icons under the scan node in the Registration tab.

   

7. Repeat this process for other targets in the scan and also the same targets in the other scans to be registered.

8. After the targets have been identified in both scans, right-click the group node and select Register All. Depending on the quality and accuracy of the picked targets, this will place the scans in roughly the correct position. This function only applies to the parent group, it does not apply to any child groups.
