When you acquire more than one object from the scanner they will be in different positions. To correctly work with the scanner data you need to bring all the Acquisition to the same position reference. 
 
  
For this you first need to identify an Acquisition that will be used as a reference for all the others. In the '''Structured Projects''' this is done automatically by the software.

There are two options available during the manual aligment:

This can create problems if the common part between the two objects is really small. With '''Fine Aligment''' enabled the software will move the moving object not more than 0.1mm
 
# '''Ignore Normals''' : The objects have an inside and an outside. When the software search for an alignment it refuse to align the inside of one object with the outouside of the other.

Alignment

When more than one object is acquired by the scanner, the position of each item is unrelated to the position of the others. In order to correctly work with the scanned data, all the Acquisitions need to be located in the same reference system.

Firstly, the user has to identify an Acquisition that will be used as reference for all the others. In the Structured Projects, the software automatically carries out this procedure.

Every time a new information is acquired, it is necessary to align the new data to the Reference Acquisition or to another acquisition already aligned to the rest of the project

Every acquired information will have a specific Reference Acquisition. The Project Tree will show this relation, every child will be aligned to its parent node in the tree.

Direct Alignment

OpticalRevEng Dental can automatically align the Acquisitions:

  1. Select from the Project Tree the element that has to be aligned to the rest of the project
  2. Click the Alignment Button in the Main Toolbar

The software will choose the reference, it will analyze the selected acquisition and the reference and it will identify the correct position of the selected item with respect to the reference.
If no alignment can be identified by the software, a Manual Alignment will start.

Manual Alignment

The manual alignment starts every time the software can not perform a Direct Alignment. The user can also acceed this tool by holding Key shift.png when clicking the Alignment Button in the Main Toolbar

Interface

The picture here below shows the interface of the manual alignment:

Dental 2 5 manualAlignment.jpg

There are 4 different areas in this screen:

  • On the top left is displayed the reference object, which gives the reference position for all the project data
  • On the top right is shown the moving object, that has to be moved from its current position and placed in the same reference system of all the other project data
  • On the bottom are displayed both objects, so that the user can check the current position of the moving object
  • On the bottom right some options and a Numeric Report are available

Procedure

To manually align the elements:

  1. Place both the reference object and the moving object in the same point of view, until the parts in common are visible
  2. Click on the same point on both the objects
  3. Check in the 3D view below, if the position is more or less correct (it's not necessary, at this stage, to find the perfect position)
  4. Click the Best Fit button on the right

If the two objects have enough points in common, the software will find the best alignment between them. Visually check the alignment on the bottom 3D View or by reading the values in the Numeric Report.

If the alignment is correct, click Ok to confirm the new position of the moving object.

Otherwise, click the Reset button and restart the alignment.

Options

There are two options available during the manual aligment:

  1. Fine Alignment : usually Best Fit moves the object up to 1mm closer to the reference. If the parts in common between the two objects are really small ,use Fine Aligment to move the object not more than 0.1mm closer to the reference
  2. Ignore Normals : allows the user to align the internal part of an object to the external part of another, and viceversa.
