Alignment

Alinhamento

Quando mais de um objeto é escaneado pelo escaner, a posição de cada item não está relacionada com a posição dos outros. A fim de trabalhar corretamente com os dados escaneados, todas as aquisições precisam estar localizados no mesmo sistema de referência.

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

Toda a informação adquirida terá uma específica 'Referência de Aquisição' . O Projeto Arvore irá mostrar esta relação, cada filho será alinhado ao seu nó pai na árvore.

Alinhamento Direto

OpticalRevEng Dental can automatically align the Acquisitions:

1. Selecione pela árvore de projeto o elemento que tem de ser alinhado com o resto do projeto
2. Clique o Botão Alinhamento na Principal Barra de Ferramentas

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.

Alinhamento Manual

O alinhamento manual começa cada vez que o software não pode completar um 'Alinhamento Direto' ou segurando o botão ao clicar no Botão de Alinhamento no Principal Barra de ferramentas

Interface

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

Existem 4 áreas diferentes nesta tela:

• 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

Procedimento

Para alinhar manualmente os elementos:

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.

Opções

Existem duas opções disponíveis durante o Alinhamento manual:

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.
