Man Acquisition

Acquisitions

Acquiring data from the scanner and create a virtual 3D representation of an object is the primary function of the OpticalRevEng Dental software.

If you're working using the Step-By-Step Wizard you can look at Wizard Acquisition page.

In a Structured Project outside of the wizard you have 3 way to acquire data from the scanner.

Simple

This is the most simple way to acquire data, and the one you'll use the most. You just have to:

1. Put the object inside the scanner over the appropiate model holder
2. Select the object you want to scan in the Project Tree
3. Click the Acquisition button on the Main Toolbar

The scanner will then acquire the object inside with the strategy of the selected element and update the status of the Project Tree

Multi-Die

If you want to acquire multiple dies in one scan using the multi-die support holder yo have to:

1. Select from the Project Tree all the dies you want to scan
2. Click the Multi-Die Acquisition button that will appear on the Main Toolbar as soon as at least 2 dies are selected in the Project Tree
3. Put the dies in the support as the software will show on the Top Right window and put the Multi-Die support inside the scanner
4. Click the Start Acquisition button

The scanner will acquire the data, identify every single die and update the status of the Project Tree

Single

If you need to acquire a single 3d image and not a 360° object recostruction (for test or to acquire a big articulation in a small scanner) you can:

1. Put the object inside the scanner in the best way possible
2. Use the Single Acquisition tool

The software will do a single acquisition without moving the manipulator

Integration

After you've acquired an object from the scanner, you may want to add further information from the startign scan. For example part of the object may be missing due to shadows or because the acquisition strategy has not covered a specific point of view that you need.

For integrate additional information you can use the Integrate Acquisition button on the Main Toolbar. This will start the Integration Mode that gives you 3 different integration tools. You can pass from one tool to the other all the times you want. When you've finished you can confirm the modification with the Apply button or discard everything with the Cancel button.

You can add all the additional acquisition you want but adding to much data can slow down the project and increase the project disk size

Single

The single integration mode let you add information from a specific point of view. To add information you just need to:

1. Rotate the 3D view in a way that the screen show exactly the part you want to integrate
2. Click the Start Integration button

If the last added acquisition is not good, not needed or has some problem you can remove it with the Undo button.

If the object is not in the original scannin position the software can not integrate the information correctly. You can try to fix this using the Calc Integration Position Button

Custom

In custom mode, instead to scan one position at a time, you can create a personalized sequence of position and then let the scanner do all the acquisitions togheter.
To add a position you have to:

1. Rotate the 3D view in a way that the screen show exactly the part you want to integrate
2. Click the Add Position button

To remove a position you have to:

1. Select the position from the list
2. Click the Remove Position button

To start the scan you have to click the Start Integration button

Full

The full integration is the simplies. You select how much positions you want to take and how much you want to tilt the model.
Then when you click the Start Integration button the scanner will tilt the model and do a 360° acquisition using the number of positions selected.

Change Strategy

When the Project Tree is created the software will select a specific strategy for every element in the project trying to maximize the scan quality and saving space. If you need to change the strategy for a specific element of the project you can:

1. Right click on the element in the project tree
2. Select Change Strategy
3. Select the new strategy from the dropdown menù

If you scan again the object you'll see that the scanner will use the new strategy instead of the old one

Now that you know how to acquire data from the scanner you can return to the Main Page or continue to the Data Editing page
