3D Scan manual

Equipment

If you are unsure about setting up the equipment, please ask the staff for help.

Click on the "HP 3D Scan 5" logo.

Set up the camera, projector, callibration board and model.

Try to get sharp lines on the model

by adjusting the focus on the projector.

Like this...

Click on "Setup".

Look at the screen

to adjust the focus and exposure on the camera

Now remove the model

check the calibration scale

Click "Calibrate"

When the calibration is ready, it should look like this.

Now you can remove the calibration board

Click "Scanning"

Select "Background Scan"

Click "Scan Background"

The background should look something like this.

Now choose "Manual Scan Sequence"

Position the model

Check that the focus and exposure are okay.

Click "Scan"...

...and wait.

Now click "Shape Fusion"

Use the mouse to zoom in/out and rotate. Check that it looks okay.

Click "Scanning" again now.

Rotate the model a little bit. (about 30°)

Click "Scan"

Click "Shape Fusion" again and now we can see 2 images of the model in slightly different positions. They need to be aligned.

Click "Align Scans"

First click on the text of the 2nd scan.

Then click on the text of the 1st scan.

wait

The 2 images are now aligned as 1.

Sometimes during a scan the Background Removal doesn't remove all the background.

We can clean this up by clicking on the icon in the "Cleaning" menu.

Draw a square around the unwanted area...

...press "Delete" on the keyboard...

...and it's gone!

Use the mouse to find the best position for removal.

Another way to remove unwanted background is to draw around your model and right-click so that it's selected.

Now click on the black & white icon in the "Cleaning" menu.

This will select the inverse of the model. Press "Delete" on the keyboard.

Rotate and zoom the model to make sure that it's clean.

Click "Scanning" and repeat the scanning part several times.

When you think that you have enough scans, click "Shape Fusion" and it should look something like this.

It's also possible to remove multiple backgrounds at the same time. Just draw around what you would like to keep...

...invert it...

...and delete.

Now it's ready for alignment.

Click on the "eye" icons in the "List of Scans" menu...

...until only the first 3 are visible.

Click "Align Scans"

Now click on the text of the latest visible scan and then click on the text of the previous scan and wait.

Once those scans have aligned, click on the "eye" icon of the next scan and repeat the alignment process until all the scans are aligned.

Sometimes it's difficult to see if 2 scans are aligned properly.

Click on this icon near the top of the screen to view individual scans as separate colours. This is a great help especially when the alignment has gone wrong.

There is also a quicker way to align the scans.

After the scanning stage, instead of going to the "Shape Fusion" you can simply click "Finish Sequence". This automatically aligns all the scans.

But it doesn't always work too well.

Don't worry though. You can still align the scans manually if that doesn't work.

This is an example of when it works well.

And here is the model all aligned with the background cleaned up and now ready for the next step.

Click "Fuse"

Wow!

Rotate it and zoom it to check it's beauty.

Click on "Export"

Save to "File..."

Choose the destination.

And save.

That's it!
