Individual assignment: 3D scan an object#

We decided to use the 3D scanner to scan this tree stump that was outside the lab.

This was our 3D scanner which was portable and could do a lot of onboard processing.

This is a model named 3D scanner. It’s an Artec 3D scanner and the model name is Artec Leo.

We go outside and click new project on the 3D scanner.

We had to adjust the range on the 3D scanner and we set it to about one meter.

While scanning, you can see the green patches in the image on the display show that that area has been captured, while the red patches show that the area could not be captured as well, so we have to get more green overall.

While scanning, green patches show captured areas and red patches show areas that need more scanning

Given this is an expensive higher end scanner, it seems to render a really good view of the scan on the scanner display itself.

I saved the scan on the scanner and then now we have to import it into the Artec software for post processing.

In Artec Studio software, we click connect to Leo.

Then we select our particular Leo which is connected to the same network.

Then we select my file.

Then we select my file

It was about a 2 gigabyte file so it took a while to load.

Now to cut off the extra bits of land that we don’t need, we tried the lasso selection tool.

We selected the base with the lasso and erased it.

Then we got this.

Now for post processing, we first have to run registration in the tool section to be able to do post processing on it.

We tried some outlier removal to remove the extra bits, but it didn’t really seem to help.

Then we run the Fusion tool to convert the point cloud into a mesh that makes it easier to edit and then later print as well.

We set the mesh resolution to 0.1mm.

We set the mesh resolution to 0.1mm

This is what we got. As you can see, there are some holes in here that we need to fill. Otherwise it’s not watertight and not printable.

The mesh has some holes that need to be filled to make it watertight and printable

So we used the fill holes operation, but this took forever, and since I did not have time in the lab, I had to cancel this.

We used the fill holes operation but it took too long and had to be cancelled

Then to reduce the file size, we ran the isotropic remesh.

Running isotropic remesh to reduce file size

Used a resolution of about 2mm for the isotropic remesh just for experimental purposes.

This is what I got at the end of it. It’s a much smaller file.

The final result after isotropic remesh, a much smaller file

Then I exported it as a mesh.

And I exported it to an STL file.
