Dfodaro | SHOWCASE | MIRACO PLUS + PMK + 2X Optical Zoom | Marble Sculptures by Venanzo Crocetti and other stuff

Good morning everyone,
today I present you a use case of the new MIRACO PLUS with PMK.
The subject is a beautiful marble sculpture by the twentieth century Italian master Venanzo Crocetti (https://www.museocrocetti.it/ - Many thanks to the president of the Crocetti foundation, and Ioana and Mihai for their availability and courtesy):

The sculptor is one of the masters of Italian sculptural art and in his international artistic activity he has been selected for important commissions. Among these we remember the creation of the so-called “Porta dei Sacramenti”, one of the bronze doors of St. Peter’s basilica in Rome (Door of the Sacraments-St Peter's Basilica-Rome - Walks in Rome (Est. 2001)). At the Hermitage Museum in St. Petersburg a hall is dedicated to his sculptural works (https://hermitagemuseum.org/wps/portal/hermitage/digital-collection/06.+sculpture/57209 - Art works).

As we were saying, the sculpture taken into consideration for testing with the new Miraco scanner is made of marble and represents a “Madonna with Child” (one meter high) and is exhibited in the Crocetti Museum in Rome.
The sculpture is illuminated by spotlights.

The first “challenge” consisted in positioning the targets, markers and bars of the PMK kit on the surface of the work (but I succeeded).

The markers and targets, which are adhesive, could be easily attached (and subsequently removed without damaging the original surface).

The two bars were more complicated to keep in place, but with the help of a double-sided gel tape it was possible to keep them in place (for the entire scanning session) and they too were removed once the scan was completed, leaving the surface untouched.

Once the sculpture preparation was finished, I proceeded with the photogrammetric acquisition session, following the instructions in the user manual, taking 60 photos, and using the angles suggested in the tutorials.

We then proceeded with the processing and in the end here is the result:

Next, after removing the two bars, once the global marker reference was loaded, I proceeded to scan, using single shot mode.

Subsequently, once the global marker reference was loaded, I proceeded to perform the scan, using the single shot mode (410 frames):

After finishing the acquisition, I proceeded to perform the fusion operation and then the meshing:

Of course, some editing (using RevoScan and MeshMixer) was necessary to get the finished 3D model:

The result is remarkable, the chisel work (made with a special chisel with teeth called “gradina”)


(image below, indicated with yellow arrows) of the surface is clearly visible as well as the measuring points (red arrows) used by the sculptor as dimensional references (Pointing machine - Wikipedia).

Post Scriptum coming soon here other scans made with MIRACO PLUS on other sculptures of the museum

Good morning everyone,
Today I will show you more 3D scans of marble sculptures by master Crocetti, again on display in the Museum named after him.

The Miraco Plus scanner allows you to capture using the implemented optical zoom, which allows you to capture more detail.

Having had the opportunity to test this option of MIRACO PLUS on these beautiful sculptures, I took advantage of it and below I show you the results.

This is the first marble sculpture on which I tested optical zoom:

I proceeded in this way:
First step:

  • Far mode, IR Optical Zoom 2X, single shot mode;
    To capture the whole sculpture.

I proceeded in this way:
Second step:
Resume scan

  • Near mode;
  • IR Optical Zoom 2X;
  • Single shot.
    To re-capture the entire sculpture.

Finally, I processed the Raw data, fusing in Standard mode at 0.2 mm.

After that I created meshing

Below is the result I show you with the details displayed in Meshlab (and photos):
