Scanning skulls to forensics with PPT GUI and Meshlab, the evolution of methodology


Following with the develop of a protocol to formalize the use of PPT GUI on forensics science, we are simplifying and making more accurate the obtaining of 3D skull using photos.


Instead to use Blender to joint the parts of the skull, the entire work is made in Meshlab.

If the artist wanna use the skull to do a reconstruction, he/she can import it on Blender with tranquility.

The advantage of this methodology is that you can reconstruct the entire skull using the best part of two or more sequence of photos.






The work is being developed by Cícero Moraes (me), Dr. Paulo Miamoto and other researchers from Brazil and Czech Republic.

Melani, head of the Forensic Anthropology and Dentistry Laboratory (OFLAB/FOUSP) - Faculty of Dentistry, University of São Paulo, São Paulo, Brazil; Mikoláš Jurda - Laboratory of Morphology and Forensic Anthropology - Faculty of Sciences, Masaryk University, Brno, Czech Republic.

In order to reveal the limitations of the PPT GUI, a test of scanning was made in bad conditions for this type of acquiring data.


A skull (with reflecting-light) was photographed in a room of low lights an a simple camera, without isolate the scenario.

Fortunately the result was good, at least to make a forensic facial reconstruction.

The test was made thanks to the help of Prof. Dr. Joel A. Sousa and Lis Caroline.

  1. Hi.
    My name is Luciano and I'm from Naples. I read your blog since years and I want congratulate for your work.
    It would be useful to know more infoes on the blender part of the texturing.

    Cheers

  2. Hi Luciano,
    sorry for the late answer. Maybe Cicero can write something about it in one of the next post...
