Ortho Project : Scan (step 2)

The 3D scan will be a real challenge : the goal is to get the best possible scan of my jaw, because at the end it will impact the movement of my teeth. At this scale, millimeter counts.

At first, I tried to look for “fab lab” around Paris where I could eventually find a 3D scanner to use. Dead end, either the lab were definitively closed or there were too far from my house or work.

I found a company on internet, in Paris also, that realized 3D scan with professional scanner : the quote for my jaw was around 200€. No way ! I had to find something cheaper. (I was not even sure of the result at this time, and didn’t want to engage to many money)

Finally, parsing the infinite internet, I found solutions to do it myself. Why not, I really enjoy do things only by myself !
I discovered the photogrammetry : a technique that transforms multiples images of an object into a 3d object. Nice, that’s what I need !
First I tried mobile app on my phone, but the result was quite cheap : a smartphone cannot process so many data.
But then, I found Meshroom ! #holygraal

Meshroom is an open source photogrammetry software, almost usable by everyone.

The first tries I did were not very conclusive, but I look for advices to improve the scan, and some French guys on Youtube give me the perfect trick : dots !
As Meshroom will try to match different pictures from my model, I needed to help him with points that it can identify and recognize.
It works like a charm (after 2 hours of compute, with a hundred picture), and I get a very nice 3d model with only my smartphone as a camera and a computer !

Awesome model, with no disturbances

My 3D model is there, the first challenge is a success !

Next step, the manipulation of the 3D model.
