Software 3D scanner. Creating 3d models "with my hands" ; )

Just upload 2 photos and my program will create a 3D object ready for printing. Amazing STL Creator 9: 3D Scanner
You can download the app from cults3d.com/en...

Cool results! What algorithm do you use?
Could you please share a paper if it's public?

Thank you for your interest!
The app uses the principle of stereophotos. The program selects a small round window in one photo, then looks for the same window in another photo. And scans with this window over the entire photo. And we get a displacement map. And I also use cellular automaton technologies so that neighboring pixels interact and, in general, the search speeds up.
All algorithms are simple and logical, there are no scientific tricks to study papers, it's just a programmer's work)

@@Posmetyev thanks!
If you're interested, there are monocular depth estimation approaches, there the neural network predicts the depth over the image just from single photo. Of course, it's relative units, but still impressive. I'd like to be connected on LinkedIn, but I couldn't find you there. If you are there and there's a chance to be connected, I'm Aleksandr Rybnikov from Berlin, it's the unique combination there

Hey there, I actually bought the program and been playing with it for the past couple days. Can't seem to get the result at all. When I load the file into Cura, it just look like a mountain range and spikes etc, nothing resembling my face at all. What am I doing wrong?

Dear Ray Z! Thank you for downloading the program!
Usually these 4 things help to get good scans with the program:
1) Here are 4 sample pairs of photos. Please try to load them into the program to make sure that the program works and creates good models
drive.google.com/file/d/14bQn_mxSkTIw3Jl3Tgh-aZcu78TXxC4l/view?usp=share_link
2) I recommend first viewing the resulting 3d models in a color (not black and white) viewer, for example 3dviewer.net/
Please drag both OBJ+MTL resulting files to the viewer, and you will see a colored object. The colored model allows to immediately understand if there are problems with scanning the background or the object itself, and you will see what needs to be corrected when taking a photo
3) The most common mistake is that two photographing points are too far apart. The distance between the left and right shooting points should be about 5-8 cm when shooting an object at a distance of 50-100 cm. Sometimes the problem may be in the object itself.
4) If the object is shiny, transparent or monotonous, the photos do not contain information to restore the corresponding parts of the 3d model. In such cases, it is necessary to "texture" the bad areas on the object: sprinkle it with flour, or randomly color it with mate acrylic paint, or stick paper tapes with a pattern, or put a lot of small pieces of paper 1x1 mm in size on it.
if you send me your photos to [e-mail] I can analyze them more detailed and find ways to get good scans.
