Re: Kscan3d Full Version
Hedda Stachowiak
Recently I used Kinect to 3D scan a human model; Results were nice but there were all kinds of artifacts in geometry and color texture. I discovered that Blender is a nice tool for fixing such artifacts, as you can see from this video that presents my end result and work process in Blender:
This 3D scan was obtained with Skanect software by going a full circle around the model while filming her with Kinect. Skanect gives a simple interface for 3D scanning with Kinect, creating a watertight mesh, and importing textured 3D models. The downside is that it costs $129.
You can get started with 3D scanning using free software, to see if Kinect scanning works for you. Free scanning software has less integrated post-processing features and getting a textured mesh out of them requires more work.
Another free option is Kinect Fusion of Microsoft Kinect SDK:

If you want a detailed overview about fixing 3D scan artifacts, check out these great tutorials by Infinite-realities:

In the videos they use Zbrush and other software, but you can do same operations in Blender as well.
I was wondering if anyone here had any insight into 3D scanning. Ive looked at some consumer products that look very pricey and have been looking at some homemade solutions too but they seem quite time consuming and inaccurate. I would really like to have 3D scanner with my ultimaker it would make modifying/upgrading existing things alot easier.
I've seen people use ReconstructMe. It's actually the only thing that I've seen being used with results. But it's limited to the resolution of the Kinect. So it can only scan things that are about "human sized"
yeah Ive looked at reconstruct me it looks like a better solution than nothing especially since you can pick up a kineckt for around 50 euros in the local classifieds. i think i might give it a try. Otherwise I think i have to wait until some new sort of technology comes or some new sort of cash flow comes!
Reconstructme worked well, when I had hardware it was OK with. Unfortunately it was completely incompatible with my two laptops. KScan3D didn't perform as well, but it was more hardware friendly -- as its just come out I'm sure it has been refined a bit.
The sensor Im using is a Primesense Carmine 1.09 with Skanect software and it delivers me printable objects within a few minutes. Skanect is great since it has finishing tools inside like making the scan watertight, plane cuts to remove background noise, etc etc. Also you can export full color scans with this and send it off to your full color 3d printing service.
In order to get an even higher resolution output from the sensor Ive put a +2.5 strong reading glasses on top of it, the amount of detail is crazy with this. This also works for the Kinect but still doesn't deliver the same results as with the carmine with glasses.
The software itself works best with a high end video card with lots of CUDA cores on it, but it's not fully needed. Since the last version (1.3) there is also the option to use CPU instead of GPU to reconstruct the scan. You won't get a good feedback during scanning, but it will record and reconstruct it on a slower pace later on.
I bought the Kinect solely to do 3D scanning. I spent a lot of time researching how this could be done before ending up with the Kinect. There are several Youtube videos explaining how to 3D scan with various types of technologies.
Photogrammetry, reconstructing 3D models from photos of objects, seemed the most easy way forward. 3DF Zephyr offers a free photogrammetry software (3DF Zephyr Free), with some limitations. To get photogrammetry to work you need to take good pictures of the model in good lighting conditions, preferably using a SLR camera with lots of megapixels. As an amateur wanting to try it out I downloaded a package of demo images from 3DF Zephyr and also went forward using my old iPhone 5s.
Even with my phone I managed to create 3D models. The free version is limited to only 50 photos, and this really takes away detail. There was no easy way to convert the resulting 3D model to an .stl file and print it. Furthermore, the whole process of cleaning up pictures and stitching them together was tedious and not very intuitive or simple.
I quickly found out that the connector was not the typical USB connector I could connect into my PC. I found that a specific Kinect adapter was needed, but this product was discontinued from Microsoft. Another option was to order a Chinese clone on Ebay, but this would set the project on hold for a month.
I asked my girlfriend to come into the room where I had the Kinect on a table on top of a small stack of books. She turned around clockwise while the Kinect scanned multiple positions. Cleaning up the various point clouds were fairly easy as you could select multiple scans and delete unwanted points in groups, next converting the clouds to a mesh and then finally export to .stl format for 3D printing.
When I got to the point where I actually had the scanned model and could 3D print it I wanted to do more. In Meshmixer there are a lot of possibilities to be creative with .stl files, meshes and polygons.
I wanted to create an artistic representation of the model and aimed for a voronoi tessellation type of pattern. The scanned mesh model had a lot of detail and small polygons so I needed to reduce the polygon size in certain areas, and play around with various brushes and tweaking settings as I went on.
This was my first time using Meshmixer and I was blown away with what I created. The figure now had a beautiful pattern while maintaining the human form and shape of the belly. What I found fascinating was the simplicity of the form and the complexity in the pattern surrounding it. The mesh was detailed and at the same time smooth.
3D printing these now complex shapes needed some careful tuning and checking. Using the Cura slicer I went over the layer views several times tweaking the settings to make it right. The models showed plenty of overhangs due to the patterns, but printing these with supports were not an option. Removing supports on a model like this would be close to impossible.

The SR300 is integrated into various devices by third parties. For 3D Scanning, the most important one is the 3D Systems Sense 2 (Review) pictured above. This version is really intended for 3D scanning and comes in a housing that makes it easy to hold it in upright position. It works with the great (and free) Sense for RealSense software.
If you want a depth sensor to make 3D Scans on a Windows 10 machine, the RealSense SR300 is a great option. Because of the with free, versatile software I currently advice to get the 3D Systems Sense 2 instead of the slightly cheaper webcam-style alternatives.
