This is a printable version of the sample scanned head you get with the 3 phase software. But getting it to a printable object is no mean feat it seems. I will try to describe the procedure here

Here's my Processing sketch to interface with the Kinect and capture the depth data and render it as a solid STL file. I've included controls to adjust two thresholds - near and far. This allows you to set up a "Han Solo in carbonite" type effect.

I am not going to hold your hand through setting up Processing and this write up is In Progress, so if you get frustrated, realize that this might not be for you yet. Until I find a way to streamline posting a standalone application that works (currently it doesn't), this is still only for the persistent.

Until Microsoft publishes the code for their KinectFusion project, this is the best I could do to get a directly printable object without messing around in Blender or MeshLab. It's also my first serious coding effort, so forgive any inelegant code. Yes, the STL files are large (15mb) and the detail is hard for the CupCake to print, but it has the outreach potential for people new to 3D printers to create a unique, personalized object by just posing. Before you ask, the STL doesn't seem to take any less time in skeinforge if you use Blender to remove all duplicate vertices first, so I don't bother.

A hangable 3D scanner based on the kinect, arduino, and a stepper motor.

Not working yet, but figured I'd put it up so I could get critiques and suggestions as I work.

The code base is currently in progress, will be borrowing heavily from Kyle McDonald's work for Makerbot, of course. Am sketching it up at the moment, unsure whether I want to do it in Java (very familiar) or Cpp through OF.

v0.2 (files up, not tested or 100%) Defined solution for hub. 4 piece design with bearings.

v0.15 Physical testing and modification of outerJoint and innerJoint. These include adding radial support screws, modified teeth, and refined build methods. The failed code is retained in the build methods with explanation, just for the hell of it.

v0.1 Framework of object and base line openSCAD file. Only parts printed/tested so far are arm joints.

360 degree 3D laser scanner.

Still a work in progress, but I wanted to post what I have so far.

The latest version can be found at github.com/tbuser/spinscan_turntable

I'm also working on software at github.com/tbuser/spinscan

Structure from motion is a class of algorithms that take information about point correspondences between images and use them to reconstruct 3D scenes. While some pretty serious math is involved, no specialist hardware is required aside from a camera.

We've seen lots of structure from motion based 3D scanning solutions already this year, the best known being my3dscanner.com/, but all of them are closed source. This is hard to deal with when I see cool things like Qi Pan's ProFORMA software (http://www.youtube.com/watch?v=vEOmzjImsVc&fmt=22) but can't use them or look at how they work. There's been plenty of good open source innovation in laser based 3D scanners, but very little on the software side of scanning, which kind of surprises me given that software is usually the area that people think of as conducive to an open source approach.

So for my computational photography final project last semester I set out to make an open source SFM scanner in Matlab, since a lot of toolkits were already available to do the heavy math part. Unfortunately I won't have much time to work on it this summer, so I decided to release the code now to see if anyone could do anything with it.

The program starts with either user input images or input from a webcam, extracts feature points using David Lowe's SIFT, attempts to remove outliers using the MAPSAC algorithm from Philip Torr's toolkit, then uses Vincent Rabaud's toolkit to reconstruct the 3D positions of the points. From there Liugi Giaccari's implementation of the Crust algorithm is used to find a surface mesh automatically, and a function by Andreas Richter I found on the Matlab file exchange to export an STL file. The end result is that you can (theoretically) go from photo capture to STL output without any user intervention. In practice you might be better off exporting the point cloud and meshing it with Meshlab or some other program.

As of now I have only written a function to extract structure from 2 images using the normalized 8 point algorithm. I think this might require a stereo camera setup, which you might be able to approximate using just one webcam. More importantly, SIFT is not a very good detector for getting dense sets of features, and 2 images will not give you much to work with, so results as of now will be poor to unrecognizable. Fortunately all the code is pretty modular, so switching in a new feature detector or making other modifications should work fine after transposing a matrix or changing some variables.

Vincent's toolbox can use quite a few different methods, most of which are much better than the 8 point algorithm, but it needs either calibration data or more than 2 input images. Implementing affine and metric upgrades would be even better. I'm hopeful that this project will progress to the point where it is possible to make use of these methods, and I'll try to answer any questions anyone trying to add to what's there now might have.

If you're interested in more detail on how everything was done you can read my final project report, attached below.

This is a laser scanning system that I designed to use with DAVID 3D Scanner software. I have yet to buy the software, but the free version really lets you try out everything before you buy...you can at least take some high resolution screenshots of your scans. You can save low resolution files and use meshlab to assemble them.

More info at: david-laserscanner.com/

The first scanner I designed was complicated and used gears and a stepper motor, this one works much better. It's cheaper, requires no electricity to move and has less parts. It even tells you when it's done scanning!

It uses a Taylor kitchen timer, this is a mechanical wound timer that you can purchase at Target, for about $3 PN: 5833-21

When combined with custom maker bot parts, two M3 screws/nuts and a red focusable line laser you have a nice smoothly sweeping laser system.

This is a tool for taking pictures for my3dscanner. This thing consists of rails and a stand. Print 6 rails for half circle and 12 for 360 degrees. Assemble the rails like those of children's wooden railroad, insert the stand into the groove, attach the camera to the top of the stand. Take a picture, and slide the stand with the camera to next position. My3dscanner recommends 30 pictures for 180 degree project so i have made ticks on the rail for easier positioning.

Disclaimer: this is my first project and this thing is probably not very printable just yet. I have some ideas how to make the stand more printable by breaking it into parts. I welcome all comments and advice.

This is the result of being 3D-scanned with Creaforms Body Digitizer Gemini system. The scanning took about 30 seconds total, and then around 15 minutes for cleaning the mesh.

This is just an experiment I made with my iPhone 4 to make a 3D scan of a remote object and then to make a 3D model. Now I am trying to figure out what to do with the 3D model. How to integrate it into something to make a useful thing? It's a big mesh so I guess only 3D printing will work.

This is a little Dragon model which we scanned and printed in a test on how fast we could go from real object to printed object with our automated scanner and a mendel.
The full time needed was 5 hours from real object to copy.

The object is around 6x4x4cm and was printed in white PLA with a layer height of 0.2mm.

This is a small project to mount a Kinect on a standard Camera tripod.

This is a steppermotor carriage for a laserpointer. You can mount it to a m8 bar.
It was designed to move the laserpointer of a 3D scanner very slowly but continuously.

The steppermotor has a step angle of 0.9 °. The controller has a substepping of 16, so one complete rotation is divided into 6400 steps.

Now it is possible to scan with a resolution of 1280x1024 with an almost perfect result!

You can drink as much coffee as you like - it will not affect your 3D scans :-)

This is a modification of the MakerScanner v0.3 scanner for the BDL220S Black & Decker Laser Line Level with Wall Mount.

blackanddecker.com/power-tools/BDL220S.aspx

It's designed to use the wall mount's existing magnetic rotational bearing. I chose this as it was one of the cheapest laser line levels at my local hardware store (this is carried at Lowe's and Ace Hardware as far as I could tell online) Because of the integration of the wall mount, you get a very solid, very smoothly rotating scanner.

The BDL220S base unit is removeable for transport and use as intended. If you'd like to still be able to use the wall mount, Black and Decker sells extra base units from their parts replacement center: blackanddeckerservicenet.com/Products/PartDetails.aspx?partid=242704

A group of us at the Berks CoLab hackerspace berkscolab.org decided we wanted to figure out how to do 3D scanning and this is the best result we've had so far.

It was created with the Makerscanner software wiki.makerbot.com/makerscanner by hand (we didn't print out the Makerscanner mount yet) using a laser line level and a 1.3 megapixel Creative webcam.

Face Scan using the Makerbot 3D Scanner and a new PS3 EYE

more instructions soon to come on the wiki.makerbot.com/cyclops page! (best lighting conditions, etc..)

The Makerbot 3D Scanner kit is a MOUNT made fit for a pico projector, webcam, and an (optional) iphone/ipod.

for more details on the 3D Scanner, and all of the components needed to take three-dimensional scans, please visit the 3D Scanner wiki page:

Put your PS3 Eye on a tripod! Why not?

Starting with the CameraHolder.stl from abarry's MakerScanner 0.3 (thing:3946), I wrote a goofy little OpenSCAD script to chop off some of the scanner-specific parts, thicken the base, and cut out space for a standard tripod 1/4"-20 hex nut and bolt.

License is GPL based on abarry's MakerScanner license and use of Catarina Mota's shapes.scad (http://www.thingiverse.com/download:11183).

This is a derivative of the Makerscanner thingiverse.com/thing:3946. This has a quick and dirty mount to get your logitech camera to sit firmly in the makerscanner.

The MakerScanner is a completely open source 3D-scanner and the perfect complement to a MakerBot or other 3D printer. Every one of the scanner's plastic parts can be printed on a MakerBot or other 3D printer!

Update: I've added parts with slightly different tolerances for printing on the Stratasys 3D printers.

This is my face. We used the 3d scanner described here: thingiverse.com/thing:1491 and here: abarry.org/stereo to scan and then print the face.

Update -- just printed a new version upside down for much better print resolution!

We are developing a 3d scanner based on parts printed from a makerbot. These files show the printed parts, put together with a logitech camera, a laser, and a mirror mounted on a galvanometer. The basic idea along with our first implementation is described here: abarry.org/stereo

We are developing the software using a microchip PIC to drive the mirror, along with software to obtain point clouds and meshlab to mesh the point cloud. There is a long way to go with the software, but at least we have some nice printed hardware to get the data. UPDATE: new scans -- we've added a screenshot of a scanned artichoke!

Support to hold a PS3 Eye horizontally.
This is a first draft, hopefully there will be an improved second draft,.. soon ;)

This is my first cut of a 3D turntable scanner that can be printed on a cupcake/reprap. It is by no means finished but it is a start.

It has a turntable driven by a motor ( a size I had in my 'bits' box ) and mounts for a camera and the laser line drawer.

It needs heaps more work but I thought I'd put the first cut into the thingiverse and see what people came up with

The blender file of the complete device is included in the tar gzip file. I have not uploaded all the stl files individually , grab the zip if you want them all.

To build it you will need a 608 bearing , 5mm (or 3/8 ) rod , some M4-20 bolts , a motor , webcam , laser pointer and possibly a PHD in quantum physics :P

There is no software yet but this

sjbaker.org/wiki/index.php?title=A_Simple_3D_Scanner

looks like a good start; combined with an arduino to index the wheel and some scripting this could be a automatic scanner.
