Picture of Multiple Raspberry PI 3D Scanner

UPDATE: Check out step 8 for the latest version of my scanner and a download link for the python scripts.

Hi,

I am a big Arduino and Raspberry PI fan and also love 3D printing. I wanted to be able to make a 3d model of my kids and started investigating how to build a 3d scanner. I found a lot of solutions out there, but the problem with most of them is that the subject would have to sit still for a while... well I think it would be easier for me to invent a spaceship that can fly to mars then inventing a solution for my 2-year old son to sit still :-( So none of those solutions where going to work.

I knew I had to come up with a way to instantly take many images at the same time. So I first started to research what cheap digital cameras exists. If I could find a cheap model, I probably could make an automated trigger system using arduinos. But then I would have all the images on many separate SD cards and I was not able to find a cheap good digital camera.

Then I noticed the Raspberry PI and PI camera combination. A "fairly" affordable module, that already is ethernet connected, so I could do the triggering of the cameras using the network and an easy way to download all the images to a centralized place. So my Project (and investment) started.

I bought for this project:
- 40 Raspberry Pies for this project and 40 PI cameras.
- 40 8Gb SD cards
- 1 single 60A 5v power supply to power all the raspberry Pies
- Led Strips and a powerful 12v power supply to power them on

As I am an impatient person I did not build the whole setup at once, I started of with 12 cameras, and was already seriously impressed with the results. So you DO NOT need 40 cameras, especially not if you just want to catch just the front of a persons face.

Here a result output:

UPDATE:
I have included a photo of Britt (the model in the video) being printed in full color by shapeways.

UPDATE2:

I finally was able to make a scan of my little son Hugo (2years old). It was made using 47 Raspberries and using my new softboxes with permanent lights. This allows me to shoot the images with no shadow. Can't wait to receive the printed model from shapeways :-)

Hi Richard,

I made the network cables using 4 wires and sparing the other 4 wires for power. I managed to power up the pi this way but the pi cannot connect to network although the network cable works when I don't plug in the power wires. I am using the AC to DC convertor power source of desktops.

Any guess what the problem might be?

Thanks,

Azadeh

Do you control your raspberry pi's with a laptop or by another pi?
the_anykey (author)  Csalway2 months ago
you can do either. I have written windows software to easy control everything and manage the preview and downloading. You can find it on my website in the download section. www.pi3dscan.com
Ok thanks

This is terrifc higher performance solution for a very low budget price.

My first thought was the

PiScan can make a 1:1 scale 3D model of a face in about an hour.

Use this a mould to make a latex mask.

Paint it up in line with the images and you can make a look-alike in a few hours.

Hi Richard,

It is a great and very appreciable effort. I am also facing same problem. Can you tell me the name and cost of your power source/ supply used for 12 units....

May I ask what printer you used to make that color print above? I've been considering affordable options for full color 3d printers and I was wondering what you used to make that model.

Hi Richard, this is a great project, appreciate if you could give me the Python scripts, my email address is chwlvideo@gmail.com. thank you!

Hi Richard, I also have two kids. That's a great project that I started thanks to you. In terms of power requirements, that's about 100 amps, right? How do you manage that? I was hoping to make a portable kit, but here in canada we're running at 120v/15a so powering a rig like that couldn't be done in a normal room.

I, too, would love to learn from your scripts. Could you post them somewhere?

getting closer. Substituted

<print 'ID: ' + ip4>

for < print "ID" ip[caret underneath]4 "-">

now I get:

<print "optons: "optio[caret underneath]n

SyntaxError: invalid syntax.

sorry to be so clueless. Noticed that maybe optons should be spelled options, however this is obviously not the syntax error. Tried single quotes same report.

The instructables page does not allow me to post the code correctly i noticed. Python needs idents for certain segments in the code. Send me a mail with your email and I will email you the code.

Richard,

I pm you with my email addressing regarding emailing the properly formated python scripts.

Thanks

Hallo Richard,

großartiges Projekt - klasse ;-)
Würde mich sehr freuen, wenn Du mir auch die Python-Scripte per Email zusendest. Meine Emailadresse lautet: jshandy@t-online.de Vielen Dank Richard. Gruß Jürgen

I try to do anything similar but have many dudes , perhaps could talk about.

thanks a lot and best regards

Hi Richard. Thx for this great tuto! Would you be so kind to provide me with your python scripts, or are the ones in the downloadable file the right ones?

clifford@clifford.be

And a second question. To manage all your Rasp/cams, I suppose you need a central computer, your Mac I guess. So you've installed Python on your mac and launch your program with it, right? Thx in advance.

This is a cool project. Have you tried to run the image processing software on the server and automate everything?
the_anykey (author)  rocketman2211 year ago
I currently have automated that the images are automatically uploaded to dropbox so they can easily be shared. I am in contact with autodesk about recap. They promised me that soon they will have an API to do this kind of automation. So the entire process can be set in motion by just a single click and (after a wait) get a full 3d model :-)

Hi anykey...fantastic project!!!

I want to do anything similar but have many problems....

im really stupid with programing.....

i have not much money for this project so im thinking forst at 2 pole with 6 pi each and a rotary platform... can do many shoots, 15 or 20 grade ...

Would like if you could help me to control the ip cameras...dont have the code and really dont know how need do...

I would like recibe any more info about your project, think that now you will have at leat 80 or 100 ip cameras working!!!!

Best regards

Awesome contribution. Is the code on github at all? Would love to take a peak!

Really excellent quality of the 3d model. Could you also share one set of pictures from one session. Would be interesting to see the single photos and i would like to test them with my SW Agisoft Photscan. I am doing something similar with small objects. For this i have made a turntable which is triggering my Canon DSLR. With just 15-20 pictures i get pretty good results. Would be great if you could share some pictures to see how it works with Agisoft and how much effort i need to spend to get good results. Thanks for sharing !!!

I am trying to create a rig like this for creating game characters, I would also like to get a hold of some of these images to test in Agisoft Photoscan as well. We are currently working with one camera and a turntable but the movement makes its almost impossible to get a good looking mesh.
