KINECT Turntable and Mount for 3D Scanning : First Ever TinkerCAD Design ! by Welle417 Mar 18, 2013

Description

March 21th, 2013 UPDATE

I have had a couple days to experiment with the Kinect "Reconstruct Me" software, testing scannable area, optimal distance, etc.

As I suspected, a distance range from 2-5 feet is the only real "scannable" area. This sort of 3d modeling would be ideal for larger objects for the purpose of miniaturization. Kids toys shrunk down, etc. It does not pick up finer detail on smaller objects however. I had already been searching for an alternative to this with a regular webcam/camera. The one that seems most promising at present is the vi3Dim Reconstruction program. What's unfortunate about it is that it is all built from open-source software and should be offered to non-commericial license for free... It sells for $350!? No thanks... I will continue to look for ways around this obscene cost to a very BASIC program. (It is initialized and run through command prompt-lol).

I will eventually seperate my files on here when I find a suitable program and system for using the turntable, with a different camera. The kinect base is still handy and when I get it completely measured I will be able to utilize that as a base and scanning handle as well.

That's all I have at the moment - keep checking back for more updates about my search for the best FREE or Economy-priced 3D Scanning/Modeling software.

Until next time. Live Long and The Force be with You,

I have simplified and smoothed the design quite a bit today... I also started almost from scratch in order to correct some mis-alignment issues... Everything on the table and arm should be a somewhat even number in my file. I changed my idea for the time being about the adjustable lift, instead thought a "sweet spot" should be found initially for MOST objects that fit in the table - seeing how much the KINECT can capture with its wide viewing angle. The table can be printed in just 3 pieces now and the ability to customize the type of stand you may like is now possible. The "base plate" that i eyeballed to fit the KINECT, is able to clip on to the tower i made and the tower has the slot to allow it to do this. The spot for the tower to fix to the base can be used for any number of things. After I fine tune this entire thing more, i may mock up a "light fixture" to be attached to another leg in case of the need for less shadows. Ideas for this keep springing up all over - even the thought of a USB-controlled motor for the turntable... Could be fun.

Until tomorrow - Live Long and The Force be with You,

March 18th, 2013: Greetings Thingiverse!

I had my first hand at 3D designing some random things today on TinkerCAD - testing its limitations and seeing if i could make anything useful. I remembered seeing http://reconstructme.net/ with the free to use Kinect Scanning software, so i decided to use a planetary gear i found on here to make a "lazy susan/turntable" and adjustable mount for my kinect whenever my printrbot gets here.

I understand all my alignments and tolerances are probably questionable, but I just wanted to hack out a rough idea of where i am going to take this. As i said this is my FIRST EVER from-scratch design in any CAD program so, please let me know some suggestions, or please tweak it and iron out the problems and if anyone is perhaps feeling ambitious... print it! I have all the pieces in a single file right now, as i haven't taken the time to see how i should break them apart... Any help would be appreciated. Thanks!

Some Notes The main table has tabs to slide into the cutouts in on the planetary gear. The Gear center has a large cutout for it to fit on the secondary base (brown) The primary base is for the kinect "adjustable lift" and is somewhat optional This has a cutout for the secondary base to settle into for more stability. But the side tower for the kinect slots into the primary base with the hex slot(s).

Have you tried "David Laserscanner" (http://www.david-3d.com/?section=Downloads) the software is free. I have not tried it yet since I only have a Kinect, but do plan on purchasing a webcam soon. I also don't have my 3D printer yet, I backed Boots Industries B.I. v2.0 Delta printer and waiting for it to come. Anyway, I found about "David Laserscanner" through "Life Hacker" (http://lifehacker.com/5822730/make-a-3d-scanner-out-of-a-webcam-laser-pointer-and-some-software). Thank you for your project, I plan on makin it.
I have tested scanning with skanect and I can verify that it is A) not too close when scanning small items B) Since it is a pieced kit from the get go you can move it to proper position from the center of the table. A couple pointers thought would be to mark the table as it helps the kinect with depth perception. I use post it notes tabs from dollar tree.
sounds good! :)

nice :D I've been working on something similar. Almost have it done. Its much more industrial though. Once I finish it physically this weekend I'll post it to ya.
sounds good! :)
Very cool. But i think Schorhr was probably right about the distance. I find that you need to be at least a foot away when scanning small objects. Please let me know how this works out when you test it. I have not been very successful in getting good quality scans of small objects with my kinect.
Neat! But isn't this too close to scan objects?
I cannot be sure yet as I didn't get a chance to mess with the software and test the scan able area of the Kinect. I know that I'm 6ft 3 and from 6 ft away it can capture my whole body. So roughly 6-7 in away would capture a 6 in cubed area ideally. I am going to change the main base to an X shape and put the tower back further. I am also toying with the idea of cutting out a gear track under the table for a turntable motor as well as a screw-gear driven lift and lower mechanism for the Kinect platform. I don't know enough about motor control and programming unfortunately but I'd like to figure away to get push-button motion for a completely autonomous scan. Even better would be a plugin for the capture program.
