ReconstructMe Public Beta

ReconstructMe Public Beta

Postby MagWeb » Mon Feb 27, 2012 3:31 pm

Hello,

ReconstructMe Beta was just released.
http://reconstructme.net/

ReconstructMe is a software to capture 3D data (a 360°scene) using a single MS Kinect or the Asus Xtion within a 1x1x1m volume in realtime and free ( for non commercial usage). It exports meshed surfaces to STL, OBJ ...
Do not expect laserscan or SL quality, but the results maybe enough for a lot of things

Thanks for the advice!

From your point of view how is the best hardware for this cool software? the Microsoft Kinect or the Asus Xtion?
Thanks in advance,
Mattia

Hi, I'm one of the developers of ReconstructMe. Both Kinect and Asus Xtion are basically the same, they use the same sensor. So the results will have the same quality.
If you want high resolution and realtime, you need a fast graphics card.

The precision is worse than a laser scan, but it has some other advantages: e.g. shiny black surfaces seem to work much better than laser scanner

Hi

if use faster video card and shiny black surface . better then laser scanner ? .

any result out there how detail looks like ?

thanks

Hello martinus,

thanks for the public beta, your software seems cool.
I'm testing it on 3 notebooks, and I have the OpenCL problem with a nVidia Quadro 3500FX, the powerfull card of mine (mobile version for a M90 DELL workstation).

I know that the M90 computer have an old hardware that don't support (also if latest driver installed) the OpenCL, but, because Quadro are maybe the more professional and powerfull (and maybe moddable) videocards from the nVidia family... I ask if there is a way to "force" the OpenCL on these videocards?

With my less performign GeFroce (other notebook) OpenCL works and also your software, but so slowly (cheap videocard).

Or there is an other way, instead OpenCL, to make ReconstructMe working? I ask this because this sounds like a "restriction" for all the "not-so-young" hardware.

Thanks in advace for any kindly answer,
Mattia

Right now ReconstructMe makes heavy use of parallelization on the graphics card, there I think OpenCL is the best way to go right now. It is also possible to run OpenCL on the CPU, you can install Intel's OpenCL SDK (see http://reconstructme.net/usage) but this will most likely be even slower.

Another option is to use the offline mode: First you can record a data stream, which does not need too much horsepower. Afterwards you can replay this stream and generate a CAD model from that. See http://reconstructme.net/usage/#offline

If you have any specific OpenCL errors, please post them to the reconstructme mailing list, that's where we more frequently look

Thank you very much.

I'm going to test your suggestions.
See you soon on the ReconstructMe site.

Many thanks,

ReconstructMe - Firsts tests

Postby hal » Thu Mar 01, 2012 9:39 pm

Hello,

Here a test os scanning and aligning and one dedicated to the joshualee post about black surfaces.
I've used the software on a laptop with nVidia GeForce G102M, Work slow but work.

I had some issue with alignment: martin, the deformation of the scans are related to my poor GPU or to my bad movements of the sensor?
I've tried to move the sensor very smoothly and slow...

MatM_RecoMe_First test_1.jpg

The software reconstruct a limited portion of the environment space, 1x1x1m, so we must to save every "completed cube" each time, and start again.

MatM_RecoMe_First test_2.jpg

As you can see, some big deformations are there: how to solve? Comments and suggestions are welcome.
Please not in the left side the small portion of the lamp, on the table. As the computers' monitor, the lamp was turned on (out was night, in the room that lamp was the only one turned on). Because the Kinect technology, this 3D scanner can catch surfaces that are in prohibitive conditions for 3D scanner based on the visible light.

MatM_RecoMe_Blacks.jpg

A dark lather jacket on a grey and black metal-lather chair. Kinect don't have problems with dark surfaces (only transparent surfaces are, obviously, not seen).
Sometimes shiny surfaces reflect badly the IR dots and appear some artifacts (as on the white-shiny plane of the table). Not big problems with semi-trasparent objects and hair/fur.

Hope that the ReconstructMe software can grow up soon. Seems promising.

More tests

Postby hal » Fri Mar 02, 2012 4:32 pm

Hello, here som more tests with the lates ReconstructMe beta.

MatM_RecoMe_Darks1.jpg

Here above an other "black" scene: the bag is black, the door-frame is black and little shiny. The door have glass, so Kinect see throw it.

MatM_RecoMe_Etleva.jpg

... and some other test with living objects: collegues.

Hope that the "stitching volumes" feature came soon.

Hardware tested

Postby hal » Fri Mar 02, 2012 5:19 pm

My first attempts were done on 4 different video cards, with the Microsoft XBOX360 Kinect.
These the results:

- ATI Radeon HD 4570 M 512Mb = don't work
- nVidia Quadro FX 3500 M 512Mb = don't work
- nVidia GeForce G 102 M 512Mb = work slowly
- nVidia GeFroce GTX 280 1024Mb = work perfectly

Hope this helps,
Mattia

Mattia you are very good !

if i try with more faster then GTX 280 . more detail result?
what about scan for small things like 500mmx500mm ?
may be i have to put some lens on the Kinect?
i am crazy about this way to scan .
i will buy fastest video card today , and i will try

thanks

hi,

i am also trying reconstructme at the moment. especially scanning persons i do not manage to get as good results as you get (f.e. the girl sitting on the chair). i am missing some details (mouth,...).
i do reconstructme.exe --realtime --highres. can you give some information about the setup, lighting,...?

have a nice day!

mmm but I use the Kinect as you, no special settings (becose no way to have customized settings).
I just move the Kinect in front of the subject. But please note that also me don't catch details in --highres mode. The result si like a melt wax statue (and ok, this is enough for me!).

So, we must to wait some news from the team, but I don't think that the details can be increased. The best update will be to scan more than the limited 1x1x1 m volume at time. Adn seem this feature cames (I hope soon).
Please, try to consider this software as a friend, not a brother, of David: differnte technology behind, different purposes and results... but they can be compenetrated as well.

thanx fou your reply, mattia.

i also see david somewhere else. lets see how reconstructme turns out after some time. i found out that they want to release some free and some not free versions in march. there is also a google discussion on using some kind of addonlense to the kinect for scanning smaller items.
