Using Canon EOS as webcam

Hello, there :D

Are there anyone who have tried Canon EOS with DAVID3.2? I've been waiting for DSLR to work with DAVID.

After long waiting, DAVID Team did it again. So I bought Canon 600D immediately.
Since there is no guide about 3.2 to lead me I tried with my shallow knowledge that I inquired in this Forum
But it doesn’t work as I expected. It seems DAVID recognizes CANON but I couldn’t see Live View through DAVID.

I set camera live-mode and connect via USB that comes with 600D product package.

Am I wrong? Should I do something to see live view in DAVID? What about cable, is it right to use USB not HDMI?

Any opinion would be appreciated.
Thank a lot in advance

Hi Byung,
i bought my eos 550d just yesterday for the same reason.
To work with David i do as follow.
1. Install eos drivers (before connct the camera).
2. Set camera mode to manual (M in the selection ring)
3. Switch off all automatic functions (auto iso, lighting etc..).
4. connect to pc and start David.

For sure someone can explain this proceure better than me; i'm still learning.

Yes, 550d is older than 600d (some months i think). I bought 550d 'cause i found a good offer.
I think there is some little differences between this two models and if i can use it with David you can do the same.
Currently i use it directly with David (without any external software) and it works like a normal webcam.
I made only some test but i achieved some good result (great result if compared with my previous scans).
First thing i notice is the great improvement of projector's calibration procedure; with the pro 9000 is hard to obtain a perfect sine waves and a good/flat line without noise in phase error.
I don't know if, for SL scan, is better an SLR or an industrial camera but, for sure, an SLR is more versatile.
In conclusion i think that an EOS SLR is a good buy.

It's strange. when you use eos utility, live view function works properly?
This evening i would try to use extrawebcam; it allow to change some eos settings. It should be more comfortable.

Hi,
EOS 550d and 600D are similar excepted the orientable screen on 600d.
So, if it works with 550D, it could works with 600D.
Normaly you just have to plug usb connector on your lap top.
David recognizes eos automaticaly.
Set your camera on "M".
May be you will have to play with the live view button of your camera until you can ear the mirror motion sound.

Best regards.

Thierry

Sorry, forgot to mention: that test version requires the .NET Framework 4.0.

So what happens when you connect to the 600D?

hi Byung-gyu,

Thanks for the report.

Please start the DAVID3.exe from a CMD Shell on your 64-bit system. Do you get any helpful error messages?

Please try this version 2675: does it run on Win7-64?
http://www.david-laserscanner.com/freew ... 0.2675.zip

@all:
Has anyone else tried EOS cameras? Do you have the same problems?
We only have a 500D at hand, no problems here... :?
