Hi! I Installed Linux 10.10 (network version in a SD Card 2GB) on my Beagle
Board and I'd like know how is it possible use OpenCV on it.
sudo apt-get install libcv-dev
should get you what you want, more here:
http://packages.ubuntu.com/source/maverick/opencv
1) Is there a simple tutorial online?
2) I saw that it's possible use the Beagle Board's DSP for the OpenCV, how
can I do it?
At this time not really, but that would be a good summer project, are
you interested?
Regards,
I have another problem 
After I install the OpenCV I connected my USB WebCam to the
BeagleBoard and the BeagleBoard recognize it with this message:
[13751.735961] usb 1-2.4: new full speed USB device using ehci-omap
and address 15
[13751.857849] gspca: probing 0c45:613c

[13751.860900] gspca: found int in endpoint: 0x83, buffer_len=1,
interval=100
unfortunately when I open Cheese, the immage that show the video is
completly black.
I had think that the problem was the alimentation but changing it, the
result is the same.
At this time not really, but that would be a good summer project, are
you interested?
Yes, I'm interested. Can you give me more information about it?
Thanks a lot,
Diana

I haven't actually seen Cheese work. 
You should have a /dev/video0 mplayer does a good job of using it..

There was a project last year that has since kind of stalled, that had
some success but could use new help..

I installed mplayer, but the error is the same.
This is the error that shows when I write "dmesg" on term:

Have you an idea what this is?

Yeap.. "bandwidth not wide enough - trying again" , sounds like you
have too many devices on the usb bus..
Make sure your connected to the ehci hub and you don't have a lot of
high bandwidth devices on it..
Regards,
I have a BeagleBoard xM which has four usb ports and I'm using
external power supply.
I have try to invert the usb port betweent the other dispositives
(mouse and keyboard) but nothing.
And I have try to use only one usb port with the web cam and take away
the other dispositives, but nothing.
What is the problem?
Regards,
Diana
It might just be futile with the gpsca driver then, specially with
only 2 true usb ports on the beagle....
If your running out of bandwidth on the ehci, can you move the camera
to the otg port?
omap_ehci -> smsc95xx -> network
-> hub port 0 -> keyboard
-> hub port 1 -> mouse
-> hub port 2 -> camera
-> hub port 3 -> empty
omap_musb -> otg port -> empty?
I'd try a different camera, non gpsca..
Regards,
I tried with the otg port and
I tried to change four different camera...
Nothing 
Hey Artemide,
I'm interested in the OpenCV project after reading about it a lil from
the given website and reading these posts. Are you considering
helping out? Have you contacted the project leader at all?
Thanks.

Hi Naveen,
I'm a university researcher and in this moment we are studing the
Beagle Board for facedetection, facerecognition and other application.
We have some problem about the using of the webcam and about the using
of the DSP.
Are you considering helping out?
Why no?
Regards,
Diana
You might try Angstrom with gnome gui. It likes gspca and UVC
webcams.
