Thanks for the quick replies, I will check out both those options. <br><br>-Jeff<br><br><div class="gmail_quote">On Thu, Oct 7, 2010 at 9:38 AM, Ugo Cupcic <span dir="ltr"><<a href="mailto:ugo@shadowrobot.com">ugo@shadowrobot.com</a>></span> wrote:<br>

Hi,<br>
<br>
We coded something doing that. <br>
<br>
You can find it here:<br>
<a href="https://code.launchpad.net/%7Eugocupcic/sr-ros-interface/opticaldataglove" target="_blank">https://code.launchpad.net/~ugocupcic/sr-ros-interface/opticaldataglove</a><br>
<br>
I used usb_cam to publish images from the webcam. Then, the
synchroniser node is in optical_synchronizer.<br>
<br>
It's still really experimental so you may have to modify things a
bit for it to work. If you need more info don't hesitate to contact
me.<br>
<br>
Cheers,<br>
<br>

two cheap usb cameras. I understand the basics of using the
stereo_proc and calibration packages, but what I want to know is
what is the best way to go about creating the actual stereo node
that publishes the images. Is it possible to use two gscam or
usb_cam(or something similar) and remap the topics to look like a
stereo camera? I am not really sure how the calibration data
would get stored used if I did this.<br>
<br>
Or would it make more sense to write an intermediate node that
grabs images from two running usb_cam nodes and publishes them as
left/right stereo image topics (and receives/processes/publishes
the calibration data correctly)? Is there already a package to do
this somewhere?<br>
<br>
At this point, my test will be static, so I am not concerned about
syncing images or timestamps being absolutely correct.<br>
<br>
Thanks,<br>
