I compiled pdp_openCV not that long ago on ubuntu 10.4. I don't remember how I did it but I think that's because it was pretty straightforward and went without hitch. It all worked pretty well as I recall. No big surprises. The help patches got me started.<br>
<br>But do you need that for a laser tracker? Seems like pix_subtract and pix_blob would do the job... Max Neupert has some nice patches using this technique IIRC:<br><a href="http://web.uni-weimar.de/medien/wiki/Bewegungsmelder">http://web.uni-weimar.de/medien/wiki/Bewegungsmelder</a><br>
<br>You could also use pix_blob's color weight inlet effectively since you know you are looking for red.<br><br>-John<br><br><div class="gmail_quote">On Thu, Oct 28, 2010 at 2:22 PM, Pagano, Patrick <span dir="ltr"><<a href="mailto:pat@digitalworlds.ufl.edu">pat@digitalworlds.ufl.edu</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">I would like to make a laser tracker that tracks the points from a red laser beam.<br>
I would like to see if I can use pdp_ openCV to track the laser and when I hover the laser over some video long enough it acts as a click, is this possible?<br>

Thanks for the cool link!<br>
