Can you profile more clearly what is eating the compute?  Rectification should just be a lookup so that&#39;s fast ... you don&#39;t say what your image size is.<br><br>Gary<br><br><div class="gmail_quote">On Mon, May 10, 2010 at 9:43 AM, Shadow <span dir="ltr">&lt;<a href="mailto:sacha@shadowrobot.com">sacha@shadowrobot.com</a>&gt;</span> wrote:<br>

<br>
I just made ROS work with my firewire webcam and used opencv to<br>
calibrate it. But even with just using opencv to display my stream, it<br>
uses about 50% of my processor (Intel 4300)<br>
Is there any explanation to this ?<br>
<br>
Thanks.<br>
