Camera Framerate Problems

Our camera can display images through the computer, and track colors as they move. But we only get about 10 fps, and I believe the camera is supposed to display 30 fps.

Does anybody have any ideas on how to increase the frame rate?

Re: Camera Framerate Problems

Decrease the resolution. You might find you get useful images at 160x100.

Re: Camera Framerate Problems

You might even find you get good images at 160x100 decimated 2 by 2.

Re: Camera Framerate Problems

Apparently turning off the camera at the dashboard increases the framerate substantially. Other than that, size seems to be the most important factor.

Re: Camera Framerate Problems

In general, when you are looking for bottlenecks in code, the tool you want to use is called a "profiler". it tells you which parts of your code are using the most memory and cpu. in labview it's under block diagram->tools->profile->performance and memory. once you've identified which parts are causing the slowdown, then you may be able to think of clever ways to re-code that part to be faster.

Re: Camera Framerate Problems

Turn off the dashboard, and reduce the image resolution.
