Thanks, I set both exposure and white balance to "Hold Current" In the begin.vi. I'll have to wait till friday to actually change camera settings on the camera itself.

Sorry my explanation wasn't more detailed. The camera has flash storage. If you don't want the program to control something in Begin, just delete it and the camera settings will be used. You can use the browser or vision assistant to view and change settings.

I believe we opened the camera settings in a browser window and did it there.

There is a Camera Performance Example that can be used to set and hold the white balance.
Just add a "Set WB" .vi after the while loop and before the CLOSE.vi, and configure it to "Hold current". Make sure you hold a plain white object (piece of paper works well) in front of the camera for ~15 seconds while running the vi. Make sure the object fills the video frame and reflects the light from the environment into the camera. Then make sure you exit by pressing the "Stop" button on the front panel. This will "Hold" the current white balance in the Flash Ram in the camera.
Then just set the White Balance in the Begin.vi to "Hold current". This will cause the camera to use the calibrated white balance value from then on, or until you change it at the next competition you attend.

I'm curious what people's images look like with the very bright LEDs and messing with exposure times.

We used 6 blue LEDs, and did not change any camera settings, and got good results.

We actually held a white piece of paper about 4 inches away from the camera to blind itself, then set it to auto.

Using purple LEDs with good results. We just thought that would be the most uncommon color in the enviroment and picked that.

Re: Ring light not bright enough in camera feed
 

Interesting... Are they from Superbrightleds.com, because we couldn't get a good image at any real distance with the purple ring lights from there.

4 green LED rings work perfectly for us.

Re: Ring light not bright enough in camera feed
 

Out of curiosity, how many of the teams who commented on this post are using the Axis 206 vs. the Axis M1011. We tried both and noticed that it is much easier to change the settings on the M1011 (but unfortunately our 1011 won't connect to the Driver Station wirelessly).

We noticed that the M1011 had a direct control over exposure via a sliding bar going from 0-100 (doesn't require the light fiddling) and it also had a contrast setting. Both of these were absent from the earlier 206 model.

Which DB? The SmartDB requires that you enable anonymous access.

If you were asking me, both dashboards did not work, and we had enabled anonymous access.

Re: Ring light not bright enough in camera feed
 

Can you describe the setup, and did the camera work at any other point in the season? Can you ping the camera from the DS laptop?

No, they are strips from pepboys! They are so bright, they are difficult to look at and easily saturate the targets if the camera is not set correctly

We play tomarrow at Lenape in New Jersey. Look up what matches 2607 is in any you might see us use them. Woo! 6th place so far!
