Vision calibration during a competition

Hello, I was wondering when I could calibrate my vision code during a regional. Is it during the practice matches?

The reason I say is this is because it would be easier to get on the robot over usb directly on the field and download an image immediately.

If I can’t do that I guess I could capture an image using a joystick button and save it.

Any help would be appreciated, thanks.

We spent about an hour on the actual field right before practice matches so say 10 ish they open on practice day with games at 12 about six bots were calibrating…we never did get out auto aim to work due to camera being obstructed by parts of our bot…we’ll see if we can get it going this week…fingers-crossed

Thanks!

But just to clarify:
As in the robot on the field connected over usb?

We were on the field and wired to the bot not sure if it was USB

Thanks!

There is usually a field access period. Thursday morning before practice rounds start. Check the calendar for your regional.

I would caution you strongly to not assume that you will have access to the fields. Create a system that will take pictures during practice matches and comptetion matches. Access to the field can be severely limited at times.

I agree that this is a good idea, but the manual guarantees 30 minutes available for measurement and calibration per section 5.5.8. It should take a very extreme circumstance to be ignoring this guarantee.

In the five years I’ve been coaching, we’ve had that garunteeed time actually given to us about 6 times. That’s out of 13 competitions, so less than 50% of the time, you get it everytime.

The default dashboard saves one image per second to the Documents/LabVIEW Data. If you make a custom DB, you can extend that. You can also hit the red circle on the DB to record the match video to an AVI. You can then extract images from the AVI.
