Finger Lakes Regional and natural light

Hello all, I'm looking for information about the venue at RIT this weekend. Specifically if there are windows that allow natural light onto the field?? Our vision camera was thrown off because we were using the same spectrum to sight in the high goal. The large windows at RPI would cause the vision to think the robot was on the correct target but the tolerance we set would not allow the shooter to fire (which was good because we would have had many boulders enter the stands).

Anyway, pics of past field setups, pics of windows or alternate ways your team may filter out for your vision capabilities will be great.

Thanks in advance,

Re: Finger Lakes Regional and natural light

For those people working on this issue, the color temperature of sunlight and tungsten light will affect your tracking. Sunlight is generally in the 5600-5900K range while uncorrected tungsten could be much cooler around 3200K. If you are simply looking for green, then you may not have as significant trouble. Forcing white balance may help if your camera is capable of that.

Re: Finger Lakes Regional and natural light

The short version is: yes there are large windows and you should really find a time on thursday before practice matches to go on the field and calibrate it to be safe. But, they are much farther away and typically cause far less ambient light and issues than the venue at tech valley.

Here's the best picture I could find (quickly) kind of showing that dynamic.

I haven't heard of many teams having issues with this at Finger Lakes since the change to reflective tape.

Thanks Al for your input. That information helped out last night while we were fine tuning our vision.
