Re: pic: Three colors???
 

Now for the easy part... getting the camera to track these colors!! :ahh: By the way... does any one who has done this already feel like giving me some color values for red or blue to put in camera.h? ;)

it looks like :D :D :D :D four light

Re: pic: Three colors???
 

Question: could you replicate the same multi-color light idea by using multi-colored glow sticks? You would have white, blue, red, green, and orange as possible colors. Plus, glow sticks would be cheaper. (I would test this idea on our own robot, if only our robot had been programmed to actually track lights :( )

Now what you need to do is add an EDU/Vex controller so you can program it change the way one would if it were part of the field.

Re: pic: Three colors???
 

My guess is yes, since I was told I couldn't wear green glowsticks our team was distributing at AZ if I was driving on the field.

Those colors would only be the start; there'd also be purple, yellow, and probably some shaded colors as well.

Re: pic: Three colors???
 

The problem with all those colors is that the camera has enough trouble tracking a bright green light. How do you think it will do with red, blue, and purple. :ahh:

Re: pic: Three colors???
 

The blue should be no problem.... the red is what has me worried :ahh:

also, changing color configs on the fly should be no problem but searching for all three colors at the same time.... a bit more difficult.

Ours never really had noticeable trouble tracking the green light, but our shooter bounced around alot so maybe we just didn't notice.

Yeah, searching for multiple colors at once is going to be interesting. I don't know how the camera will react if the target is moving either.

Re: pic: Three colors???
 

I don't think that will be the biggest problem. When we test our camera, we pull out the green light and move it around a bit to make sure the camera is properly testing it. I don't see that being much different than a moving target. However, that also depends on the code that you have written for the camera.

It will be interesting to see if the target is both moving AND changing colors at the same time.

Re: pic: Three colors???
 

I'm still kind of skeptical about these. I think these could be configured in different ways. There could be different colored lights, total of 6 on a field. They could be located seperately. They could be located high or low. They could be pulling our leg all together. Just my thoughts.

Re: pic: Three colors???
 

a moving target can be tracked pretty easily.

it would track the target when someone ran back and forth with it when we tested.

There definitely will be a use for the camera this coming season, and I bet more than one color that can be tracked. If you guys think hard enough, we've already had to track 4 different colors.

Re: pic: Three colors???
 

you also have to remember that 2 or more sets of lights could easily make another color such as orange, or purple, or even turquoise!!?!? :D

Re: pic: Three colors???
 

Nice set up. With a total of 12 tubes, you can individually control them to generate 4096 discrete color hues (which will be helped if you put a crystal panel and a diffuser over the light box, but that is a detail). That would be a pretty good mix, and should allow you to test a lot of different possible conditions. Just don't forget to program in the "vibrating paisly" mode....

OMG IS THAT A CLUE!!!!!!! :p
