Re: Multiple Light Tracking with Distinct Light Boxes

Is that first@slashdot? Or is it correct as is?

Re: Multiple Light Tracking with Distinct Light Boxes

It is correct as it is, I'm not cool enough to have an email address at Slashdot :P

Re: Multiple Light Tracking with Distinct Light Boxes

In case you missed my post on your team's blog, Team 1648 would love to be able to have a copy of this code!

Thanks in advance,

Re: Multiple Light Tracking with Distinct Light Boxes

I would very much like to see this code -- the demo looked amazing!

Re: Multiple Light Tracking with Distinct Light Boxes

It seems you had talked about setting up a CVS respitory somewhere, but i cannot find it and wasn't able to get the copy of the code.

If you can, can you please provide me a copy of that code, thanks

Re: Multiple Light Tracking with Distinct Light Boxes

I already have this code and I have played with it a lot. Now I am interested in using it practically. How do you actually "choose a light" to go to, and ignore the other. Also, when the camera sees 2 lights, it twitches back and forth between the two. Is there a fix for that? Also, if I want to go "in between" the 2 lights, how would I do that? With the twitching, it doesn't seem possible. Thank you in advance for your help.

Re: Multiple Light Tracking with Distinct Light Boxes

hey cool - and cool to you for sharing. we lost our programming mentor to a heavy work load, so we are trying to do autonomous in Easy C, but having trouble with the camera. Might you help us a bit? thnks team 1696 in the stix (Montana - not exactly the hotbed of C ) chuckm@3rivers.net and rcurtis3.3rivers.net

Re: Multiple Light Tracking with Distinct Light Boxes

Heh has anyone actally figured out how to pick the blob, either left or right?

other than that i wanted to ask one more quesion, i am not sure but anyone knows how to calculate the width of each blob?

please help if anyone knows

Regards

The blob with the lower y coordinates will be closer (or the other way around if your camera is upside down). But you might consider going to the one that is more infront of your robot.

width = T_Packet_Data.x2 - T_Packet_Data.x1;

Good Luck,

Re: Multiple Light Tracking with Distinct Light Boxes

I sent this e-mail out tonight to everyone that was on my mailing list.

As a result of snow delays and other complications, our team has changed directions and will no longer be pursuing the camera. As a result we can no longer continue developing the dual light code. If any of you are interested in still obtaining the beta code, I will be placing a link on the original Chief Delphi post shortly. It is stickied in the CMUcam sub-section of the Programming forum. Best of luck in their upcoming competitions, and we hope to see you at Nationals.

Thanks again, and good luck!

(For example, pwm outputs are configured as in Mr. Watson's streamlined code, so there definitely is some (potential) non-neutral activity on every pwm. Please see user_routines.c if you need to comment this out.)

2. I should clarify that this code does not yet move the pan/tilt servos. We have started working on that but it's not yet debugged completely. Instead of waiting, I wanted to at least get this base code out.

3. If your camera is mounted upside down (see Kevin's post in the sticky on chiefdelphi) then the GUI representations will be upside down. I think everything else should work (I'm not totally sure of this).

I have attached a zip file with the uncompiled python scripts and the camera code for the robot. The executable python scripts were too large to attach. If you have any further questions I will try to get back to you.

Re: Multiple Light Tracking with Distinct Light Boxes

Let us know if we can help with the situation, and thanks for posting it for all to enjoy.

Good luck,

Re: Multiple Light Tracking with Distinct Light Boxes

Hello!
I am new to chiefdelphi and, well, new to FRC. Our team has been having trouble with the Virtual_Window command. Whenever we send the command, our camera seems to initialize. This makes the camera physically move back to it's starting position... We must be doing something wrong, we just don't know what. We came up with an alternate method of tracking the rack without using virtual window (only using a corner of the "blob" we see.) This solution is messy at best, so if anybody could help, please either reply or email me at neutrino15[at]gmail[dot]c0m. (the 0 is a o in com)..

Thank You!

We use this, it works quite well. Just aim to either corner (x1 or x2) instead of the center (mx).
