Conflicting Vision Target Lasers

[arithehun]

So we are planning on targeting the vision target by searching for an RGB color that we shine using a laser. Pretty typical. Let's just say we use a blue laser. What if another team uses a green laser and points it at the same target? How would our program work then? It seems that I must be missing something because this would be a very big problem.

FYI, lasers in this context probably would not be allowed. Some other form of light source, ie, LED ring, would work perfectly fine and is legal.

As to your question, it's a tradeoff between tolerance and specificity. Making your accepted color range narrower would clean up your signal but make it more prone to failure due to lighting conditions, and vice-versa.

If you're using an LED ring, keep in mind that the retro-reflective tape, by nature of its design, has a very narrow angle of reflection. I can be standing next to my team's robot, and not even see a hint of green reflecting off the targets from our LEDs. To see it at all I have to put my head quite close to the camera.

Oh, it does? Thanks! And I think our particular laser is legal, but I'll double-check.

where did you learn how to process? from a website or a mentor? and if from a website what website

Hint: Most lasers cannot change their color.

unless you use a filter, possible made a glass.
