I think my title says it all…
Basically I’m curious to see as to how far a limelight may be able to read the vision targets on the Outer Goal, and if it would be any sort of accurate. Unfortunately right now we don’t have the shop space/distance to get a good test on this. However, I’m most curious if you could vision track the Outer goal from behind the Control Panel, I realize this is unrealistic but its peeked my attention.
Here’s a little drawing I made to clear things up.
I’m pretty sure limelight could do a full court shot if it were legal. The LEDs have to be able to reflect the tape, and those things are bright.
Is that shot unrealistic?
Obviously I didn’t test it out, but from that distance you’ll need to shoot in a quite shallow arc, so you’ll need a very high velocity which might be hard to reach.
Even if the LEDs reflect, I’m not sure you’ll be able to effectively differentiate the target from the rest of the image from that distance.
You can tune the vision pipeline to only see that hue of green. It sticks out like a light.
Everything else is black
Yeah I know, I’m just not sure that from great distances you’ll see a hexagon as you’ll see in shorter distances.
Yeah it might just look like a blob. But it’s a pretty big hexagon.
we were pleasantly surprised with how far we got ours to detect, I don’t know how far out we got, but the vision target is much larger than last years.
Keep in mind the stadium lighting in differing arenas.
Not sure you need vision tracking if you build a hardstop into your frame…
I’m trying to avoid this so driving under the trench is an option
No. It’s possible. But it’s against the game rules.
Show me that rule.
If you’re having trouble finding it it’s because it doesn’t exist.
The size of the target doesn’t matter if the limelight isn’t able to resolve the width of the tape. You can use the FOV of the camera, the resolution, the distance from the target, and the width of the tape to determine how many pixels wide the tape will show up on the limelight. It would probably need to be several pixels wide for the vision algorithms to work reliabily on it, although dilation may help.
It is legal. Check G9. Full court shots are defined by the entirety of your bumpers being within your sector zone. You can take the shot as soon as a piece of your bumper is past the opponents initiation line.
I would love to see some screenshots of the filtered camera feed from nearly full court and from the trench if there’s a team with access to a full field.
Rule G.9 says that full court shots are not allowed.
Your can shoot from anywhere on the field, except for your sector (the one closest to your driver station and opposite the one you shoot in). Shooting from your trench run (or the opponents if you’re risky) is allowed.
