Hey all! For any #frc folks, are there any good resources for vision? I'd like to use the apriltags to align and score, but I don't know much and was hoping to learn more.
To anyone, if you know of resources, papers, or anything else relating to vision, and how that ends up making stuff happen in the code, I'd appreciate anything you could share.

@aberrant68 I wrote a blog post on the AprilTags a little while ago (https://blog.fixermark.com/posts/2022/april-tags-python-recognizer/).
For recognizing them in competition, the team I’m working with is using Raspberry Pis with PhotonVision (https://photonvision.org/). This solution is pretty plug-and-play (modulo the challenge of getting a Raspberry Pi and networking switch mounted and powered on the robot chassis)—once you get it working, it’ll auto-recognize the tags and dump all the relevant data (either via NetworkTables or directly via a library for the robot code).
An announcement by FIRST Robotics earlier this year revealed an interesting bit of news: next year’s kit would include AprilTags as vision targets. I’m completely unfamiliar with these, so I figured it’d be fun to dive in and see what they’re all about. Generating some tags AprilTags are a so-called “fiducial” system that identifies not only a position and orientation, but an identifier code as well via a block encoding scheme, conceptually similar to a barcode but with some design features useful to making them easy to comprehend from multiple angles.
