About AprilTag Detector

This app provides core apriltag detection functionality directly from APRIL Robotics Lab alumni. Supports all apriltag2 tag families. Tunable settings for decimation, hamming error, etc available. Detected valid tags will be outlined in the preview window.

Supported tag families include:
- 36h11 (recommended)
- 36h10
- 25h9
- 25h7
- 16h5 (used by FIRST Robotics Competition in 2023)

Performance is based on user settings and devices, if you're running into slow detections, consider increasing the decimation factor or number of threads used.

The app is open source and available here: https://github.com/johnjwang/apriltag-android

The core tag detection is from University of Michigan's APRIL Robotics Lab, which is distributed with the BSD 2-Clause License and is available here: https://github.com/AprilRobotics/apriltag
