DESCRIPTION
Use UptoPlay to play online the game 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
