# PhotonVision — FRC Computer Vision
|
|
|
|
**Website:** https://photonvision.org/
|
|
**Purpose:** Free, fast, easy computer vision for FRC
|
|
|
|
## What It Is
|
|
|
|
PhotonVision is the largest FOSS FRC vision project. It runs on a coprocessor (Raspberry Pi 3/4, OrangePi 3, etc.) and handles:
|
|
- AprilTag detection and pose estimation
|
|
- Object detection (ML-based)
|
|
- Multi-camera support
|
|
- Driver mode integration
|
|
|
|
## Why We Use It
|
|
|
|
Team 2890 runs PhotonVision on **Mothman** for AprilTag detection. It's our primary vision system.
|
|
|
|
## Key Capabilities
|
|
|
|
| Feature | Description |
|
|
|---------|-------------|
|
|
| AprilTag Tracking | Out of the box FRC target support |
|
|
| Multi-Tag Pose | Fuse all available data for peak accuracy |
|
|
| Camera Calibration | Per-camera intrinsics maximize homography accuracy |
|
|
| ML Object Detection | Hardware-accelerated inferencing for gamepieces |
|
|
| Driver Mode | Same camera for driving and vision |
|
|
| Multi-Camera | Run as many cameras as hardware supports |
|
|
|
|
## Getting Started
|
|
|
|
1. Download PhotonVision image for your coprocessor
|
|
2. Flash to SD card
|
|
3. Connect to network — start tracking in minutes
|
|
4. Configure via web dashboard
|
|
|
|
## Connection to YAGSL
|
|
|
|
PhotonVision works alongside YAGSL (swerve). YAGSL handles drive control, PhotonVision handles vision targets.
|
|
