+1. Initial Setup
+    1. For each camera
+        * For each resolution
+            * [Calibrate](https://docs.photonvision.org/en/latest/docs/calibration/calibration.html) FOV
+        * Relative to the center of the robot (See Transform3D [VisionCamera.VisionCamera](./VisionCamera.java))
+            * Measure translation (x,y,z)
+            * Measure rotation (roll, pitch, yaw)
+    1. For each field
+        * Load the AprilTag map layout into PhotonVision (See AprilTagFields.class)
+2. Periodically at runtime
+    1. For each camera
+        * If estimated robot pose is available (i.e. AprilTag is visible)
+            * addVisionMeasurement to drivetrain odometry (See [Drive.addVisionMeasurement()](../drive/Drive.java))
