# Camera calibration

##### Calibration status

Example overview you can wire to real telemetry:

- Cameras in good state: 94%.
- Needs re-calibration (pose/face off-center): 7 vehicles.
- Frequent low PoseNet confidence (< 0.5): 2 vehicles.

##### Sample calibration checklist

1. Center the driver’s face and upper torso in the frame.
2. Ensure daytime and nighttime lighting are both tested.
3. Verify PoseNet keypoints align with eyes, nose, and shoulders.
4. Check OpenCV face/eye detection success rate over 1–2 minutes.
5. Save calibration profile, then re-run a short validation trip.

##### Vehicles needing calibration

Vehicle | Driver | Issue | Last check | Action
--- | --- | --- | --- | ---
Truck 05 | Samir Patel | Low PoseNet confidence, driver often at frame edge | Today · 07:12 |
Truck 18 | Alex Chen | Night-time glare reduces OpenCV eye detection | Yesterday · 23:04 |

##### Camera calibration workflow (example)

Use this as a reference when you wire the real calibration flow:

1. Ask the driver to sit in their normal driving position and look forward.
2. Adjust camera so that the driver’s head and shoulders stay within the guide box.
3. Capture a short calibration clip (daytime and nighttime, if possible).
4. Verify PoseNet and OpenCV success rate in a quick test run.
5. Save the calibration profile for this vehicle.
