# CalibrationMetrics

The CalibrationMetrics message is part of the [Dynamic
Calibration](https://docs.luxonis.com/software-v3/depthai/depthai-components/host_nodes/dynamic_calibration.md) system. It
provides compact numeric scores used to evaluate calibration readiness and confidence.

It is intended for runtime monitoring and automation logic (for example, deciding when to recalibrate or when to trust the current
calibration state).

## Key fields

 * dataConfidence: Score between 0 and 1, describing how good the currently collected calibration data is (usefulness of
   observations).
 * calibrationConfidence: Score between 0 and 1, describing confidence in the current calibration estimate.

Use these metrics together (and compare them against your own baselines/thresholds) when building recalibration policies.

## Examples of functionality

CalibrationMetrics is received on metricsOutput when calibration metrics are computed by the Dynamic Calibration node.

 * [Calibration integration
   example](https://github.com/luxonis/depthai-core/blob/main/examples/python/DynamicCalibration/calibration_integration.py)

## Reference
