# cameraCalibrationData

The imaging parameters with which this depth data was captured.

## Declaration

```swift
var cameraCalibrationData: AVCameraCalibrationData? { get }
```

## Discussion

Discussion Using depth or disparity map data to render effects into a corresponding image or to perform computer vision tasks requires knowledge of the camera parameters that generated the depth data. Depth data captured by an AVCaptureDevice object contains camera calibration data that includes such information. note: Depth data read from a file (see the init(fromDictionaryRepresentation:) initializer) or transformed through arbitrary editing of its data map might not contain calibration data.
