# smoothedSceneDepth

An average of distance measurements between a device’s rear camera and real-world objects that creates smoother visuals in an AR experience.

```
var smoothedSceneDepth: ARDepthData? { get }
```

## Discussion

This property describes the distance between a device’s camera and objects or areas in the real world, including ARKit’s confidence in the estimated distance. This is similar to [`sceneDepth`](/documentation/ARKit/ARFrame/sceneDepth) except that the framework smoothes the depth data over time to lessen its frame-to-frame delta.

This property is `nil` by default. Add the [`smoothedSceneDepth`](/documentation/ARKit/ARConfiguration/FrameSemantics-swift.struct/smoothedSceneDepth) frame semantic to your configuration’s [`frameSemantics`](/documentation/ARKit/ARConfiguration/frameSemantics-swift.property) to instruct the framework to populate this value with [`ARDepthData`](/documentation/ARKit/ARDepthData) captured by the LiDAR scanner.

Call [`supportsFrameSemantics(_:)`](/documentation/ARKit/ARConfiguration/supportsFrameSemantics(_:)) on your app’s configuration to support smoothed scene depth on select devices and configurations.
