# AVDepthData.Quality.low

The depth map is a poor candidate for rendering high-quality depth effects or reconstructing a 3D scene.

```
case low
```

## Discussion

Low quality occurs when the process generating the depth map (such as inference of depth from disparity on a device with dual cameras) cannot find enough distinct key points in the input images, resulting in a large number of invalid depth values in the (pre-filtered) map.
