 ## Frequently asked questions
 1) *How come some objects visible in the camera images are not annotated?* In the [annotator instructions](https://github.com/nutonomy/nuscenes-devkit/blob/master/instructions.md) we specify that an object should only be annotated if it is covered by at least one LIDAR point. This is done to have precise location annotations, speedup the annotation process and remove faraway objects.
