# Drone inspector for civil infrastructure

## TL;DR

Researchers used drones with cameras to detect tiny movements in bridges, helping assess structural health.

## Contribution

The novel use of hovering drones with cameras to detect submillimetre displacements in civil infrastructure.

## Key findings

- Cameras on drones can detect submillimetre displacements in bridge spans.
- This method provides a new way to assess structural integrity of civil infrastructure.

## Abstract

A recent publication in Nature Communications describes the use of cameras on hovering drones to detect submillimetre displacements of bridge spans.
