What is Drone Inspection?
In its simplest definition, a drone inspection involves an uncrewed aerial vehicle (UAV) equipped with sensors and cameras that scan difficult, unsafe, or costly locations.
Instead of dispatching someone up a cell tower or into a tight area, operators use a drone, which gathers high-resolution data without any danger, flying in the most convenient way possible.
How Drones Work in Inspections
A drone inspection occurs when a UAV flies a pre-planned or controlled flight and uses its onboard payload — such as 4K cameras, thermal sensors, or LiDAR — to capture pictures, videos, and other sensor data.
The data obtained is then processed and analyzed to identify such problems as cracks, corrosion, heat leaks, or structural defects.
Key Components of Inspection Drones
The modern UAV inspection systems usually include:
- The visual inspection equipment has high-resolution cameras.
- Infrared and thermal sensors to identify heat irregularities.
- LiDAR scanners to produce 3D maps.
- GPS and stabilization.
- Software platform for data analytics and reporting software.
History and Evolution
Drones first appeared in military surveillance in the first half of the 20th century. It later became used in civilian applications as a photography device, a surveying tool, and as a commercial and industrial activity.
Drones inspection has become a common practice in all sectors thanks to the fast development of sensors and Artificial Intelligence (AI), as well as automation. In the current day, UAV inspection is more accurate and reliable than the traditional inspection modes.
Types of Drones Used
Various drone platforms are created to meet different inspection needs, which are efficient, safe and accurate in different industries:
