Drones have been around for a while now. They are no longer an emerging technology. Also, we have been using them for inspection. But how far has that gone?
The obstacles that were rife in the early days of drone inspection have been dealt with. High-quality sensors with resolutions of up to 100MP are now in use. Legislation around the use of drones, even near restricted areas, is now more straightforward. Drones themselves are more advanced, with technology like collision avoidance.
The use of drones in inspection has become convenient, leading to the widespread adoption of the practice across industries. This article will analyze the state of the art of drone inspection, touching on multiple aspects.

The State of Drone Inspection Technology
Major breakthroughs have been made in all areas of drone inspection technology, making the practice a lot more convenient.
To start with, drones have a higher range and can carry heavier payloads. Heavier payloads allow for higher-quality sensors. Additionally, innovative drone technology like collision avoidance is at advanced stages.
Major strides have also been made in the sensors used.
High resolution is a must-have for successful inspection, especially when looking out for millimeter-sized damage. In this regard, modern drone cameras have done exceptionally well and are capable of up to 100MP images.
Lenses have grown more versatile. The most advanced aerial camera lens comes with multiple field-replaceable options. Such versatility, coupled with the high resolution that drone cameras are now capable of, has proved indispensable in applications like drone wind turbine inspection.
In addition to improvements in the sensor, such as in the versatility of the aerial camera lens, the variety of sensors available for use has grown.
Drone cameras are no longer limited to RGB photography. They can capture four-band imagery, making it possible to acquire more insights from inspection. Drones can also be equipped with payloads that enable the capture of thermal and ultraviolet radiation for use in inspection.
The Type of Drones In Use
Currently, most inspection use cases rely on multirotor drones. The next most popular type is the fixed wing drone and the least popular is the hybrid drone.
Research shows that over the next decade, this order will persist.
Multirotor drones are preferred because they are easy to maneuver. You can easily navigate into and out of tight spots. Also, they have vertical take off and landing capabilities.
The most notable advantage of the fixed wing drone is range and speed. If your inspection use case requires you to capture images over a long distance, such as in drone powerline inspection, this might be the best option.
Still, the multirotor drone is suitable for most use cases and continues to be a favorite.
Industries Using Drone Inspection
Some of the industries that heavily rely on drone inspection include:
Agriculture.
Utilities.
Construction.
Oil and gas.
Mining.
Over the next decade, the use of drone inspection in the agriculture and construction industries is expected to rise significantly.
In agriculture, the use of drones to inspect crop health is on the rise. So is the use of drones to collect data to promote precision agriculture. This has been made possible by cutting edge technology such as the ability of drone cameras to capture color infrared imagery.
In construction, drones are used to inspect the progress of construction and measure it against projections. But even after construction, the use of drones to inspect the state of buildings for maintenance purposes is rising. Drones are a cheap, fast, and inexpensive alternative to inspection techniques like scaffolding.
In the energy industry, drone powerline inspection, drone wind turbine inspection, and drone oil rig inspection have been some of the most popular use cases.
Conclusion
Drone technology has evolved a great deal since drones were first used for inspection. Drone inspection has become more affordable, convenient, and effective.
Thanks to the wide adoption of the practice in a variety of industries, it is easier than ever to start drone inspection. There are companies dedicated to offering such services. You can outsource your inspection needs to them.
Alternatively, you can do it in-house—it has never been easier. The cost of drones has dropped to the point where it is sustainable for small companies to launch their own drone inspection programmes.
The future of drone inspection promises to be even more exciting. This is undoubtedly a space to watch.
