Although aerial thermography is several years old, it was inaccessible for most applications due to high price of the flight hours. Aerial thermography recently meant the usual application of helicopters and expensive thermal cameras. The acquisition and operating costs were high; the application use was very limited.At present, as a result of the highly intensive development of UAV (drones), there have been principal changes in this field. The aim is to use UAV with small and light thermal cameras with incomparable smaller acquisition and operating costs.

As this concerns a very modern field, which is in its infancy, then before the commissioning of the Workswell WIRIS system there were restricted commercial applications that meant excessive compromises for a practical application. What has been available up to now could rather simply be called a “sensor” rather than a measuring system or measuring device.
