Aerial digital images of the inside of historic and sensitive buildings can now be obtained quickly and safely, courtesy of a new miniature airship from aerial imaging specialist Skycell.
Skycell claims its airship can provide high-resolution still or video images of inaccessible or poorly lit areas of a building without causing disruption or the need for intrusive scaffolding. A live video link to the ground allows the inspection team to make on the spot assessments and direct the airship accordingly.
The soft hull of the 2.2m diameter, 1kg airship means it cannot cause damage. It is virtually silent and can remain airborne for several hours.
The technology was trialled in York Minster in August last year, investigating a suspected crack in the stonework 30m above the choir.
It is now available commercially, with a more powerful outdoor version due in March.
