For the surveying of facades of high buildings (e.g. church towers) or roofs that are not load-bearing can be problematic for stationary 3D-Laserscanners such as Leica Total Stations or FARO Focus Premium. So, in these cases, aerial drones are used for surveying. Digital video or photo cameras are installed on the drones, which are operated remotely. Large areas can be surveyed over and data-captured in a relatively short time. The results of this data capture process can be 3D point clouds or 3D mesh models, which can complete the building survey in conjunction with the data capture by tachymeter and 3D laser scanner.
The reference of the measurement series of the different measurement systems to each other is established via control point measurements.
In addition to the technical drone flying and surveying, the service also includes the necessary approval procedures for obtaining the flight permit. Depending on the location of the object, this can be an additional effort not to be underestimated, which we will gladly take over for your project.
