Unmanned aerial vehicles (UAVs) are used nowadays in a wide range of applications, including monitoring, mapping, or surveying tasks, involving magnetic field mainly for geological and geophysical purposes. However, thanks to the integration ultrasound-aided navigation indoor UAV flight planning development sensorics, acquired images can be further used, example, enhance based on physical quantities image identification risk areas manufacturing industrial halls, where workers exposed high values electromagnetic fields. The knowledge spatial distribution fields also provide valuable information from perspective technical cleanliness. This paper presents results achieved with original fluxgate magnetometer developed specially modified UAV. Since had wider frequency measurement, up 250 Hz, DC (Direct Current) low components could evaluated. From obtained data, 3D using spline interpolation algorithms written Python programming language were created. visualization measured plots offer an innovative view area interest.
