  • Patent number: 12612776
    Abstract: The present disclosure relates to a device configuration, and a method for performing an imaging survey within a survey space using an unmanned aerial vehicle. An unmanned aerial vehicle with at least four rotating blades, and a control unit which controls the rotation of the at least four rotating blades. The unmanned aerial vehicle includes a survey camera in a position on a chassis of the unmanned aerial vehicle, between at least one rotating blade positioned on the side in the direction of travel, from among the at least four rotating blades, and at least one rotating blade positioned on the opposite side to the direction of travel, and wherein, when flying above a surface in which a liquid is at least partially present, the unmanned aerial vehicle flies while at least partially preventing scattered liquid from reaching above the chassis.
