A method (900) of monitoring utilities (182) by an unmanned aerial vehicle (110) is presented. A rechargeable battery (114) of the unmanned aerial vehicle (110) is charged using an electromagnetic field (152) of a high voltage power line (146). The unmanned aerial vehicle (110) is flown a specified distance (158) from the high voltage power line (146) during the charging (902). Utilities (182) are inspected (906) using a sensor (138) of the unmanned aerial vehicle (110) while flying the unmanned aerial vehicle (110) the specified distance (158) from the high voltage power line (146).

The method comprises : - flying at least a probe carrier flying vehicle (32) above a dropping area on the ground, the probe carrier flying vehicle (32) carrying probes (12) and a launching unit (34), able to separate each probe (12) from the probe carrier flying vehicle (32) ; - activating the launching unit (34) to separate at least one of the probes (12) from the probe carrier flying vehicle (32) above the dropping area; - falling of the probe (12) from the flying vehicle in the ground of the dropping area; - at least partial insertion of the probe (12) in the ground of the dropping area. When the probe carrier flying vehicle (32) is located above a target dropping area, before activating the launching unit (34), the method comprises determining a vegetation information at the target dropping area using a flying vegetation detector (110).
Abstract:
The present application relates to the technical field of unmanned aerial vehicles, and in particular, to an unmanned aerial vehicle. The unmanned aerial vehicle includes at least a first dual-polarized antenna and a second dual-polarized antenna, wherein the first dual-polarized antenna is provided in a horizontal direction of the unmanned aerial vehicle, and the second dual-polarized antenna is provided in a vertical direction of the unmanned aerial vehicle. As the antenna designed in this structure is applied to the unmanned aerial vehicle of the present application, a weak signal in a vertical polarization direction is compensated by a strong electromagnetic signal in a horizontal polarization direction, and therefore an image transmission height of the unmanned aerial vehicle is increased in the vertical direction.
Abstract:
A method and apparatus for controlling a set of sensor platforms (308). The apparatus comprises a map manager (310) and a controller (312). The map manager (310) creates a visibility map (322) for an area of interest (302) for a set of sensor platforms (308). The map manager (310) further updates the visibility map (322) over time while the set of sensor platforms (308) monitors the area of interest (302). The controller (312) controls a route (342) of each of the set of sensor platforms (308) using the visibility map (322).

The invention relates to a method for the layer thickness measurement of soil coverings, in particular in the case of gas and oil pipelines laid underground, wherein the device to be covered is measured and the coordinates thereof in relation to a specified coordinate system are recorded, wherein, after the soil covering has been applied, the course of the terrain over the device is measured and a terrain model (3) is determined therefrom and recorded in the specified coordinate system, and wherein the layer thickness of the soil covering (4) is determined from the coordinates of the device and from the terrain model (3).
Abstract:
A method comprising receiving aerial images captured by one or more unmanned aerial vehicle; receiving metadata associated with the aerial images captured by the one or more unmanned aerial vehicle; geo-referencing the aerial images based on a geographic location of a surface to determine geographic coordinates of pixels of the aerial images; receiving a geographic location from a user; retrieving one or more of the aerial images associated with the geographic location based on the determined geographic coordinates; and displaying to the user one or more overview image depicting the geographic location and overlaid with one or more icons indicative of and associated with the retrieved aerial images associated with the geographic location.
Abstract:
Flight based infrared imaging systems and related techniques, and in particular UAS based thermal imaging systems, are provided to improve the monitoring capabilities of such systems over conventional infrared monitoring systems. An infrared imaging system is configured to compensate for various environmental effects (e.g., position and/or strength of the sun, atmospheric effects) to provide high resolution and accuracy radiometric measurements of targets imaged by the infrared imaging system. An infrared imaging system is alternatively configured to monitor and determine environmental conditions, modify data received from infrared imaging systems and other systems, modify flight paths and other commands, and/or create a representation of the environment.
Abstract:
An unmanned aerial vehicle includes: a vehicle body, where the vehicle body includes a first positioning device; and a landing gear, where the landing gear can be detached from the vehicle body, and when the landing gear is detached from the vehicle body, the vehicle body determines a position of the landing gear by using the first positioning device. Because the landing gear can be detached from the vehicle body and the vehicle body can determine the position of the landing gear by using the first positioning device, the unmanned aerial vehicle, when performing a flight mission, is not affected by the weight of the landing gear, avoiding that the landing gear blocks an image capture device and implementing convenient takeoff and landing.
