Embodiments according to a first and second aspect of the present invention are based on the core idea of flying along the object for detecting a feature of an object and detecting at least a part of the object with a capturing unit with a first resolution and providing, for those areas of the object that comprise the feature, images with the second resolution that is higher than the first resolution.

The present invention relates to a method for inspecting a facility (1), wherein the method comprises at least the automatically executed steps of: capturing (100a) optical data from at least one facility part (12, 13) of the facility (19), capturing (100b) acoustic data from at least the same facility part (12, 13) of the facility (19), and jointly evaluating (200) the captured optical data and the captured acoustic data.

The present invention relates to a method, a system and a computer program product for detecting and/or predicting need for elevator maintenance. A first digital twin of the elevator is generated using data collected by one or more sensors of an unmanned aerial vehicle (UAV) operating within the elevator shaft. One or more threshold values are defined for parameters associated with one or more components of the elevator appearing in the first digital twin. At least one second digital twin of the elevator is generated using data collected by one of more sensors of an unmanned aerial vehicle (UAV) within the elevator shaft. Each parameter of the elevator in the at least one second digital twin is compared to the respective one or more first threshold values. A request for maintenance of the one or more components of the elevator is automatically triggered if any one of the compared parameters meets or goes beyond the respective first threshold value.

The present specification discloses a mobile scanning device (30) for scanning wear conditions of treatment panel modules (13) of a treatment deck (14) in vibratory treatment apparatus (10), the mobile scanning device (30) including a support structure (11), steerable transport means (12) carrying the support structure (11) along a predefined course or a selectable steered course on or over the treatment deck (14), the support structure (11) carrying power means (16), drive means (17) powered by the power means (16) to drive the steerable transport means (12) scanning means (18) to scan a lower zone (42) below the support structure (11) to establish scanned information, the scanned information being reflective of at least wear levels occurring on the upper surfaces (31) of the treatment panel modules (13), and transmission means (23) arranged to transmit the scanned information to remote control means (20, 21) external of the treatment deck (14).

A method of inspecting a curved surface using an unmanned aerial vehicle (UAV) by activating a plurality of sensors having at least respective portions disposed on the curved surface, the method including flying the UAV to a proximity of a first of the plurality of sensors; activating the first sensor by an activation device coupled to the UAV; attaching at least one magnetic leg of the UAV to a ferromagnetic surface proximate the first sensor, the at least one magnetic leg having a magnet, moving the activation device coupled to the UAV towards the first sensor while the at least one magnetic leg is attached to the ferromagnetic surface; and, when the activation device is positioned in proximity of the first sensor, receiving first sensor data from the activated first sensor via the activation device.

A method includes obtaining, at an unmanned aerial vehicle, a flight plan for the unmanned aerial vehicle. The flight plan is based on an aircraft type of an aircraft to be inspected. The method also includes coordinating, with a lighting control device onboard the aircraft, activation of a particular exterior light of the aircraft based on the flight plan such that the particular exterior light activates or deactivates when a particular sensor of the one or more sensors is located (i.e., positioned and oriented) to perform a sensing operation on the particular exterior light. The method further includes performing the sensing operation on the particular exterior light using the particular sensor. The method also includes determining a functionality metric associated with the particular exterior light based on the sensing operation.

A propeller guard 2 includes: a propeller guard body 10 configured to surround a propeller 30 of a flight vehicle 20; and a repulsive member 40 provided to protrude on the propeller guard body 10 and including a first end and a second end to exert repulsive force outward from the propeller guard body 10, in which the first end 41 of the repulsive member is located outside an outer edge of the propeller guard body 10 as viewed from vertically above.

A pothole monitoring and repair system for a road surface includes at least one UAV which includes a video camera, a video processor, a computing unit and a global positioning receiver. The UAV generates video streams of road surfaces using the video camera which are processed by the video processor to extract road frames. The computing unit generates a geo-fenced area of the road surface, and determines whether there is at least one pothole in each of the road frames within the geo-fenced area. The cloud server generates a map of the geo-fenced area, labels location coordinates of each pothole on the map, identifies and labels geographical features in the road frames within the geo-fenced area, extracts pothole features in the road frames, and uses a classifier to predict repair actions based on pothole features and geographical features, which are presented on a front end interface.

An apparatus, system, or method for performing work on electrical power lines and/or splices on electrical power lines that may include an unmanned aerial vehicle (UAV), a power line measurement device, a support frame selectively releasably attached to the UAV, and a plurality of flexible dielectric attachment lines attaching the power line device to the support frame. The power line measurement device configured to determine measurement data by measuring a width of a live electrical power line and/or a splice on the electrical power line. Each of the attachment lines may be attached to a corresponding attachment point on the support frame and a corresponding attachment point on the power line measurement device.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for ground control point assignment and determination. One of the methods includes receiving information describing a flight plan for the UAV to implement, the flight plan identifying one or more waypoints associated with geographic locations assigned as ground control points. A first waypoint identified in the flight plan is traveled to, and an action to designate a surface at the associated geographic location is designated as a ground control point. Location information associated with the designated surface is stored. The stored location information is provided to an outside system for storage.
