The present disclosure relates to a detection method and system for an underground space by joint use of fixed sensors and unmanned aerial vehicle (UAV) movement detection. The detection system includes underground space sensor nodes and an underground space UAV. The underground space sensor nodes are configured to perform fixed monitoring based on an adaptive optimal layout strategy for an underground structural space. The underground space UAV is configured to calculate a first virtual force, and realize movement detection by means of a virtual force-guided path planning algorithm. The underground space UAV is configured to calculate the first virtual force based on the electronic telescopic anti-collision bars, a second virtual force based on a static perception probability and a third virtual force based on structural evolution knowledge, and realize a fixed node-guided UAV flight detection mode by means of the virtual force-guided path planning algorithm.

An aerial vehicle safety apparatus includes a piston member, a cylinder that accommodates the piston member and is provided with a hole through which the piston member protrudes outward at time of operation, a push-up member that is pushed up in one direction by the piston member, an expandable object that is pushed up while being supported by the push-up member, a gas generator as a power source that moves the piston member in the cylinder, and a first member and a second member that serve as a cylindrical container that accommodates the piston member, the cylinder, the push-up member, the expandable object, and the gas generator. The expandable object is stored in the container so as to form a plurality of layers in a radial direction.

There are provided a safety apparatus and an aerial vehicle including the safety apparatus, in which a lid and an opening end of a container are fixed before operation more firmly than a conventional art to be less susceptible to an external environment. A safety apparatus includes a piston member 10, a cylinder 14 that accommodates the piston member 10 and is provided with a bore 13 through which the piston member 10 protrudes to the outside during operation, a push-up member 15 that is pushed up in one direction by the piston member 10, an ejected object 16 that is pushed up while being supported by the push-up member 15, and a gas generator 17 that moves the piston member 10 in the cylinder 14. A bottomed cylindrical portion 19 of the push-up member 15 has a hole 53, the hole 53 has a substantially identical shape to a shape of one end of a rod 12, and the one end of the rod 12 is fitted to the hole 53. The bottomed cylindrical portion 19 and the rod 12 are fastened and fixed by a bolt member 15.

A shield system for an unmanned arial vehicle (AUV) is provided. The shield system includes inner shield members rigidly mounted to at least the rotor arms of the AUV and outer shield members shock mounted to the inner shield members. The shield system defines opening for sensors, payload or mechanical portions of the UAV.

A remotely controlled unmanned aerial device for use in proximity or in contact with high voltage powerlines, includes an unmanned aerial vehicle and an electrically conductive shield forming part of or operatively coupled to so as to encapsulate the unmanned aerial vehicle. When in the presence of a high voltage powerline, the unmanned aerial vehicle either when bonded-on or within the corresponding magnetic fields of the powerline, so as to transfer the powerline potential in whole or in part to the unmanned aerial vehicle, electrically energizes the conductive shield around the unmanned aerial vehicle while leaving components of the unmanned aerial vehicle within the shield substantially electrically unaffected by the voltage potential.

An introduced autonomous aerial vehicle can include multiple cameras for capturing images of a surrounding physical environment that are utilized for motion planning by an autonomous navigation system. In some embodiments, the cameras can be integrated into one or more rotor assemblies that house powered rotors to free up space within the body of the aerial vehicle. In an example embodiment, an aerial vehicle includes multiple upward-facing cameras and multiple downward-facing cameras with overlapping fields of view to enable stereoscopic computer vision in a plurality of directions around the aerial vehicle. Similar camera arrangements can also be implemented in fixed-wing aerial vehicles.

This disclosure describes systems, methods, and apparatus for automating the verification of aerial vehicle sensors as part of a pre-flight, flight departure, in-transit flight, and/or delivery destination calibration verification process. At different stages, aerial vehicle sensors may obtain sensor measurements about objects within an environment, the obtained measurements may be processed to determine information about the object, as presented in the measurements, and the processed information may be compared with the actual information about the object to determine a variation or difference between the information. If the variation is within a tolerance range, the sensor may be auto adjusted and operation of the aerial vehicle may continue. If the variation exceeds a correction range, flight of the aerial vehicle may be aborted and the aerial vehicle routed for a full sensor calibration.
