A package coupling apparatus for securing a package to an unmanned aerial vehicle (UAV) is provided. The package coupling apparatus includes a support plate configured to be secured to an upper surface of the package and a handle extending up from the support plate. The handle includes a handle opening and a bridge that extends over the handle opening, wherein the bridge is configured to be secured by a component of the UAV.

A technique for managing an unplanned contingency landing of a unmanned aerial vehicle (UAV) includes determining by the UAV that the unplanned contingency landing is imminent, capturing aerial images of a ground area below the UAV with an onboard camera system as the UAV descends towards the ground area, semantically analyzing the aerial images to classify objects at the ground area into object classifications, depth analyzing the aerial images to determine above ground level (AGL) heights associated with each of the objects at the ground area, selecting a preferred landing site for the unplanned contingency landing that is coincident with one of the objects at the ground area based upon a contingency landing policy that ranks contingency landing sites based upon a combination of the object classifications and the AGL heights; and nudging the UAV towards the preferred landing site as the UAV descends towards the ground.

A payload coupling apparatus having a housing comprising an outer surface extending around a perimeter of the housing, an upper portion above the outer surface and including a tether attachment point, and a lower portion below the outer surface; a first slot extending into the outer surface of the housing thereby forming a first lower lip on the housing beneath the first slot; wherein the first slot is adapted to receive a handle of a payload; and a second slot extending into the outer surface of the housing thereby forming a second lower lip on the housing beneath the second slot; wherein the second slot is adapted to receive the handle of the payload.

An uncrewed aerial vehicle (UAV) includes a fuselage extending along a first direction from a rear end to a front end. The fuselage has a cross-sectional area at an intermediate position between the front and rear end. An external payload storage area is positioned at the intermediate position and is configured to receive a payload that is secured to the fuselage and that extends laterally outward from the cross-sectional area of the fuselage. A drag reduction device is coupled to the fuselage. The drag reduction device has a length extending from a free end to an attached end that is secured to the fuselage, a width that extends perpendicular to the first direction of the fuselage, and a depth. In an operating position, the drag reduction device is positioned in front of the payload storage area, is spaced from the payload storage area, and extends outward from the fuselage.

In some embodiments, techniques are provided for analyzing time series data to detect anomalies. In some embodiments, the time series data is processed using a machine learning model. In some embodiments, the machine learning model is trained in an unsupervised manner on large amounts of previous time series data, thus allowing highly accurate models to be created from novel data. In some embodiments, training of the machine learning model alternates between a fitting optimization and a trimming optimization to allow large amounts of training data that includes untagged anomalous records to be processed. Because a machine learning model is used, anomalies can be detected within complex systems, including but not limited to autonomous vehicles such as unmanned aerial vehicles. When anomalies are detected, commands can be transmitted to the monitored system (such as an autonomous vehicle) to respond to the anomaly.

In some embodiments, a computer-implemented method for simulating an unmanned aerial vehicle (UAV) to improve control system performance is provided. A computing system obtains ground truth aerial imagery for a region that depicts the region during a first state. The computing system determines a route for a simulated UAV within the region. The computing system generates, based on the ground truth aerial imagery, predicted aerial imagery that depicts portions of the region associated with the route. The computing system generates simulated aerial imagery that depicts portions of the region associated with the route during a second state different from the first state by providing the predicted aerial imagery to a machine learning model. The computing system simulates travel of the simulated UAV along the route during the second state by providing the simulated aerial imagery as simulated input to at least one control system of the simulated UAV.

A method for perception validation of an unmanned aerial vehicle (UAV) includes: acquiring an aerial image of a ground area with an onboard camera system of the UAV, generating a semantic above ground altitude (AGL) estimate with a neural network trained to output the semantic AGL estimate in response to the aerial image fed as an input to the neural network, generating a motion estimate or a position estimate based upon perception sensor data output from a perception sensor disposed onboard the UAV, and cross-validating the motion or position estimate against the semantic AGL estimate.

A computing system in an infrastructure support network for uncrewed aerial vehicles (UAVs) may receive, from a UAV, aerial observation data of a ground-based cluster of charging pads for UAVs, the cluster comprising assets including the charging pads arranged in a layout and fiducial markers distributed across the layout. The aerial observation data may comprise position measurements of the UAV at aerial geolocations above the cluster, and vector positions of one or more assets with respect to the aerial geolocations. The computing system may generate a map graph from the aerial observation data, the map graph comprising (i) nodes corresponding to both the aerial geolocations and vector positions, and (ii) edges between pairs of selected nodes, the edges corresponding to distances between selected nodes and including measurement uncertainties. The computing system may generate a spatial map of cluster assets of the cluster by computationally optimizing the map graph.

A method for unmanned aerial vehicle (UAV) mission planning includes acquiring a target aerial image of a geographic area representative of the geographic area illuminated by one or more artificial light sources, identifying a location of the one or more artificial light sources based on the target aerial image, rendering a simulated aerial image representative of the geographic area illuminated by the one or more artificial light sources at night using a digital surface model of the geographic area, the location of the one or more artificial light sources, and an irradiance parameter for the one or more artificial light sources, identifying one or more regions within the geographic area as having sufficient lighting for UAV operation at night based on the simulated aerial image, and generating a mission plan for the UAV based on the one or more regions within the geographic area.

A technique for localization of an unmanned aerial vehicle (UAV) includes: acquiring aerial images of a terrain below the UAV with an onboard camera system of the UAV while the UAV is flying a mission along a preplanned route over the terrain; generating a current optical flow map based upon image pixel motion between consecutive images in a sequence of the aerial images; comparing the current optical flow map to reference optical flow maps stored onboard the UAV, wherein the reference optical flow maps are precomputed from a model of the terrain along the preplanned route; and determining a position in at least two lateral dimensions based on the comparing.
