    摘要: Examples are disclosed that relate an approach for automatically annotating a LiDAR point cloud of an airport with classification labels. In one example, a computing device comprises one or more processors configured to execute instructions stored in memory to receive LiDAR data for an airport environment, wherein the LiDAR data includes a LiDAR point cloud including a plurality of points in the airport environment, segment the LiDAR point cloud into a ground region and a non-ground region, automatically cluster, via a trained machine learning model, different points in the non-ground region into a plurality of non-ground segments, automatically annotate, via the trained machine learning model, the plurality of non-ground segments with classification labels selected from an airport domain, and output a panoptic labeled LiDAR point cloud including the plurality of non-ground segments labeled with respective classification labels and the points in the ground region.

    摘要: A method, apparatus, system, and computer program product for detecting an object relative to a vehicle. A projected component of a laser radiation is emitted as a set of laser beams into an atmosphere from a vehicle. A backscatter light generated in response to said emitting the laser beam into the atmosphere is received to form a received backscatter light. The received backscatter light is filtered using a tunable optical filter system to form a filtered backscatter light. A control component derived from the laser radiation is filtered using the tunable optical filter system to form a filtered reference light. A set of parameters relating a presence of the object relative to the vehicle is determined using the filtered backscatter light and the filtered reference light.

    摘要: A surveying system includes a surveying device, a UAV, and a processor. The surveying device includes a first camera and a combination of a laser scanner and a total station. The UAV is mounted with a second camera. The processor includes an image data receiving unit, a laser scanning data receiving unit, a specified part receiving unit, a flight plan setting unit, and a camera direction setting unit. The specified part receiving unit receives a desired part specified in a photographic image taken by the first camera. The flight plan setting unit sets a flight route of the UAV that contains a position of a viewpoint for viewing the desired part, on the basis of laser scanning data. The camera direction setting unit sets directions of the second camera during flight of the UAV along the flight route, on the basis of the laser scanning data.

    摘要: A VTOL UAV (1) comprising a chassis (3), a propulsion system (5) mounted on the chassis (3), electronics (12) including a flight control system, and a 3D LIDAR sensor (10) mounted on the chassis. The 3D LIDAR sensor has a laser beam 360° rotation axis ( R ) and an azimuthal scanning angle ( α ) in a range of 70° to 110°. The propulsion system comprises a plurality of propellers (6) with motors (7) configured for flight without wings, including static hovering flight, the VTOL UAV comprising a yaw axis ( Z ) about which it can rotate upon itself. The 3D LIDAR sensor is statically mounted on the chassis such that the LIDAR laser beam 360° rotation axis ( R ) is inclined at a LIDAR inclination angle ( β ) with respect to the yaw axis (Z) in a range of 35° to 50°.

    摘要: A multi-fiber optical sensor system (401, 402, 403, 404) includes a light source (675) configured to generate light energy, a transmitter fiber (130; 230; 330; 622) configured to receive the light energy from the light source and to project light energy out of a projecting end of the transmitter fiber over a transmitter fiber field of view (232; 432), and a plurality of receiver fibers (120, 121, 122, 123; 220, 221). Each of the plurality of receiver fibers has a receiving end aligned proximate and substantially parallel to the projecting end of the transmitter fiber and is configured to receive a received portion of the projected light energy reflected from a target within a receiver field of view (240, 241; 422, 424). The multi-fiber optical sensor system also includes a lenslet array (180; 280; 380) configured to shape the transmitter fiber field of view and give the transmitter field of view a finite cross-sectional area. The lenslet array has a plurality of lens (188, 190, 191, 192, 193) corresponding to the transmitter fiber and each of the plurality of receiver fibers and is further configured to shape the receiver fiber field of view, tilt the center of the field of view with respect to the axis of the projected light energy for each of the plurality of receiver fibers and give the receiver fiber field of view for each of the plurality of receiver fibers a finite cross-sectional area. The multi-fiber optical sensor system also includes a detector configured to detect the portion of the projected light energy received by each of the plurality of receiver fibers. The receiver fiber field of view for each of the plurality of receiver fibers crosses the transmitter fiber field of view between a first crossing point at a distance R min from a lens axis and a last crossing point at a distance R max from the lens axis. There is a center crossing point R mid at a point where a centerline of the receiver fiber field of view for each of the plurality of receiver fibers crosses a centerline of the transmitter fiber field of view. The range between R min and R max for each of the plurality of receiver fibers defines a detection zone (290, 291, 292, 293, 294, 295) such that each of the plurality of receiver fibers has a unique detection zone. Targets include a hard target and/or constituents of a cloud atmosphere.
