摘要： The present disclosure relates to a location measurement method using a processor. The location measurement method includes: acquiring a surrounding image photographed by an electronic device; acquiring first location information of the electronic device using a global navigation satellite system; and acquiring second location information obtained by correcting the first location information using the surrounding image photographed by the electronic device, in which a correction value for correction from the first location information to the second location information is calculated by detection of an image including a static object included in the photographed surrounding image from a pre-stored real-world image map.

摘要： Error and integrity evaluation during a position determination, includes: recording position values (P−N, P−2, P−1) and calculating clock errors of a receiver via time-discrete runtime measurements by a satellite navigation system; recording a first pseudo-distance at a later time via time-discrete runtime measurement by the satellite navigation system; extrapolating a position value (P′0) of the receiver at the later time and extrapolating a clock error of the receiver at the later time; establishing a distance (r′0) between the extrapolated position value (P′0) of the receiver and the position of a satellite (S0) of the satellite navigation system at the later time, wherein a quality measure for the usability of the position determination with the satellite is obtained by forming a second pseudo-distance based on the sum of the established distance (r′0) and the extrapolated clock error at the later time and comparing the second pseudo-distance with the first pseudo-distance.

摘要： In various embodiments, crowd sourcing techniques are provided to determine beacon altitudes that may then be used in 3D positioning of UE. Some techniques may crowd source beacon altitudes based on global navigation satellite system (GNSS) position fixes obtained by UE. Other techniques may crowd source beacon altitudes based on uncalibrated pressure measurements obtained by UE. Still other techniques may combine beacon altitude crowd-sourcing and pressure sensor calibration on UE. Such techniques may make inferences based on line of sight (LOS) between UE and beacons, determined using signal strength, connection status, and/or timing measurement. The techniques may be implemented separately, or as part of a combined system that determines beacon altitudes in diverse manners. Once beacon altitudes are known, that may be used to determine 3D positions of the UE (e.g., by trilateration, multilateration or other positioning techniques).

摘要： Methods and systems for providing mechanisms for automated inventory control are provided. In embodiments, an operational workflow for providing automated inventory control includes automated data collection and automated image data analysis. The automated data collection includes capturing image data for a storage facility by a capturing device (e.g., an unmanned aerial system (UAS)). The automated image data analysis includes functionality to detect objects (e.g., containers, trailers, empty slots, and/or other objects) appearing in the image data (e.g., using a machine learning (ML) model), to identify the objects in the image data (e.g., using the ML model), to inspect the objects (e.g., including determining a condition and/or location of the objects) based on the collected image data and metadata associated with the image capturing device and correlated to the image data (e.g., using an advance mathematical rule-based analysis), and/or to generate results that may be used by an inventory management system.

摘要： System and method of wireless communication in UAV systems that uses geolocation-based beamforming. The antenna array on the transmit device is first calibrated to compensate the random phase errors of the antenna. During operation, the geolocations of the UAV and its remote control and the rotational position of the transmit device are used to determine a beamforming direction. A beamforming vector is selected based on the beamforming direction. The beamformer on the transmit device then beam forms the antenna array such that data or other information can be transmitted to the receive device in the beamforming direction.

摘要： Systems and methods are provided for deterministically estimating whether the location of a computing device that is fixed or mobile is inside a building or not using location data. Particularly, the system may compare 3D geoposition uncertainty region of a location to a 3D volumetric structure shape of the location, and determining a confidence value based on the comparison associated with a likelihood that the location associated with the computing device is indoors or outdoors. Various states of the computing device are supported by the substance of the disclosure, including indoor and outdoor states.

摘要： A method for determining the position of a vehicle involves determining a plurality of position hypotheses by comparing landmark objects detected by a sensor system of the vehicle with landmark objects stored in a map, in particular in a map section. By analyzing all position hypotheses and filtering out all false information using probabilistic analysis, a position hypothesis with an integrity value is determined. A position hypothesis with a position accuracy sufficient in a predetermined way for determining the position of the vehicle is determined by filtering according to predetermined limit values.
