Abstract: A control method for controlling a yaw angle ?z and a roll angle ?x of a vertical take-off aircraft comprising at least two drive groups arranged in opposite side regions of the aircraft so as to be spaced apart from a fuselage of the aircraft is presented. Each drive group comprises at least one first drive unit. The first drive unit is arranged so as to be spaced apart from the fuselage to pivot about a pivot angle ? into a horizontal flight position and a vertical flight position.

Abstract: The invention relates to an observation device having a location determination functionality for the high-accuracy determination of the spatial location and thus the position and orientation (for example, Euler angles: azimuth, elevation angle, and roll angle) of the observation device by analysis of a recorded camera image of the terrain surrounding the camera by means of the three-dimensional map information of a digital terrain model (DTM). For this purpose, the observation device comprises a camera having an objective lens and a camera sensor, a data memory, a sensor system, an analysis unit, and a display screen.

Abstract: In some implementations, a method performed by data processing apparatuses includes receiving stored map data corresponding to a digital map, identifying a discrepancy between the digital map and a physical space which the digital map represents, updating the digital map to correct the identified discrepancy, storing the updated digital map, and optionally providing the updated digital may for presentation on a device display.

Abstract: In a marker detection method in which a sensor unit (11) that includes a plurality of magnetic sensors arranged in a vehicle width direction is used to detect magnetic markers (10) laid in a road, a feature value that represent symmetry of magnetic distribution, which is the distribution of magnetic measurement values obtained by each magnetic sensor included in the sensor unit (11) is generated, and threshold process regarding the feature value is executed to determine the possibility of the presence of magnetic generation source other than magnetic marker (10), that causes disturbance, and hence to suppress erroneous detection.

Abstract: A positioning method includes determining a positioning coordinate (x101,y101,z101) of a positioning device in a scene coordinate system o-xyz based on one or a combination of (1) an estimated coordinate (x1,y1,z1) of the positioning device in the scene coordinate system o-xyz; and (2) positions of image objects of one or more reference illumination sources of a plurality of illumination sources in a scene image, fixed coordinate positions (x0, y0, z0) of the one or more reference illumination sources of the plurality of illumination sources in the scene coordinate system o-xyz, and an included angle ? between an x-axis of the scene coordinate system o-xyz and an x?-axis of a positioning device coordinate system o?-x?y?z?.

Abstract: An autonomous mobile robot includes a drive system to maneuver the autonomous mobile robot about an environment, a first magnetic field antenna system responsive to a magnetic field pulse to generate a first signal, and a second magnetic field antenna system responsive to the magnetic field pulse to generate a second signal. The magnetic field pulse is emitted by a magnetic field emitter system in the environment. The autonomous mobile robot further includes a controller to execute instructions to perform operations including reorienting the autonomous mobile robot based on the first signal and the second signal.

Abstract: A marker detection method in which a magnetic detection unit (11) of a vehicle side that includes a plurality of magnetic sensors arranged in a vehicle width direction is used to detect magnetic markers (10) that are laid in a road, the method executes detection of a center position in the vehicle width direction of a magnetic distribution that acts on the magnetic detection unit (11) and processing of an index representing a degree of a positional change of the center position when a vehicle (5) passes over the magnetic markers (10) to determine a possibility of the presence of magnetic generation sources that causes disturbance, thereby suppressing erroneous detection of the magnetic markers (10).

Abstract: Provided is an assist apparatus for a vehicle leaving a parking space, including an automatic leaving execution unit configured to execute automatic leaving by automatic travel control mode of the vehicle and a switching control unit configured to switch driving of the vehicle from the automatic travel control mode to driver's driving operation mode, in which a state of the vehicle is determined and whether or not to perform a predetermined automatic travel control before switching the drive of the vehicle to the driver's driving operation mode is determined based on the determination result of the state of the vehicle.
