    Abstract: A method of updating a digital road map which contains spatially resolved description values of at least one mapped environmental characteristic for at least one mapped road. A virtual journey along the at least one mapped road may be simulated, on basis of the road map to be updated, by a processor circuit before the updating process. The road map may be used to determine, for different virtual geopositions, an associated virtual measurement value of the at least one mapped environmental characteristic The virtual measurement values may be used to generate, for the virtual geopositions, a concatenated data record which describes the virtual journey. Newly received concatenated data records of real journeys of measuring motor vehicles and the concatenated data records of the virtual journey may be combined. The updated road map may be calculated from the combined received concatenated data records of real journeys and the virtual concatenated record.--

    Abstract: A map reliability determination apparatus includes a microprocessor and a memory coupled to the microprocessor. The microprocessor is configured to perform: acquiring a traveling trajectory of a predetermined section on which a subject vehicle has traveled; recognizing, based on a map information around the subject vehicle, a pair of left and right lane boundary lines which defines a lane on which the subject vehicle has traveled in the predetermined section; calculating a deviation amount between the traveling trajectory acquired in the acquiring and the pair of left and right lane boundary lines recognized in the recognizing; determining a reliability of the pair of left and right lane boundary lines recognized in the recognizing based on the deviation amount calculated in the calculating; and outputting the reliability information including a determination result of the reliability in the determining.

    Abstract: A map generation apparatus including a division line detection part, a feature point detection part and a microprocessor. The microprocessor is configured to perform generating a first map including position information of the division line detected by the division line detection part, generating a second map including position information of the feature points detected by the feature point detection part, and determining whether a position of the division line has changed, the determining including determining that the position of the division line has changed when a degree of difference between two first maps respectively generated at a first time point and a second time point after the first time point is a first predetermined degree or more and a degree of difference between two second maps respectively generated at the first time point and the second time point is a second predetermined degree or more.

    Abstract: A method, apparatus and computer program product are provided for learning to generate maps from raw geospatial observations from sensors traveling within an environment. Methods may include: receiving a plurality of sequences of geospatial observations from discrete trajectories; refining a summary entity set representation through iteration over discrete trajectories; determining a drive offset for each of the discrete trajectories based on a comparison of the summary entity set representation to a drive entity set for each of the discrete trajectories; aligning the discrete trajectories to generate aligned geospatial observations based, at least in part, on the drive offset for a respective discrete trajectory; concatenating the aligned geospatial observations; processing the concatenated, aligned geospatial observations using at least one Set Transformer; and generating, from the at least one Set Transformer, map geometries including objects from the geospatial observations.

    Abstract: A traveling body includes a range sensor and circuitry. The range sensor is disposed on a front face of the traveling body in a traveling direction in which the traveling body travels on a road surface and disposed obliquely downward at an inclination angle relative to the road surface. The circuitry determines presence of a continuous obstacle in a case where measurement results of a plurality of planes scanned by the range sensor include a plurality of feature values indicating unevenness relative to the road surface similar to each other. The circuitry generates an obstacle map of a front region of the traveling body not scanned by the range sensor, based on sequential feature information indicating that a predetermined number of feature values indicating the unevenness are sequentially present and controls the traveling body to travel on the road surface based on the obstacle map.
