Abstract: A vehicle trajectory prediction device is provided. The vehicle trajectory prediction device includes a transceiver, at least one processor, and at least one memory operatively connected with the at least one processor to store at least one instruction causing the at least one processor to perform operations. The operations receive first trajectory data for an ego-vehicle and second trajectory data for at least one neighbor-vehicle, obtain a first feature vector from a first extractor and obtain a second feature vector from a second extractor, obtain an interdependency feature vector between the ego-vehicle and the at least one neighbor-vehicle from a third extractor having mapping data generated by mapping the second feature vector to the second trajectory data as input data, and generate predicted trajectory data of the ego-vehicle from a trajectory generator having the first feature vector and the interdependency feature vector as input data.

Abstract: Systems and methods are disclosed for creating a magnetic map by obtaining magnetic field measurements from a plurality of platforms. A first set of poses for each platform is determined and information from the magnetic map is obtained for any existing magnetic field values for the first set. Magnetic constraints on poses of the platform are determined and used for determining a second set of poses for each platform. The magnetic field values of the magnetic map are then updated based at least in part on the second set of poses for each platform.

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; aligning and concatenating the trajectories to generate concatenated, aligned geospatial observations; performing attentional clustering on the concatenated, aligned geospatial observations to obtain a set of entities; processing the set of entities using one or more Set Transformers; generating a preliminary feature set of map object geometries; determining a number of output entities from each of the one or more output heads based on statistics from the plurality of sequences of geospatial observations from the discrete trajectories and a count of the discrete trajectories; and outputting a feature set, the feature set including a number of map object geometries corresponding to a respective number of output entities for the respective output head.

Abstract: In some aspects, a device may receive sensor data associated with a vehicle and a set of frames. The device may aggregate, using a first pose, the sensor data associated with the set of frames to generate an aggregated frame, wherein the aggregated frame is associated with a set of cells. The device may obtain an indication of a respective occupancy label for each cell from the set of cells, wherein the respective occupancy label includes a first occupancy label or a second occupancy label, and wherein a subset of cells from the set of cells are associated with the first occupancy label. The device may train, using data associated with the aggregated frame, a machine learning model to generate an occupancy grid, based on a loss function that only calculates a loss for respective cells from the subset of cells. Numerous other aspects are described.

Abstract: A method, apparatus and computer program product are provided in order to provide at least approximate real-time intelligent gap placement within mobility data using junctions inferred by features of the mobility data. In this regard, a data chunk associated with a sequence of location probe data points representative of travel of a vehicle along a portion of a road network is received. Additionally, junction behavior in the data chunk is identified based on one or more features for the sequence of location probe data points. Based on a status of a previous data chunk and a junction point that corresponds to a location probe data point immediately after a last probe data point in the junction, a gap placement or a sub-trajectory is applied in the sequence of location probe data points to generate at least a first subsequence and second subsequence of the location probe data points.

Abstract: A vehicle data collection system includes a vehicle-mounted sensor; a non-transitory computer readable medium configured to store instructions; and a processor connected to the non-transitory computer readable medium. The processor is configured to execute the instructions for generating an invariant feature map, using a first neural network; and comparing the invariant feature map to template data to determine a similarity between the invariant feature map and the template data, wherein the template data is received from a server. The processor is further configured to execute the instructions for determining whether the determined similarity is exceeds a predetermined threshold; and instructing a transmitter to send the sensor data to the server in response to a determination that the determined similarity exceeds the predetermined threshold.

Abstract: Generating first map information, where the first map information includes information about a first reference object set, and the information about the first reference object set indicates a first identifier, in a geographic area, of each reference object in at least one reference object included in the first reference object set, and indicates a first position of each reference object in the at least one reference object. The first map information is generated, and the first map information indicates related information of each reference object in the first reference object set, to implement a manner of expressing the related information of the reference object more abundantly, so that maps provided by different map vendors may use reference objects in the first map information to perform position expression on an element or an event.
