MATCHING COORDINATE SYSTEMS OF MULTIPLE MAPS, BASED ON TRAJECTORIES
A method for aligning digital maps, in particular by a control unit. Data of a first map present in a first coordinate system and data of a second map present in a second coordinate system are received. At least one trajectory within the first map and at least one trajectory within the second map are ascertained based on the received data. The data of the first coordinate system and the data of the second coordinate system are aligned with one another based on the respective trajectories. A transfer system, a control device, a computer program, and a machine-readable memory medium are also described.

MAP TILE OPTIMIZATION BASED ON TILE CONNECTIVITY
A system for vehicle navigation may include a processor including a circuitry and a memory. The memory may include instructions that when executed by the circuitry cause the processor to receive navigational information associated with the vehicle including an indicator of a location of the vehicle, and determine target navigational map segments to retrieve from a map database. The map database may include stored navigational map segments each corresponding to a real-world area. The determination of the target navigational map segments may be based on the indicator of vehicle location and on map segment connectivity information associated with the stored navigational map segments. The instructions may also cause the processor to initiate downloading of the target navigational map segments from the map database, and cause the vehicle to navigate along a target trajectory included in one or more of the target navigational map segments downloaded from the map database.
TRAVELING TRACK GENERATION DEVICE AND TRAVELING TRACK GENERATION METHOD
An entry point and an exit point are specified in a non-lane section. A lane definition line is searched to be continuous in a longitudinal direction of the road from the entry point to the exit point. A virtual lane marking line is generated to connect between the lane marking line on an entry side and the lane marking line on an exit side, based on the lane definition line detected as a search result. A travelling track is generated as a trajectory on which a vehicle is scheduled to travel, based on the virtual lane marking line.

Apparatus and associated methods for indicating road data gatherer upload zones
An apparatus comprising a processor and memory including computer program code, the memory and computer program code configured to, with the processor, enable the apparatus at least to: generate an indication of one or more communication network receiver upload zones for a road data gatherer along a planned route to be travelled by the road data gatherer, the indication determined according to a predetermined upload criterion, which takes account of the bandwidth capacities of communication network receivers along the planned route for the road data gatherer, to specify communication network receivers to be used by the road data gatherer for uploading of road data; and provide the indication to guide uploading of the road data gathered by the road data gatherer.
Localization of autonomous vehicles via ground image recognition
A system and method for localizing an autonomous vehicle using a digital stereo camera mounted to the autonomous vehicle and oriented to obtain images of the road surface. The system comprises an image processor configured to analyze the images of the road surface and identify micro-features, such as pores, holes, cracks, and granular material embedded in the street. The image processor is configured to compile previously obtained images of the road surface into reference mosaics and to compare the micro-features identified in newly obtained images to the reference mosaic to determine the location of the autonomous vehicle. The system may be further configured with a communications module to transmit images and localization information to a database repository or server.
Information providing apparatus, information providing system, and non-transitory computer readable medium storing program
An information providing apparatus includes an acquisition section that acquires position information from a terminal device, a specifying section that specifies a target publication from plural publications on which maps have been posted, by performing processing with the position information, and a providing section that provides the terminal device with information indicating a correspondence relationship between a map posted on the target publication and a position indicated by the position information.
Method, apparatus, and system for generating vehicle paths in a limited graph area
An approach is provided for generating/breaking vehicle paths on a limited graph area. The approach, for example, determining an expected frequency of location data collected from a sensor of a vehicle traveling on a roadway, wherein the location data include a plurality of probe points that are time-sequenced. The approach also involves detecting an exit or an entry of the vehicle on the roadway based on comparing the expected frequency to an observed frequency of the location data on at least one portion of the roadway. The approach further involves initiating an identification, a creation, a breaking, or a combination thereof of a path constructed from the location data based on the detecting of the exit or the entry of the vehicle. The approach further involves providing the path as an output.
System and method for localization of traffic signs
Provided herein is a system and method of a vehicle. The system comprises one or more sensors, processors, maps, and a memory storing instructions that, when executed by the one or more processors, causes the system to perform: monitoring a location of the vehicle while driving; detecting a sign while the vehicle is driving; capturing, frame-by-frame, data of the sign until the sign disappears from a field of view of the sensor; synchronizing each frame of the data with the location of the vehicle; determining a location of the sign based on the frame-by-frame data; in response to determining, at a frame immediately before the sign disappears from the field of view of the sensor, that the vehicle is driving towards the sign, uploading the detected sign and the location of the sign onto the one or more maps; and implementing a driving action based on the sign.
