Abstract: A computer includes a processor and a memory storing instructions executable by the processor to determine an estimated pose of a vehicle in a global reference frame having a first error and to determine an estimated second error based on a combination of the first error and a map error, in which the map error represents a difference between the estimated pose of the vehicle in the global reference frame and a corresponding estimated pose in a map-referenced frame. The stored instructions being additionally to predict a third error in a future map-referenced measurement frame based on the estimated second error and a motion model and to compute an update to the third error by combining the predicted third error with an accumulation of instantaneous vehicle position and heading errors obtained via a comparison between a camera-observed feature and a corresponding feature from a digital map.

Abstract: There is provided a method for producing a high-definition (HD) map. The method includes detecting an object of a road area from the aerial image, extracting a two-dimensional (2D) coordinate value of the detected object, calculating a three-dimensional (3D) coordinate value corresponding to the 2D coordinate value by projecting the extracted 2D coordinate value onto point cloud data that configures the MMS data, and generating an HD map showing a road area of the aerial image in three dimensions based on the calculated 3D coordinate value.

Abstract: Techniques related to generating map data explicitly indicating a total drivable surface, which may include multiple types of drivable surfaces, are described herein. For instance, a given portion of a map may include map data indicating a combination of various drivable surfaces, such as road segments, lane properties, intersections, parking areas, shoulders, driveways, etc. Examples include joining these different types of drivable surfaces into combined map data that explicitly indicates a total drivable surface, such as a perimeter boundary indicating or representing a transition from a drivable surface to a non-drivable surface. The map data indicating the total drivable surface may be searched to determine information related to a drivable surface boundary, such as location and type. This boundary information may be used in various contexts, such as when planning a trajectory or remotely controlling a vehicle.

Abstract: A method, apparatus and computer program product are provided for generating lane line attributions for point locations along a road boundary for use in localization, map building, and map healing. Methods may include: receiving a sequence of geospatial observations from a vehicle traveling along a road segment; identifying, within the sequence of geospatial observations, lane line marking observations; determining, from the lane line marking observations, discrete points along the lane line markings, where the discrete points along the lane line markings include end points of a respective lane line marking; establishing a location of the vehicle based, at least in part, on the discrete points along the lane line markings; and providing for at least one of navigational assistance or at least semi-autonomous vehicle control based on the location established.

Abstract: In a computer-implemented method of assessing driving performance using route scoring, driving data indicative of operation of a vehicle while the vehicle was driven on a driving route may be received. Road infrastructure data indicative of one or more features of the driving route may also be received. A route score for the driving route may be calculated using the road infrastructure data, and a driving performance score for a driver of the vehicle may be calculated using the driving data and the route score for the driving route. Data may be sent to a client device via a network to cause the client device to display the driving performance score and/or a ranking based on the driving performance score, and/or the driving performance score may be used to determine a risk rating for the driver of the vehicle.

Abstract: A method for locating a vehicle involves detecting an elevation profile of a roadway of the vehicle and in which image features on the roadway are detected as landmarks and are compared with landmarks stored on a digital map. A transformation of the detected and/or stored landmarks into a common perspective performed to compare the landmarks. The transformation is carried out based on model parameters of a parametric model of the elevation profile of the roadway and a parametric model of a vehicle inclination. The model parameters are determined by determining an expected elevation profile of the roadway from the parametric models of the elevation profile and the vehicle inclination and minimizing a difference between the expected elevation profile and the detected elevation profile by varying the model parameters.

Abstract: Provided herein are systems and methods for updating a map. Map data associated with a topology and sensor data corresponding to linear features on the topology are obtained and a key linear feature is identified in the linear features. The method further comprises generating an extension of the key linear feature and identifying a next link segment corresponding to a current link segment of the key linear feature. At least one intersection location between the extended key linear feature and a perpendicular from at least one of (i.) the current link segment or (ii.) the next link segment is determined. A new linear feature location is generated based on the current link segment, the at least one intersection location, and the map data. The map is updated based on the new linear feature location.
