Abstract: In one embodiment, navigational features of a navigation device are activated or deactivated according to the accuracy of the geographic data. The navigation features may be predictive features related to upcoming portions of a path curve. The path curve is compared to measured data. For example, a first curve is accessed from a map database and a second curve is based on measured position data collected while traversing the path. The first curve and the second curve correspond to the same geographic area. A difference of an attribute between a section of the first curve and a section of the second curve is used to assign a confidence factor to the section of the first polycurve based on the difference. The attribute may be heading, position, curvature, or another aspect of the path curves.

Abstract: A method, apparatus and computer program product are provided for generating map geometry based on a received image and probe data. A method is provided including receiving a first image and probe data associated with the first image, categorizing pixels of the first image based on the probe data, and generating a map geometry based on the pixel categorization of the first image.

Abstract: In one implementation, sets of probe data are collected by probe vehicles. The probe data describes the driving characteristics of the probe vehicles. The sets of probe data are sent to a server or a mobile device for analysis. A polycurve, including a piecewise function of map data, is modified based on the probe data. The polycurve may be a spline curve for an advanced driver assistance system. The modified polycurve may be used in the advanced driver assistance system for a vehicle traveling along the same path previously traversed by the probe vehicles. Based on the polycurve modified by the probe data, a driver assistance feature is provided to the vehicle.

Abstract: A method and system for using Bezier curves in vehicle positioning and electronic horizon applications for providing data to advanced driver assistance systems (ADAS) applications are disclosed. The Bezier curves are obtained from B-splines. The obtained Bezier curves are subdivided in a manner that allows the vehicle positioning application to derive a polyline representation in real time. Using the Bezier and polyline geometry, the vehicle positioning application provides a vehicle position approximation to the ADAS applications. Using the Bezier curves, the electronic horizon application provides curvature, slope, and heading profiles to the ADAS applications.

Abstract: Road geometries may be determined from sparse data by receiving mobile device data points comprising data indicating positions of vehicles having traveled on a roadway of a geographic area, the roadway involving a convergence or divergence of road branches for the roadway. At least one trajectory angle for a particular mobile device data point of the mobile device data points may be determined using at least one trajectory line connecting the particular mobile device data point to an adjacent mobile device data point, and mobile device data points may be grouped based on the trajectory angles.

Abstract: Road geometries may be determined from sparse data by identifying a set of mobile device data points generated by a mobile device located in a geographic area. Further, the data points may be connected with a curve comprising a series of splines defined by curve functions. The shape of the splines may be optimized by applying a scaling factor to the curve functions. A resulting optimized curve may be representative of a road in a geographic area.

Abstract: An approach is provided to process imaging data associated with location trace data of one or more links of a road. A processing platform may process and/or facilitate a processing of imaging data associated with location trace data of at least one link of a road to determine maneuvering information for at least one vehicle collecting the imaging data, the location trace data, or a combination thereof. Further, the processing platform may determine whether to cause, at least in part, an adjusting of at least a portion of the location trace data based, at least in part, on the maneuvering information.

Abstract: A method and system for creating geometry for ADAS are described. Link chains, which are a sequence of segments, are created. The link chains are used to create 2D splines. The link chains, the 2D splines, and height data are used to create 3D splines. The 3D splines and possibly the 2D splines are converted to Bezier curves, which can be used to create a 2D polyline. ADAS applications can use the Bezier curves and the 2D polylines to provide ADAS functions.

Abstract: In one embodiment, a mobile device generates sensor data configured to describe a geographic position of a mobile device. A list of events is defined according to position data and time data. The geographic position of the mobile device is compared to positions in the list of events of interest and a current time is compared to time data in the list of events of interest. The comparison determines whether events in the list are in range of the mobile device. One or more nearby events in range of the mobile device at the current time or a future time are selected. A command is generated to capture an image of the nearby events using a camera coupled to the mobile device. The captured images may be used to update navigation or map database, provide community or weather data to other users, social media functions, or other features.
