摘要:
One or more systems, devices, and/or methods for generating a map including path side data include storing path side data referenced to three-dimensional geographic coordinates. The path side data may be optical data or optical data modified based on one or more panoramic images. The path side data is combined with map data received from a map database. The map data includes nodes and segments. A processor rotates the path side data based on one of the segments. The rotation may be about the segment or about a featured identified in the optical data. The path side data overlaid on the map data is outputted to a display, a file, or another device.

Disclosed are a system and method for creating multi-angle views of an object-of-interest from images stored in a dataset. A user specifies the location of an object-of-interest. As the user virtually navigates through the locality represented by the image dataset, his current virtual position is determined. Using the user's virtual position and the location of the object-of-interest, images in the image dataset are selected and interpolated or stitched together, if necessary, to present to the user a view from his current virtual position looking toward the object-of-interest. The object-of-interest remains in the view no matter where the user virtually travels. From the same image dataset, another user can select a different object-of-interest and virtually navigate in a similar manner, with his own object-of-interest always in view. The object-of-interest also can be “virtual,” added by computer-animation techniques to the image dataset. For some image datasets, the user can virtually navigate through time as well as through space.

Methods and apparatuses are provided for generating, using, and storing ambiguity ratings for map matching. In an embodiment, an ambiguity rating is generated using a road segment and a relationship of the road segment and other nearby road segments. The ambiguity rating may be stored in a cell based map. The ambiguity rating may be used to select an efficient map matching algorithm and provide expected map matching confidence.

One or more systems, devices, and/or methods for illustrating depth are disclosed. For example, a method includes receiving a depthmap generated from an optical distancing system. The depthmap includes depth data for each of a plurality of points, which are correlated to pixels of an image. Data indicative of a location on the image is received. Depth data correlated with the first point is compared to depth data correlated with pixels at surrounding points in the image. If the depth data correlated with the first point indicate a lesser distance from a viewer perspective of the image than the depth data of a pixel at the surrounding points in the image, the pixel is changed to a predetermined value. The comparison may be repeated at other pixels and a depth illustration may be drawn that relates the depth of the received location to other objects in the image.

Systems, apparatuses, and methods are provided for developing a fingerprint database for and determining the geographic location of an end-user device (e.g., vehicle, mobile phone, smart watch, etc.) with the database. A fingerprint database may be developed by receiving a depth map for a location in a path network, and then identifying physical structures within the depth map. The depth map may be divided, at each physical structure, into one or more horizontal planes at one or more elevations from a road level. Two-dimensional feature geometries may be extracted from the horizontal planes. At least a portion of the extracted feature geometries may be encoded into the fingerprint database.
