The processor is configured to acquire position information of a vehicle via the communication module, determine whether high definition (HD) map information corresponding to the position information is acquired, display three-dimensional (3D) navigation information in augmented reality by using the HD map information when the HD map information is acquired, and display two-dimensional (2D) navigation information in augmented reality when the HD map information is not acquired. The 3D navigation information is information in which virtual 3D graphic information for driving guidance is spatially matched to and displayed on an actual object in the real world by using the HD map information, and the 2D navigation information is information in which virtual 2D graphic information for driving guidance is planarly matched to and displayed on an actual object in the real world.

The present application discloses a method and apparatus for determining a route, a device and a computer storage medium, and relates to the field of big data. An implementation includes: acquiring route description information input by a user, and acquiring a route contour with the route description information; matching the route contour in road network data to obtain the route matched with the route contour, so as to generate recommended routes, wherein this operation specifically includes: extracting intersection points in the route contour, each of which is formed by intersecting at least two lines; selecting one of the intersection points, and querying the road network data using a corresponding angle sequence of the selected intersection point in the route contour, so as to obtain intersections matched with the selected intersection point as candidate intersections; traversing the candidate intersections, fixedly mapping the selected intersection point to the positions of the candidate intersections, equally scaling the route contour in the road network data, and recording mapped road information if all lines of the route contour are mapped onto connected roads; and generating the recommended routes with the recorded road information.

The present specification discloses a method for displaying an AR navigation screen, and an AR navigation system. The method for displaying an AR navigation screen according to the present specification may comprise the steps of: overlapping and displaying images of the surroundings of a vehicle and a plurality of AR images corresponding to the images of the surroundings; generating a window for separately displaying a first area including AR images overlapping at least one of the plurality of AR images; and overlapping and displaying the window and the images of the surroundings. The invention of the present specification has the effect of improving user convenience and promoting safe vehicle operation by using a window when AR images and the like are difficult to recognize due to being overlapped.

To more realistically represent the real-world, a street-level view depicts a route path and objects that occlude one or more segments of the route path. Such objects can include guardrails, buildings, or any of a variety of other objects as described herein. The street-level view can be implemented in advance to preview travel, during travel, or in other scenarios. The street-level view presents the route path from a viewpoint that can be a current location of a traveler or an arbitrary location.

A route from a current location of a portable device to a destination is determined, where the route includes a sequence of directed sections. Navigation instructions to guide a user of the portable device along the route to the destination are generated. To this end, candidate navigation landmarks perceptible within a 360-degree range of the current location of the portable device are identified, a navigation landmark disposed in a direction substantially opposite to the direction of the first one in the sequence of directed sections is selected from among the candidate navigation landmarks, and an initial instruction in the navigation instructions is generated and provided via a user interface of the portable device. The initial instruction references the selected navigation landmark.

A computer-implemented method includes: obtaining, by a user device, information defining a navigation path to a destination; and forming, by the user device, protrusions on a display of the user device, wherein a pattern of the protrusions corresponds to the navigation path.

A method and an apparatus are disclosed for providing navigation instructions. The method may include receiving, from a user apparatus, a first location and a destination location; calculating a first route from the first location to the destination location; generating, for a predetermined time period, a first set of maneuvering data corresponding to the first route, the first set of maneuvering data comprising playback cues based on a predicted user apparatus location; transmitting the first set of maneuvering data to the user apparatus; receiving, from the user apparatus, a second location; generating, for a subsequent predetermined time period, a second set of maneuvering data, the second set of maneuvering data comprising playback cues based on a further predicted user apparatus location; calculating an update set of maneuvering data based on the first and second set of maneuvering data; and transmitting the update set of maneuvering data to the user apparatus.

The present disclosure relates generally to identification of drivable surfaces in connection with autonomously performing various tasks at industrial work sites and, more particularly, to techniques for distinguishing drivable surfaces from non-drivable surfaces based on sensor data. A framework for the identification of drivable surfaces is provided for an autonomous machine to facilitate it to autonomously detect the presence of a drivable surface and to estimate, based on sensor data, attributes of the drivable surface such as road condition, road curvature, degree of inclination or declination, and the like. In certain embodiments, at least one camera image is processed to extract a set features from which surfaces and objects in a physical environment are identified, and to generate additional images for further processing. The additional images are combined with a 3D representation, derived from LIDAR or radar data, to generate an output representation indicating a drivable surface.

An operation method of a navigation apparatus includes: obtaining valid global positioning system (GPS) data at a current time point corresponding to a current position of a target device; determining first neighboring map elements corresponding to a first region indicated by the valid GPS data at the current time point from among a plurality of map elements of map data; and determining a pose parameter of the target device at the current time point based on a first direction specified by at least a portion of the first neighboring map elements.
