A method of operation of a navigation system comprising: receiving multiple frames, including a first frame and a second frame, of images; detecting a traffic sign from the images between the first frame and the second frame based on a sign recognition model; extracting a first image from the first frame and a second image from the second frame; matching the traffic sign is the same in the first image and the second image based on a similarity model; generating a sign location of the traffic sign with an inertial measurement unit reading based on the first image and the second image; and generating a global coordinate for the sign location for displaying on a navigation map.

A tour group member gathering device includes a processing unit, an interface unit, a communication unit, and a map unit. The processing unit is connected to all units and controls all units accordingly. When the processing unit receives tour group member location information from the communication unit, the processing unit marks a current location and a tour group member location on map information generated by the map unit according to current location information and the tour group member location information. When marked event information is generated by the interface unit, the processing unit also generates a marked event location and a marked event message on the map information according to the marked event information. As the map information, the marked event information and the current location are displayed through the interface unit, a tour group member is able to effectively locate and communicate with other members of the tour group.

Provided are methods, systems, devices, and tangible non-transitory computer readable media for providing data including vehicle map service data. The disclosed technology can perform operations including receiving vehicle map service data from a plurality of service systems that include a plurality of client systems associated with a vehicle. The vehicle map service data can include information associated with a geographic area. A local map of the geographic area within a predetermined distance of the vehicle can be generated based on the vehicle map service data. Portions of the local map to which each client system is subscribed can be determined for each client system of the plurality of client systems. Additionally, the portions of the local map to which each client system is subscribed can be sent to a respective client system of the plurality of client systems.

Systems and methods for aggregating and integrating distributed grid element inputs are disclosed. A data platform is provided for a distribution power grid. The data platform provides a crowd-sourced gaming system for identifying grid elements and determining dynamic electric power topology. The data platform also provides an interactive interface for displaying a view of a certain area with identified grid elements. The data platform communicatively connects to the identified grid elements, collects data from the identified grid elements, and manages the distribution power grid.

A method is provided for a navigation device to display maneuvering instructions along a route, involving: displaying a digital map in a perspective manner on a display unit of the navigation device; according to the distance of the navigation device from the location of the maneuver, i.e. the location where a maneuver is to be carried out as per the route: displaying first maneuvering instructions for the maneuver when the navigation device is farther from the location of the maneuver than a predefined distance; displaying second maneuvering instructions instead of the first maneuvering instructions for the maneuver when the navigation device is closer to the location of the maneuver than the predefined distance; the first and second maneuvering instructions being displayed in such a way as to cover up a portion of the displayed digital map; displaying a graphic link between the location of the maneuver on the digital map and the first or second maneuvering instructions.

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.

Methods, apparatus, and database management systems are disclosed for providing, organizing, and present database search results and, more specifically, systems and methods for a chronological-based search engine. One method includes presenting live image data being captured by a camera of the end-user device. The method also includes determining a pose of the end-user device. The pose including a location of the end-user device. Additionally, the method includes sending the pose of the end-user device to an augmented reality platform entity and receiving closed captioning data from the augmented reality platform entity. The closed captioning data is based on the location of the end-user device and includes indications of first topics within the closed captioning data. The method includes superimposing the closed captioning data onto the live image data.

Aspects of the disclosure relate generally to generating and providing route options for an autonomous vehicle. For example, a user may identify a destination, and in response the vehicle's computer may provide routing options to the user. The routing options may be based on typical navigating considerations such as the total travel time, travel distance, fuel economy, etc. Each routing option may include not only an estimated total time, but also information regarding whether and which portions of the route may be maneuvered under the control of the vehicle alone (fully autonomous), a combination of the vehicle and the driver (semiautonomous), or the driver alone. The time of the longest stretch of driving associated with the autonomous mode as well as map information indicating portions of the routes associated with the type of maneuvering control may also be provided.

A method of automatic labeling of images for supervised machine learning includes obtaining images of roadside objects with a camera mounted to a vehicle, recording a position and orientation of the vehicle within a defined coordinate system while obtaining the images recording position information for each roadside object with the same defined coordinates system as used while recording the position and orientation of the vehicle, and correlating a position of each of the obtained images of the roadside objects with the position information of each roadside object in view of the recorded position and orientation of the vehicle. The images are labeled to identify the roadside objects in view of the correlated position of each of the obtained images of the roadside objects.

In some implementations, a computing device can provide a map application providing a representation of a physical structure of venues (e.g., shopping centers, airports) identified by the application. In addition, the application can provide an inside view that includes the physical layout and geometry of the venue's structure as well as the location, structure and layout of points of interest (e.g., stores, security check points, restrooms) within the venue. The views become more detailed as the user zooms into the venue to reveal points of interest and to give the user a feel for traversing the venue.
