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.

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 enable guidance to be given more understandably, depending on the guidance location.

Provision of an image recognizing unit for analyzing the state of a guidance object that serves as a landmark for a guidance location, through image recognition using an image captured for the direction forward of a vehicle; a guidance information generating unit for generating guidance information that includes a supplementary explanation regarding the state of the guidance object, depending on the result of the analysis; and an output processing unit for outputting the guidance information.

Disclosed are various embodiments for image assisted delivery. A computing device may receive a first image from a first client device and a second image from a second client device. The computing device match a location in the first image to a location in the second image. The computing device may subsequently determine a characteristic of a package in the second image and determine that the characteristic of the package corresponds to package information of an order. Then, the computing device may confirm a delivery of the package.

A method of positioning a vehicle (N) that is provided with an electronic processor unit (2) connected both to a nonoptical positioning device (3, 4) and to an optical device (5) for taking external images, the electronic processor unit (2) including a database of landmarks including at least the geographical position of each landmark and a descriptive element describing each landmark, the method comprising the steps of: estimating a first geographical position (P1e) for the vehicle (N) by means of the nonoptical positioning device (3, 4); from the database, preselecting landmarks having geographical positions situated within a predetermined radius around the first geographical position (P1e) of the vehicle (N); selecting the triplets that minimize geometrical errors; controlling the optical device (5) for taking external images to take images of the selected landmarks; selecting images in which the landmarks are indeed visible, identifying the landmarks in the images, and, from the images, measuring a relative or absolute bearing for each visible landmark; and determining a second geographical position (POraw or POc) for the vehicle (N) from the measured relative or absolute bearings, optionally while taking account of movement of the vehicle (N) while the images of the landmarks of the triplet were being taken.

Systems and methods for improved transitioning and updating of navigations modes for multi-modal transportation routes are presented. In one embodiment, a method is provided that includes receiving a transportation route, which may include a first segment and a second segment. A first interface associated with the first segment may be displayed and may include a visual indicator of a rate of progress. A predicted travel time may be predicted, based on the rate of progress, to a starting location of the second segment. The visual indicator may be updated based on a comparison of the predicted travel time to a start time of the second segment.

The disclosure relates to a vehicle positioning method and system for a fixed parking scenario. The method includes: a marker detection step of detecting markers and identifying a pair of markers; a pose matching step of performing pose matching based on vehicle position information and the pair of markers; a non-pose matching step of performing non-pose matching based on the pair of markers, to obtain latest vehicle position information; and a position update step of updating current vehicle position information based on the latest vehicle position information obtained in the pose matching step or the non-pose matching step.

A system includes a processor configured to receive imaging of an environment surrounding a user, captured by a user device. The processor is also configured to identify a plurality of non-user entities in the image. The processor is further configured to identify a user location relative to the non-user entities. The processor is also configured to generate a digital representation of the user location relative to the non-user entities and convey the digital representation to a vehicle requested by the user.

A method is disclosed for mitigating the risks associated with operating an autonomous or semi-autonomous vehicle by using calculated route traversal values to select less risky travel routes and/or modify vehicle operation. Various approaches to achieving this risk mitigation are presented. A computing device is configured to generate a database of route traversal values. This device may receive a variety of historical route traversal information, real-time vehicle information, and/or route information from one of more data sources and calculate a route traversal value for the associated driving route. Subsequently, the computing device may provide the associated route traversal value to other devices, such as a vehicle navigation device associated with the autonomous or semi-autonomous vehicle. An insurance company may use this information to help determine insurance premiums for autonomous or semi-autonomous vehicles by analyzing and/or mitigating the risk associated with operating those vehicles.
