Methods and a system are described for prioritizing the upload of connected vehicle map data in a central mapping system. A central mapping unit includes a central server which receives and processes data uploads by priority order, from highest priority to lowest priority. The uploaded data is compared to central map data to determine whether the central map requires updating. When the central mapping unit determines that there is not enough information to update the central map in a region, a priority list is updated to give high priority to data collection in the region. The updated priority list is pushed to connected vehicles travelling in the region, which have external sensors for data collection in the surrounding environment. When a connected vehicle enters the region, its external sensors collect data regarding the region, which is uploaded to the central mapping unit with highest priority.

A traffic signal recognition device recognizes a traffic signal present around a vehicle. The device acquires a position of the vehicle, and acquires a position of the traffic signal registered in map data based on the acquired position of the vehicle. The device acquires a position of a lighting device detected using an image frame captured by an in-vehicle camera. The device determines whether the lighting device corresponds to the traffic signal based on a difference between the acquired position of the traffic signal and the acquired position of the lighting device.

Provided are a method for processing an image, an electronic device, a vehicle, a server, and a storage medium, which relate to a field of artificial intelligence technology, and in particular, to the fields of autonomous driving, intelligent transportation, and the like. The specific implementation scheme is as follows: sending at least one piece of image information to a server, the at least one piece of image information being collected by a vehicle during driving in a target area; acquiring a first mapping result generated by the server, the first mapping result including first environmental characteristic information in the target area; and storing the first mapping result as the map information of the target area, the map information of the target area being used for driving the autonomous driving of the vehicle in the target area.

Computer implemented methods and systems for deploying response vehicles based on a virtual environment. A server may obtain a virtual model of an overall region wherein the virtual model was generated based upon a plurality of images captured by a remote imaging vehicle. The server may then provide the virtual model to a user electronic device for rendering in a virtual environment. The server may then determine a target location within the overall region at which the response vehicle should be deployed and generate a route for the response vehicle to follow. The route may be based on damage indicated by the virtual model of the overall region. The server may then provide the route to the user electronic device and/or the response vehicle.

Methods and systems are provided for facilitating a download of a specific portion of a map onto a computing device based on information received from a location-aware service. Location information, a start date, and an end date associated with travel plans of a user are received from, for example, a location-aware application or service. A download time corresponding to when to download a map portion corresponding to the received location information is determined. At or prior to the download time, it is determined whether the map portion can be downloaded at that particular time based on one or more factors. If the map portion can be downloaded at that time, the map portion is downloaded to a device associated with the user. The map portion is then removed from the device associated with the user on or after the end date.

A system and a method for updating and sharing crossroad dynamic map data are disclosed. The method includes steps of receiving a detection information outputted from an on-vehicle detecting device, wherein the detection information includes a host-vehicle absolute coordinate, a host-vehicle course, a host-vehicle speed, a relative speed between an object and the host vehicle, and an initial relative coordinate between the object and the host vehicle; respectively performing matching procedures to the host-vehicle absolute coordinate and the initial relative coordinate by respectively adding estimated coordinate shifts to obtain a matched host-vehicle absolute coordinate and a matched relative coordinate; performing a coordinate rotation transformation to the matched relative coordinate to obtain a matched transformed coordinate; merging the matched host-vehicle absolute coordinate and the matched transformed coordinate into crossroad-section map data to form crossroad dynamic map data; and sharing the crossroad dynamic map data.

Methods, systems, devices, and tangible non-transitory computer readable media for surface detection and geolocation are provided. The disclosed technology can receive location request data associated with a request for a geographic location of a user device in an environment. Based on the location request data, images of segments of a surface of the environment can be accessed. The geographic location of the user device can be determined based on the segment signatures that match stored segment signatures respectively associated with stored geographic locations. The segment signatures can be based on the images of the segments of the surface of the environment. Map data including information associated with a geographic area can be accessed. Furthermore, indications can be generated and the indications can include information associated with the geographic location of the user device within the geographic area.
