An information terminal transmits present position information and acceleration information to a server device. The server device receives the present position information and the acceleration information of the information terminal, generates congestion prediction degree using the acceleration information, associates the congestion prediction degree with map data such that the congestion prediction degree can be displayed on a road map, and transmits association information indicating the association. The information terminal displays the congestion prediction degree on the road map on the display device using the association information transmitted from the server device.

The application concerns a method for creating maps in an automatic manner using sub-maps created randomly and combined by statistical accumulation. The measurements from information sensors, positioned on mobile platforms, are sent to reception means disposed randomly and independent of each other and transmitting the received information to a random computer processing layer. The random processing layer, creates within same random sub-maps as the information received by the computer network becomes available, the random sub-maps being dispersed arbitrarily in the random processing layer, access pointers being associated with the random sub-maps in order to make it possible to find them. An organising layer, using the access pointers, carries out the statistical recombination of the random sub-maps dispersed in the random processing layer with a view to reconstructing the desired final map or maps. The method according to the application, in one of the applications of same, is particularly useful for the economical and swift creation of complex maps with very large coverage, as required to monitor a country, the resources of same or the economic activity thereof.

In accordance with an aspect of the present disclosure, there is provided a method of updating a high definition map. The method comprises, acquiring two-dimensional images at a plurality of different locations by using a camera mounted on a vehicle; checking a moving trajectory of the camera for acquiring the two-dimensional images; generating a local landmark map by estimating, based on surface information of a road in the high definition map, a three-dimensional position of a landmark for a lane marking around the moving trajectory of the camera; and updating the high definition map based on the local landmark map.

A route display method for display on a terminal apparatus comprises: acquiring starting point information indicating a starting point and destination information indicating a destination; generating route information indicating a route from the starting point to the destination, wherein the route information includes a plurality of passing points; extracting captured images corresponding to the plurality of the passing points from a database which stores the captured images in relation to corresponding image capturing locations respectively, wherein each of the image capturing locations is within a range from the each of the plurality of the passing points; and displaying the extracted captured images in association with a map image sequentially in an order from a first captured image corresponding to a first passing point closest to the starting point to a second captured image corresponding to a second passing point closest to the destination.

A super-resolution stereoscopic visualization processing system encompasses a base map database storing the 5 m-DEM base map, the 5 m-DEM mesh reading unit, a geographic-coordinates XYZ-point file, a plane-rectangular coordinate converter, a plane-rectangular XYZ-point file, a rasterization processor, a fine grid-cell memory, a smoothing processor, a smoothing image memory, a consideration-distance grid-number calculator, a red stereoscopic-visualization image generator, a red stereoscopic-visualization image memory, wherein a super-resolution red stereoscopic-visualization image of 5 m-DEM is obtained on a screen of a display.

A current position of a user can be estimated with high accuracy. A movability calculation unit 210 calculates, for each of a plurality of candidate routes, movability indicating the degree to which movement along the candidate route is possible, based on a movement cost that is calculated, the movement cost indicating the degree of difficulty in traveling along the candidate route by a movement means, an expected route movement time that is calculated, the expected route movement time being a time necessary to travel along the candidate route by the movement means, and a time taken to travel from a past position to a current position, and a current position estimation unit 220 estimates a candidate current position on the candidate route with the highest movability to be the current position of a user on a geographic network.

A virtual map displaying system for a location-based game wherein the game is progressed in a virtual world through the linking to the position of a user in the real world, comprising: a real map storing portion for storing real map information that includes geographical information in the real world and text information relating to the geographical information; a virtual display data generating portion for generating and displaying virtual display data by superimposing, on the real map information, virtual objects relating to virtual geographical information corresponding to the geographical information in the real world in accordance with the progress of the game; and a related information displaying portion for displaying on a block, so as to be visually recognizable, text information that relates to geographical information that corresponds to a display location of a virtual object.

A method for measuring and registering 3D coordinates has a 3D scanner measure a first collection of 3D coordinates of points from a first registration position. A 2D scanner collects horizontal 2D scan sets as 3D measuring device moves from first to second registration positions. A processor determines first and second translation values and a first rotation value based on collected 2D scan sets. 3D scanner measures a second collection of 3D coordinates of points from second registration position. Processor adjusts second collection of points relative to first collection of points based at least in part on first and second translation values and first rotation value. Processor identifies a correspondence among registration targets in first and second collection of 3D coordinates, and uses this correspondence to further adjust the relative position and orientation of first and second collection of 3D coordinates.

According to the present disclosure, an information processing apparatus including an imaging request unit (160) configured to issue a request for imaging capturing for updating an environmental map including image information, and an environmental map update unit (135) configured to update the environmental map on a basis of a captured image captured in accordance with the request for the image capturing is provided. With this configuration, an environmental map is updated on the basis of a captured image captured in accordance with a request for image capturing. Thus, it becomes possible to accurately update information regarding an environmental map, by a simple method.

A vehicle control system includes a control unit for vehicle control and a server which distributes map information to the control unit. The map information includes information on a first type of road whereby full or partial driving assistance of the vehicle is possible, and information on a second type whereby full or partial driving assistance of the vehicle are not possible. The server includes an output unit which transmits information on a second type of road existing in a predetermined range from a first type of road on which the vehicle is traveling, and such that the first and second types of road form a predetermined angle or less. The control unit includes a map management unit including information on the first and second types of road, and a vehicle control unit controlling the vehicle by using the information on the first and second types of road.
