Abstract: An objective of the present invention is to provide a method for processing surrounding information which enables improvement of accuracy for estimation of a current position of a moving body. A current position of a moving body can be estimated with information after removal by acquiring surrounding information with a sensor in a surrounding information acquisition step, removing information of a feature including light transparent information from the surrounding information and thereby generating the information after removal. Here, the estimation accuracy can be improved by omitting the information about the light transparent region for which the acquired information may vary.

Abstract: A first onboard device-mounted on a measuring vehicle—includes a LiDAR, and it receives a reflected wave which is laser emitted to and reflected by a road surface and recognizes a curve start location of a lane line on the road surface based on reflected wave intensity. The first onboard device-transmits road surface information including the recognized curve start location to a server device via a network. The server device gives information indicating the curve start location to information regarding the lane line in map information based on the road surface information. A second onboard device mounted on a vehicle acquires the information regarding the lane line from the server device and estimates a current location by comparing a curve start location of the lane line recognized by a LiDAR and the information indicating the curve start location of the lane line acquired from the server device.

Abstract: An objective of the present invention is to provide a method for processing surrounding information which enables improvement of accuracy for estimation of a current position of a moving body. The objective is achieved by detecting light transparent region information of the surrounding information acquired by a sensor in a detection step, wherein the light transparent region information corresponds to a light transparent region. Further, in a generation step, information after removal is generated by removing the light transparent region information from the surrounding information. In this manner, a current position for a travelling vehicle can be estimated with the information after removal. The estimation accuracy can be improved by omitting the information about the light transparent region for which the acquired information may vary.

Abstract: A data generating apparatus includes an acquiring unit that acquires text data (name data) related to a name associated with position information; a classifying unit that using the acquired position data, classifies the name data according to given regions; an integrating unit that integrates neighboring regions such that the total data size of the name data included in regions to be integrated does not exceed a predetermined given data size; a storage unit that groups the name data according to integrated regions and stores the grouped name data as a name dictionary to be used in both a facility search process and a map display process; and an extracting unit that from the classified name data, extracts the name data common to regions of a given number or more, where the storage unit groups and stores the common name data as a common name dictionary different from the name dictionary.

Abstract: In a map data recording device (100), a setting section (104) sets a group by combining parcel data so that the total amount of data is within the upper limit value acquired by an upper limit data amount acquiring section (102) or the total number of pieces of data is within the upper limit number of pieces acquired by an upper limit number-of-pieces of data acquiring section (103). A compression section (105) then groups the parcel data for compression and a recording control section (106) records it on a recording section (101). Further, in a map display (110), a reading section (112) reads the parcel data in a group unit from the recording section (101) and extends the parcel data read by an extension section (113). A display control section (114) then controls a display section (111) and selects parcel data included in a display range from the extended parcel data to display it on the display section (111).

Abstract: A navigation apparatus, which is mounted on a movable body such as a vehicle, displays a map around a present position in plural display modes which a user can designate. The map data is prepared in each display mode to be stored in a storage unit. For example, the present position of the movable body is detected by a unit such as a GPS. Then, based on the present position, a base link which is used as a basis of a display mode change is determined. Basically, the map is displayed in the display mode designated by the user. However, when the map data corresponding to the display mode designated by the user does not include the base link, the map is displayed in the display mode corresponding to the map data including the base link. The base link can be a link corresponding to the present position of the vehicle, or a scheduled travel link on a guide route.
