Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0042]

[0043] First, the configuration of a map information processing device according to an embodiment of the present invention will be described.

[0044] figure 1 It is a block diagram showing an example of the configuration of the map information processing device according to the embodiment of the present invention. Such as figure 1 As shown, the map information processing device of this embodiment includes an input unit 1 , a position detection unit 2 , a map information storage unit 3 , a processor 4 , a display unit 5 , and an audio output unit 6 described below.

[0045] The input unit 1 is an operation switch group that transmits an instruction signal to the processor 4 based on a user's operation or instruction, and functions as an input unit.

[0046] The position detection unit 2 functions as a position detection unit that detects a position using, for examp...

Abstract

The purpose of the invention is to enable a reduction in time needed for a process that traces a road network. A map information processing device stores road network data in a map information storage unit (3). Said road network data is stored as information that indicates a connection relationship between a node defining the road network and a link. Said road network data comprises connection link information, which contains: information about the link, which is connected to the node; and information about a mesh to which the link belongs. On the basis of the connection link information, a processor (4) finds and stores in memory, neighboring node information that indicates a neighboring node, which is a node connected from a specified node via one link. After finding the neighboring node information of all the neighboring nodes for all the nodes contained in the acquired road network data, the processor (4) perform a process on map information using the road network data and the neighboring node information.

Description

technical field [0001] The present invention relates to a map information processing device, and more particularly to a map information processing device that performs map information processing including map matching processing and route search processing based on map data. Background technique [0002] In a typical map information processing device, map data includes road network information including node information indicating specific points such as intersections and link information indicating roads between the nodes. The map data is divided into grids (units) each divided into rectangles, and stored in the map data storage unit. [0003] Existing map information processing devices combine the connection information (one-side connection information) representing the connection relationship from a link to a node (or from a node to a link) and from a node to a link (or from a link to a node) The connection information (connection information on the other side) of the co...
