Abstract

A string arrangement device includes: a character string arrangement data acquisition unit for acquiring character string arrangement data for arranging a character string along a road; a control point sequence creation unit for creating a control point sequence from a road node sequence included in the character string arrangement data acquired by the character string arrangement data acquisition unit; a curve approximation unit for creating a node sequence obtained by approximating with a straight line a curve from the control point sequence created by the control point sequence creation unit; a curve approximation node sequence storage unit for storing the node sequence created by the curve approximation unit as a curve approximation node sequence; and a character string arrangement processing unit for performing arrangement processing of the character string based on the curve approximation node sequence stored in the curve approximation node sequence storage unit.

Description

technical field [0001] The present invention relates to a character string arranging device for arranging character strings such as road names on a map. Background technique [0002] Conventionally, there is known a car navigation system equipped with a character string arrangement function that arranges a character string such as a road name from a node (hereinafter referred to as an "arrangement start node") where character string arrangement starts (hereinafter referred to as "arrangement start node"). A function of arranging character strings along road lines (hereinafter referred to as “road node columns”) (for example, refer to Patent Document 1 to Patent Document 3). If you use this character string configuration function, characters are placed parallel to the road, so when you configure a character string spanning 2 lines (links), the angle of the road link changes (hereinafter referred to as "road angle change") and Changes in the placement angles of characters (he...
