摘要:
An apparatus for displaying a travel path of a running body, such as a vehicle in which a constantly changing location of the running body is successively computed and the current location of said running body is displayed successively, in accordance with the data thus computed, on a display screen having a map previously displayed thereon, which comprises means for dividing patterns of roads on said map and the path of travel of the running body into line segments to effect pattern recognition according to the polygonal approximation and means for producing a display of the travel path in accordance with the line segments of the road to which the matching of the pattern recognition has been attained.
