Title: MAP DATA GENERATING DEVICE, TERMINAL DEVICE, AND MAP DATA GENERATING METHOD
Abstract:
The purpose of the present invention is to provide a technique by which it is possible to reduce the difference between a three-dimensional shape expressed by map data using approximation, and a three-dimensional shape of an actual object. Provided is a map data generating device that can generate map data that expresses a three-dimensional shape using approximation, the map data generating device being provided with the following: an acquisition unit that acquires a shape point array that indicates a three-dimensional shape; and a control unit that generates an arc passing through three target points on the basis of the three target points among the shape point array acquired by the acquisition unit, and determines whether an approximate separation point that should not be approximated in the three-dimensional shape is included among the three target points on the basis of the arc.
