Method and system for determining segment types in figure represented by straight short vectors.

摘要

When straight short vectors representing a predetermined figure are given, a connecting point determination section (11) determines a connection state of a connecting point of each straight short vector. In accordance with the determination result, an attribute information setting section (12) sets attribute information for each connecting point. On the basis of the set attribute information, a segment type determination section (13) determines the segment type of each straight short vector. In this manner, the straight short vectors are classified into straight and curve segments. Curve fitting can be performed for the curve segments.
