<p>PURPOSE: To provide a three-dimensional graphic recognition method which easily recognizes a general stsreo pattern as three-dimensional graphic by adding restrictive conditions at the time of recognizing three-dimensional graphics plotted on a two-dimensional face. CONSTITUTION: In this three-dimensional graphic recognition method which recognizes two-dimensionally expressed graphic data as three-dimensional graphics, sides and apexes of inputted two-dimensional graphic data are obtained by thinning (S201), and restrictive conditions for three-dimensional graphics are successively inputted (S200), and graphic data is recognized as three- dimensional graphics by the inputted restrictive conditions (S202). Restrictive conditions include fundamental restrictive conditions (S203) of the space coordinate system and the whole of graphics and supplementary partial restrictive conditions (S204).</p> |
