In this method, we use the Vertex-Dictionary. We make the Vertex-Dictionary by calculation from CAD data of object figure (these data are already known) and the position data of the point of view. This dictionary includes the data of position and relations of connect surface etc. about a vertex. We get the data of three-dimensional vertex by comparison the data of two-dimensional intersection point in image data and Vertex-Dictionary. And we get the three-dimensional object by reasoning about the information of circumstances of all vertexes. Then we can recognize the three-dimensional object from image data. In this report, we explain the process to calculate the Vertex-Dictionary and some examples about this method. en-copyright= kn-copyright= en-aut-name=YamadaMitsuru en-aut-sei=Yamada en-aut-mei=Mitsuru kn-aut-name=山田充 kn-aut-sei=山田 kn-aut-mei=充 aut-affil-num=1 ORCID= en-aut-name=OsakiHirokazu en-aut-sei=Osaki en-aut-mei=Hirokazu kn-aut-name=大崎紘一 kn-aut-sei=大崎 kn-aut-mei=紘一 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Department of Systems Engineering affil-num=2 en-affil= kn-affil=Department of Systems Engineering END
