Patent ID: 7961928

Claim:
A volumetric data connecting apparatus comprising: a reference point determining device for having an operator determine reference points A, B and C which are not on the same straight line on first volumetric data V; a connection points ab determining device for having the operator determine a connection point a corresponding to said reference point A and a connection point b corresponding to said reference point B on a second volumetric data v; an auxiliary lines rt displaying device for displaying a section fc of the second volumetric data v selected by the operator, a curve r which results from the crossing of said section fc and a spherical surface R having (the distance between the reference points AC)×(the distance between the connection points ab)÷(the distance between the reference points AB) as its radius and the connection point a as its center, and a curve t which results from the crossing of said section fc and a spherical surface T having (the distance between the reference points BC)×(the distance between the connection points ab)÷(the distance between the reference points AB) as its radius and the connection point b as its center; a connection point c determining device for having the operator determine a connection point c corresponding to said reference point C on said section fc; and a coordinate adjusting device for adjusting the coordinates of said first volumetric data V and said second volumetric data v such that said reference points A, B and C and said connection points a, b and c have respectively the same coordinates.
