A surface extraction method, a surface extractor and a program which can enhance extraction precision of the surface of an object. Right or wrong of a voxel constituting an object represented in a voxel space to be sectioned into latticelike voxels is investigated in units of voxel sequence, and the end of constituent voxels continuous in the voxel sequence is extracted as the surface of the object. Since a straight line sequence is employed as a unit and the intermediate portion of the constituent region continuous in the straight line sequence is neglected, wrong extraction of a nonconstituent region as the surface of the object can be avoided without investigating the same region twice even if the nonconstituent region exists in the object. |
