Claim 3:
4. The method of claim 3, wherein the determining of whether the respective directional representative voxels for the plurality of voxel groups satisfy planeness comprises:
for each of the directional representative voxels, selecting a first voxel that is a directional representative voxel having a same phi direction coordinate as the corresponding directional representative voxel and having a theta direction coordinate that is larger than that of the corresponding directional representative voxel, and a second voxel that is a directional representative voxel having a same phi direction coordinate as the corresponding directional representative voxel and having a theta direction coordinate that is smaller than that of the corresponding directional representative voxel, and determining whether the corresponding directional representative voxel satisfies a line fitting condition for a first straight line generated by a predetermined first rule in the theta direction;
selecting a third voxel that is a directional representative voxel having a same theta direction coordinate as the corresponding directional representative voxel and having a phi direction coordinate that is larger than that of the corresponding directional representative voxel, and a fourth voxel that is a directional representative voxel having a same theta direction coordinate as the corresponding directional representative voxel and having a phi direction coordinate smaller than that of the corresponding directional representative voxel, and determining whether the corresponding directional representative voxel satisfies a line fitting condition for a second straight line generated by a predetermined second rule in the phi direction; and
when the corresponding directional representative voxel satisfies the line fitting condition for the first straight line and the line fitting condition for the second straight line, determining that the corresponding directional representative voxel satisfies planeness.
