Step 1: constructing the RCS
Origin of coordinate is a minutia O¼(xo, yo, qo) picked up
from Mset minutia set.
The vertical axis is a line passing through the origin O and
orthogonal to the orientation of the origin minutia O.
The horizontal axis is a line passing through the origin O,
and it is orthogonal to the vertical axis, i.e., the horizontal
axis coincide with the orientation of O.
