1. An automated registration method to align virtual coordinate systems, the method comprising:
capturing a first set of registration points from an anatomical surface of a patient using a first registration system;
capturing, concurrently with the capturing the first set of registration points, a second set of registration points from the anatomical surface using a second registration system, wherein the locations of the second set of registration points on the anatomical surface match the first set of registration points; and
calculating a transfer matrix based on at least a portion of the first set of registration points and the second set of registration points to align a first coordinate system with a second coordinate system.
