Abstract
A method for fabrication of a composite structure including providing a mold configured for forming a composite structure, providing at least one magnetic anchor, the at least one magnetic anchor disposed within the mold, providing at least one optical marker, the optical marker magnetically coupled to the at least one magnetic anchor, providing an optical projector, the optical projector projecting at least one optical beam directed towards at least one optical marker, receiving at least one reflective beam from the at least one optical projector to identify the location of the optical marker disposed on the mold, calibrating the optical projector by comparing a predetermined virtual optical marker location to the identified optical marker location.
