Claim 0:
1. A system comprising:
a sensor comprising an optical sensor configured to provide optical information, and a measuring sensor configured to provide measurements for determining a direction of gravity;
a first target configured to attach to an anatomy of a patient and configured to provide positional information in up to six degrees of freedom to the optical sensor;
a second target configured to attach in a known positional relationship to an object, the second target configured to provide positional information in up to six degrees of freedom to the optical sensor; and
an intra-operative computing unit configured to:
receive first optical information for the first target and second target, and measurements for determining the direction of gravity, wherein the first optical information and the measurements received from the sensor are for a registration step performed for a registration, the first optical information comprising information for the second target attached to a registration device to determine at least one axis relative to the anatomy;
receive second optical information for the first target and second target, the second optical information received from the sensor for a subsequent step of a surgical procedure, the second optical information comprising information for the second target attached to a bone of the anatomy of the patient, a surgical tool for the surgical procedure, or an implant for the surgical procedure; and
determine and present measurements relative to the anatomy for the surgical procedure, wherein the measurements relative to the anatomy are determined from the second optical information, and in relation to the registration of the anatomy of the patient.
