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, 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; and
perform a registration to register the anatomy of the patient in the intra-operative computing unit using the measurements for determining the direction of gravity and the first optical information.
