1. A system for intra-operative surgical measurement and display of relative position of an object with respect to the anatomy of a patient comprising:
- a first sensor unit configured for coupling to a body part of the patient;
a second sensor unit configured for coupling to the object;
wherein at least one of the first sensor unit and the second sensor unit is configured to provide a signal representing position and an other of the first sensor unit and the second sensor unit comprises an optical sensor configured to receive the signal in a field of view aligned with a surgical site;
a processing component configured to;
receive sensor information from the optical sensor;
determine the relative position and display information in accordance with the sensor information; and
a display unit for receiving and presenting the display information.
