1. A system comprising:
a sensor configured to attach to an anatomy of a patient and comprising:
an optical sensor to generate optical measurements of a target configured to provide positional information to the optical sensor; and
an inclination measuring sensor to generate inclination measurements; and
an intra-operative computing unit in communication with the sensor, the intra-operative computing unit configured to:
receive the optical measurements representing positional information of the target;
determine surgical measurements during a procedure using the positional information;
receive inclination measurements from the inclination measuring sensor;
determine a direction of gravity from the inclination measurements;
output the surgical measurements and the direction of gravity.
