1. A system for determining a location of a plane in which an axis of an object is disposed, said system comprising:
(a) a first marker comprising a first area and a surface having two parallel edges and a third edge disposed perpendicularly to said two parallel edges, said two parallel edges are disposed about a first central axis of said two parallel edges; and
(b) a sensor configured to provide a distance from the sensor to a portion of said first marker,
wherein said sensor is adapted to obtain distances between said sensor and said first marker and an environment surrounding said first marker to form a first map representing the distances corresponding to locations from which the distances are obtained using said sensor and the location of the plane in which an axis of the object is disposed, is determined based on at least one corner corresponding to an intersection formed of said third edge and one of said two parallel edges.
