A method for measuring optical distortion of an object, the method comprising: mapping an initial orientation and an initial position of each of a plurality of reference marks relative to a reference point, wherein the initial orientation includes an X, Y, Z location and elevation, azimuth and roll orientation of each reference mark relative to the origin of a reference coordinate frame; loading the initial orientation and the initial position of each of the plurality of reference marks into a recording device, wherein each of the plurality of reference marks is a fiducial; recording a first orientation and a first position of a plurality of reference marks relative to a pointing angle of a recording device, wherein the plurality of reference marks are located in an optical field of view of the recording device; disposing an object between the recording device and some of the plurality of reference marks, the object having been disposed outside the optical field of view of the recording device during the recording of the first orientation and the first position; recording a second orientation and a second position of the plurality of reference marks relative to the pointing angle of the recording device; and comparing the first orientation and the first position of the plurality of reference marks to the second orientation and the second position of the plurality of the reference marks for measuring distortion introduced by the object by calculating, for each of the plurality of reference marks, the difference between the first orientation and the first position of the reference mark and the second orientation and the second position of the reference mark, and using the differences to calculate the distortion introduced by the object. mapping an initial orientation and an initial position of each of a plurality of reference marks relative to a reference point, wherein the initial orientation includes an X, Y, Z location and elevation, azimuth and roll orientation of each reference mark relative to the origin of a reference coordinate frame; loading the initial orientation and the initial position of each of the plurality of reference marks into a recording device, wherein each of the plurality of reference marks is a fiducial; recording a first orientation and a first position of a plurality of reference marks relative to a pointing angle of a recording device, wherein the plurality of reference marks are located in an optical field of view of the recording device; disposing an object between the recording device and some of the plurality of reference marks, the object having been disposed outside the optical field of view of the recording device during the recording of the first orientation and the first position; recording a second orientation and a second position of the plurality of reference marks relative to the pointing angle of the recording device; and comparing the first orientation and the first position of the plurality of reference marks to the second orientation and the second position of the plurality of the reference marks for measuring distortion introduced by the object by calculating, for each of the plurality of reference marks, the difference between the first orientation and the first position of the reference mark and the second orientation and the second position of the reference mark, and using the differences to calculate the distortion introduced by the object.
