Abstract:
A technique is provided to measure an alignment of an imaging device of a guided projectile containing an imager and a world coordinate frame, and includes producing a pure rolling motion of a body of the projectile, capturing a series of images of an imaging device calibration target over a range of body roll angles of the rolling body, measuring the roll angles of the rolling body with respect to a world coordinate frame as defined by the imaging device calibration target, simultaneously estimating alignment angles of the imaging device and misalignment angles associated with an orientation of the body, and estimating a rotational transform between an imaging device coordinate frame and a body coordinate frame based on the estimated alignment angles and misalignment angles.

Claim (Index 1):
A method for measuring an alignment of an imaging device, the method comprising:\n producing a pure rolling motion of a body; capturing a series of images of an imaging device calibration target over a range of body roll angles of the rolling body; measuring the roll angles of the rolling body with respect to a world coordinate frame as defined by the imaging device calibration target; simultaneously estimating alignment angles of the imaging device and misalignment angles associated with an orientation of the body; and estimating a rotational transform between an imaging device coordinate frame and a body coordinate frame based on the estimated alignment angles and misalignment angles wherein the producing of the pure rolling motion of the body occurs by a pair of support mechanisms that mechanically constrain the body to produce the pure rolling motion wherein the support mechanisms comprise v-block mechanisms.
