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 9):
A system for measuring an alignment of an imager, the system comprising:\n a pair of support mechanisms to produce a pure rolling motion of a body; an imager rigidly affixed to the body to capture a series of images of an imager calibration target over a range of body roll angles of the rolling body; a sensor to measure the roll angles of the rolling body with respect to a world coordinate frame as defined by the imager calibration target; and a processor to: simultaneously estimate alignment angles of the imager and misalignment angles associated with an orientation of the body; and estimate a rotational transform between an imager coordinate frame and a body coordinate frame based on the estimated alignment angles and misalignment angles, wherein the alignment angles comprise three rotation angles representing a transform between the body coordinate frame and the imager coordinate frame, and wherein the misalignment angles comprise two rotation angles representing a transform between a roll axis of the body and the world coordinate frame. wherein the body comprises a guided projectile containing the imager.
