Abstract
A system and method for measuring rotational motion of devices such as cameras. A pair of linear accelerometers is attached to a camera. The accelerometers are spaced a fixed distance apart about a rotational axis to form an angular accelerometer. The angular accelerometer is used to measure the rotational acceleration about an axis of interest. The measured angular acceleration is integrated to calculate angular displacement about the axis. The angular displacement may be used to process camera images. For example, a camera image may be corrected for certain movements of the camera, such as rotations about a yaw or pitch axis.
