ORIENTATION MEASUREMENT OF AN OBJECT

摘要

There is provided an object orientation measurement system for improving the accuracy of a first estimate of the orientation of an object to which the system is attached, the system comprising an accelero meter for measuring a first acceleration of the object; and an estimation unit for providing a position or velocity of the object; processing means for comparing the first acceleration and output of the estimation unit to form a correction signal, and for applying the correction signal to the first estimate of the orientation of the object to produce a second estimate of the orientation of the object.
