SYSTEM AND METHOD FOR MEASURING TILT USING LOWEST DEGREES OF FREEDOM OF ACCELEROMETER

摘要

Systems and methods are provided for calculating the tilt of an object from a minimum set of measurements. In the described embodiments, one or more accelerometers are used to sense tilt in fewer degrees of freedom than would otherwise be required in a conventional measurement apparatus. In one embodiment, a single axis accelerometer measures 2D tilt by taking into account a constant value of the earth's gravitational field in a direction generally perpendicular to the earth.
