Patent ID: 6965397

Claim:
A system for using attitude sensors with a camera, said camera being part of a camera assembly, said camera assembly including a fixed portion and a movable portion, said system comprising: a first sensor coupled to said camera assembly, said first sensor measures movement of said movable portion relative to said fixed portion; and a first inclinometer coupled to said camera assembly, said first inclinometer measures an angle of a first axis of said fixed portion of said camera assembly, said measured angle including an actual angle component attributable to a gravitational force on said first inclinometer and an error component attributable to an acceleration force on said first inclinometer; a first gyro coupled to said camera assembly, said first gyro measures a relative angular change of said first axis, said measured relative angular change including an actual relative angular change component substantially equal to said actual angle component of said angle measured by said first inclinometer and an error component attributable to at least one of offset and drift of said first gyro; circuitry adapted to receive said measured angle and said measured relative angular change, said circuitry combines said measured angle and said measured relative angular change to remove said error component of said measured angle and said error component of said measured relative angular change in order to determine a value of said actual relative angular change component.
