ABSTRACT:
A method and device for measuring a motion of a rigid body, using the least possible accelerometers that are simply arranged. One-axis uni-directional accelerometers 1 through 6 are each fixed to the rigid body through a base 12. Thus, no Coriolis force is developed even though an external force is applied thereto. The six one-axis uni-directional accelerometers 1 through 6 are mounted to three or more different positions relative to the rigid body. Consequently, a processing unit 21 can perform processing so that centrifugal and angular effects included in each one-axis uni-directional accelerometer may be separated. As the one-axis uni-directional accelerometers 1 through 6 are arranged on the same plane, you have only to consider two-dimensional positional relationship among the accelerometers for the accuracy of the arrangement thereof.
