An improved method(IODSRA)to measure omni-direstional spatial rotation angles is proposed to focus on the problem
that the analytical approach for measurement of spatial angle with dual-axis inclination sensor can't measure the omni-directional rotation angle. It is based on the space model that measurement axis of inclination sensor rotates around measurement axis of rigid body
and the method improves the sensitivity of measuring angles and obtains spatial position parameters by applying a single axis inclinometer in the direction of normal vector of existed sensor. The optimal rotational angle measurement is acquired by taking full advantage of several rotation equations. Experimental results show that the IODSRA method achieves the measurement of the omni-directional spatial rotation angle while other algorithms are unable
and that detection accuracy can be controlled under 0.2° and meets requirements.
