【Abstract】 A new application of micro inertial measurement unit (MIMU) is put forward, namely the three-dimension position measurement with MIMU. In the paper, The method for three-dimension position measurement by MIMU is introduced in detail. Meanwhile, the corresponding algorithms are presented, including the extraction of angle velocity for gyros, the extraction of transition matrix, the calculation for three-dimension position and the solution of attitude angle. It is indicated through experiments that satisfying results can be obtained in this method with inertial measurement components and within a not very long time in measuring. This method has widely applying perspective in the on-line measurement and manufacturing of big complex workpieces.更多还原
