ACCELERATION MEASURING DEVICE |
摘要 |
The present invention relates to an acceleration measuring device capable of acquiring the offset or both of the sensitivity and the offset necessary for correcting the output of a triaxial acceleration sensor. The invention is provided with an acceleration sensor 1 for detecting the acceleration in a triaxial direction, a data acquisition portion 5A for acquiring the triaxial output data, a data selecting portion 13 for judging whether repeatedly acquired triaxial output data are appropriate to make a selection, a data accumulating portion 14 for accumulating the thus selected triaxial output data, a reference point estimating portion 15 estimating coordinate values of the reference point determined in the three-dimensional cartesian space by referring to the distribution of a predetermined number of accumulated triaxial output data in a three-dimensional cartesian space when each axial component is given as a coordinate value, and an offset correction/calculation portion 17 for correcting the offset of the triaxial output data of the acceleration sensor 1 on the basis of coordinate values of the reference point. |
