| 摘 要： | 针对微机械惯性测量单元的工程应用需求,提出了一种改进的现场标定方法.通过8个位置的选取,降低了配套设备的复杂程度,易于工程实现;由于8个位置的测量信息是6个位置测量信息的4倍,使得利用非线性最小二乘法拟合求取到的校准模型参数精度得以提高.

| Abstract: | A improved field-calibration method is proposed for meeting the application demand of MIMU By using a modified calibration model and choosing eight measuring positions,This method decrease the complexity of attaching equipment and is convenient to industrialization Account of the measurement information from 8 locations can be four times of that from 6 positions, in order to make full use of measurement information,we use nonlinear least square fitting model parameters As a result,the parameters precision is improved to satisfy the calibration precision. |
