摘要
对MEMS惯性姿态模块中传感器的标定主要包括非正交误差标定和温度漂移误差标定。传统标定过程,人员通过操控转台,逐台完成标定,无法满足工程批量生产的需求。尤其是温度标定,人员需按温度变化,及时控制转台,长时间操作易出现疏忽导致标定结果偏差。设计了一种基于STM32F407的批量自动化标定系统,一次可自动标定八台产品,提高了效率,降低了成本。使用该系统标定后,姿态角精度从原先人工标定的1.8°提高至0.8°,惯性姿态模块的性能精度得到明显提高。
The calibration of sensors in MEMS inertial attitude module mainly includes non orthogonal error calibration and temperature drift error calibration. In the traditional calibration process, people operate the turntable and complete the calibration one by one, which can not meet the needs of mass production. Especially for temperature calibration, the personnel need to control the turntable in time according to the temperature change, which is easy to cause the calibration result deviation due to negligence during long-term operation. In this paper, a batch automatic calibration system based on STM32 f407 is designed, which can automatically calibrate eight products at a time, improving efficiency and reducing cost. After the system is calibrated, the accuracy of the attitude angle is improved from 1.8° to 0.8°, and the performance accuracy of the inertial attitude module is improved obviously.
