论文摘要
本文为消费者便携式设备中的陀螺仪传感器提供了一种实时校准方法。校准会自动进行，而无需外部设备或用户干预。多级约束，包括伪观察，加速度计和磁力计测量以及准静态态度更新，用于使方法在自然用户运动下可靠，准确。三星Galaxy S3和S4智能手机的步行测试表明，即使在诸如悬挂和口袋之类的具有挑战性的运动模式下，以及在具有频繁磁干扰的挑战性室内环境中，该方法估计有希望的校准结果。
This paper presents a real-time calibration method for gyro sensors in consumer portable devices. The calibration happens automatically without the need for external equipment or user intervention. Multi-level constraints, including the pseudo-observations, the accelerometer and magnetometer measurements, and the quasi-static attitude updates, are used to make the method reliable and accurate under natural user motions. Walking tests with the Samsung Galaxy S3 and S4 smartphones showed that the method estimate promising calibration results even under challenging motion modes such as dangling and pocket, and in challenging indoor environments with frequent magnetic interferences.
