提出了一种消费类便携设备中陀螺传感器的实时标定方法。校准自动进行，无需外部设备或用户干预。多级约束，包括伪观测，加速度计和磁力计测量，准静态姿态更新，用于使该方法在自然用户运动下的可靠性和准确性。使用三星Galaxy S3和S4智能手机进行的行走测试表明，即使在具有挑战性的运动模式下（如摇摆和口袋），以及在具有频繁磁干扰的具有挑战性的室内环境中，该方法也能提供有希望的校准结果。
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. Multilevel constraints, including the pseudoobservations, 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 provided promising calibration results even under challenging motion modes, such as dangling and pocket, and in challenging indoor environments with frequent magnetic interferences.
