热效应(thermal effect) 校准误差(Calibration Errors) 零偏(constant bias) 零偏也就是IMU传感器生产出来后就一直固定不变的偏移值,但在实际使用中零偏很容易补偿,例如在初始启动过程中利用几秒钟的静态数据求平均即可扣掉大部分。 角速度传感器零偏的单位为◦/h;加速度计零偏的单位为m/s2 。 2. 白噪声(Noise)...

3.Calibration ProcedureA. Static DetectorIMU 标定的准确性非常依赖于静止和运动时间间隔的准确区分,为了标定加速度计我们使用静止周期,标定陀螺仪我们使用两个静态周期之间的动态时间间隔。我们这里使用基于方差的静止检测器,对于时间周期长度秒,我们有加速度,然后我们计算标准差:我们通过比较方标准差是否大于某一阈值来...
