但是如果在这里加上一个仍然和真值有约一个 \sqrt{\Delta t} 的scale,因此标定imu的bias游走还是用kalibr_allan较为准确。下图是kalibr_allan的标定结果: 加速度计 陀螺仪 从图上可知,标定出来的结果和我们设定的真值差别不大,可以认为是标定正确的。
kalibr_allan直接在图中给出了标定结果: accelerometer_noise_density = 0.01931403 /设定值0.019 accelerometer_random_walk = 0.00060598 /设定值5e-4 gyroscope_noise_density =0.01538619 / 设定值0.015 gyroscope_random_walk = 0.00003262 / 设定值5-e5 简单对比一下,可以发现kalibr_allan的标定结果要比imu_utils...
