doubleFitAllanAcc::getBiasInstability()const{returnfindMinNum(calcSimDeviation(m_taus));}doubleFitAllanAcc::getWhiteNoise()const{returnsqrt(freq)*sqrt(calcSigma2(Q,N,B,K,R,1));} 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。
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...

Is it that these types of noise are "empirically observed" to most dominant in Allan Variance plot at these cluster interval values? How often and when we have to calibrate IMU and calculate gyro and accel white noise and random walk (if we are flying drone in different temperature ...
