ltan Geschrieben May 19, 2020 at 13:33 Share Geschrieben May 19, 2020 at 13:33 (bearbeitet) Hi, I am currently testing an IMU brick v2 and it seems that there is some offset (around 12 degrees) in the initial pitch angle. When the imu managed to correct its orientation, I tried to use the 'save calibration' function in brickv but the change was not saved. Everytime the imu is powered off, the offset will come back. The firmware version of the brick is 2.0.14. What should I do to correct the calibration? Thanks in advance, Leonardo Tan bearbeitet May 25, 2020 at 08:59 von ltan Zitieren Link zu diesem Kommentar Share on other sites More sharing options...

Such a bias cannot be removed with one-time calibration. You can accept the randomness of the sensor loosing some accuracy or calibrate the sensor every time you power it on. Alternatively you can implement algorithms that consider stochastic phenomena such as a Kalman Filter. Cheers. Zitieren Link zu diesem Kommentar Share on other sites More sharing options...
