Calibration - figure of eight
Opened this issue · 2 comments
I'm being a bit thick. My mpu9250 sensors look to be baldy calibrated and I'm wondering what I've done wrong. I read about the 'figure of eight' and am thinking 'wait....'. So silly question time: when moving the sensor in a figure of eight, do I keep it heading in the same direction keeping the yaw constant, or should I rotate it in the direction of travel, rotating through yaw? Should I be moving it flat on my desk, or vertically? Ok, that's two questions.
I might as well ask a third....when I flip the sensor through any axis, the reading take a long time to catch up. As in tens of seconds, not tenths of seconds.
Ok, a fourth, and final question. If I leave the sensor alone, I'm seeing pitch drift over time. Why might this be?
I'd really appreciate some pointers on this, thanks.
Ian.
