Hi!
When we fix camera to car and drive around our square building which has perfect corner angles (90 degrees each), then IMU has 2 corners value 90 degrees, but one 120 degree, other 60 degree. Probably compass (or IMU) needs to be calibrated on the same way like Android phone requires calibration/rotation. How we can do that calibration with some code or app so such IMU calibration would be stored on device and some other 3rd party software would use IMU with that calibration and all angles around our building would be more looking like 90 degrees…
