AI Overview
IMU sensor fusion calibration improves orientation and positioning accuracy by correcting systematic errors like
bias
,
scale factors
, and
axis misalignment
. Key techniques include
static calibration (recording data at rest), multi-position, and
6-axis rotation
to align with known gravitational or magnetic references
.
Online calibration
(e.g., EKF) continuously updates parameters to compensate for drift, with temperature modeling crucial for gyroscope stability.
Key IMU Calibration Techniques:
- Static/Multi-Position Calibration: Placing the sensor in multiple known orientations (e.g., 6 positions) helps determine accelerometer bias/scale factors by observing gravity's influence across axes.
