AI Overview
IMU calibration ensures accurate, drift-free sensor data by correcting for bias, scale factor, and misalignment errors. Key techniques include
static, multi-position (6 or 12-point), and temperature compensation
, which calculate corrections for accelerometers, gyroscopes, and magnetometers. Effective calibration typically involves averaging measurements over multiple orientations to minimize noise.
Core IMU Calibration Techniques
- Static Calibration (Bias Calibration): The IMU is held completely still to measure non-zero output when it should be zero. This isolates the gyroscope and accelerometer bias, allowing for simple subtraction.
