IMU Calibration

IMU calibration involves adjusting an Inertial Measurement Unit (IMU) to ensure its measurements of motion—such as acceleration and rotation—are accurate. Over time, factors like temperature or manufacturing variations can cause a sensor's readings to drift or become biased. Calibration detects these errors by comparing the IMU's data against known references or during controlled conditions, and then applies corrections to ensure the measurements truly reflect real movement. Proper calibration is essential for precise navigation, motion tracking, or stability control in devices like drones, smartphones, or autonomous vehicles.
