imu_utils analyzes the Allan Variance of IMU data, a technique used to quantify noise characteristics. This package enables users to evaluate the performance and stability of inertial measurement units (IMUs) by characterizing the noise present in gyroscope and accelerometer readings. The core problem addressed is the need for reliable methods to assess IMU sensor quality, which is crucial for applications like navigation and stabilization.
This project provides a practical implementation of Allan Variance analysis. It includes comprehensive documentation detailing the methodology and usage. The project's design facilitates easy integration with ROS systems. The provided sample data and launch files allow for quick experimentation and validation.
