A ROS package written in C++ that analyzes IMU performance by computing Allan variance from stationary sensor data. It estimates gyroscope and accelerometer white noise and bias instability parameters, outputting YAML values and Matlab-drawn figures.
Use cases
- characterize IMU noise parameters for sensor fusion
- compute Allan variance from a two-hour stationary IMU recording
- estimate gyroscope white noise and bias instability
- generate calibration YAML files for VINS or SLAM pipelines
- compare noise performance of different IMU models
- analyze rosbag-recorded IMU data offline
When to choose
- you use ROS and need IMU noise parameters for visual-inertial navigation
- you want a C++ Allan variance tool with Matlab plotting scripts
- you need standard gyr_n/acc_n/gyr_w/acc_w values for filter tuning
When to avoid
- you need a non-ROS standalone tool
- you want fully automated plotting without Matlab
- you need real-time IMU calibration rather than offline analysis
