mola_imu_preintegration

A lightweight package for IMU preintegration routines, IMU data manipulation, and basic IMU calibration.

This repository provides:

• mola::imu::IMUIntegrator: A C++ class to integrate IMU accelerations and angular velocities.
• mola::imu::ImuTransformer: Transforms IMU readings from an arbitrary sensor pose to the vehicle reference base_link.
• mola::imu::LocalVelocityBuffer: Holds a short window of local velocities, accelerations, and global orientation, from external estimators and an IMU.
• mola::imu::trajectory_from_buffer(): Reconstruct a trajectory from a LocalVelocityBuffer.

Build and install

Refer to the root MOLA repository.
