The project is forked from here, and I only add some commens.

The C++ IMU-TK Library (Inertial Measurement Unit ToolKit) provides simple functions and data structures to calibrate MEMS-based inertial navigation units, and to process and display IMU data. IMU-TK implements a multi-position calibration method that does not require any parameter tuning and simply requires the sensor to be moved by hand and placed in a set of different, automatically detected, static positions. IMU-TK also provides a collection of functions for data integration.

The code is tested on Ubuntu 14.04. IMU-TK requires the following tools and libraries: CMake, Eigen3, Ceres Solver, OpenGL, QT and Gnuplot. To install these required packages on Ubuntu, use the terminal command:

#!bash

sudo apt-get install build-essential cmake libeigen3-dev libqt4-dev libqt4-opengl-dev freeglut3-dev gnuplot

and follow this guide to install Ceres Solver.

To build IMU-TK on Ubuntu, type in a terminal the following command sequence.

#!bash

cd imu_tk
mkdir build
cd build
cmake  ..
make

Test the library with the test_imu_calib app (binary in /bin, source code in src/test_imu_calib.cpp): test_imu_calib performs an IMU calibration given the data included in bin/test_data/:

#!bash

./test_imu_calib test_data/xsens_acc.mat test_data/xsens_gyro.mat
