IMU Data Processing Program for Trajectory, Velocity, and Attitude Calculation

This program processes IMU data to calculate vehicle trajectory, velocity, and attitude, while generating plots of velocity versus Euler angles. The implementation involves reading accelerometer and gyroscope data from the IMU sensor, then performing numerical integration to derive vehicle velocity and position. The program utilizes sensor fusion algorithms (typically complementary filters or Kalman filters) to compute accurate attitude angles from the raw IMU measurements. The calculated velocity and Euler angles are visualized through MATLAB plotting functions, providing clear insight into the vehicle's motion dynamics. Additionally, the program includes data logging capabilities, allowing users to save processed results to files for subsequent analysis and processing. Key functions implemented include data acquisition from IMU interfaces, numerical integration methods for motion calculation, quaternion or rotation matrix operations for attitude estimation, and visualization tools for motion parameter display.
