  • Choose Inertial Sensor Fusion Filters
    Applicability and limitations of various inertial sensor fusion filters.
  • Estimate Orientation Through Inertial Sensor Fusion
    This example shows how to use 6-axis and 9-axis fusion algorithms to compute orientation. There are several algorithms to compute orientation from inertial measurement units (IMUs) and magnetic-angular rate-gravity (MARG) units. This example covers the basics of orientation and how to use these algorithms.
  • Estimate Orientation with a Complementary Filter and IMU Data
    This example shows how to stream IMU data from an Arduino and estimate orientation using a complementary filter.
  • Logged Sensor Data Alignment for Orientation Estimation
    This example shows how to align and preprocess logged sensor data. This allows the fusion filters to perform orientation estimation as expected. The logged data was collected from an accelerometer and a gyroscope mounted on a ground vehicle.
  • Lowpass Filter Orientation Using Quaternion SLERP
    This example shows how to use spherical linear interpolation (SLERP) to create sequences of quaternions and lowpass filter noisy trajectories. SLERP is a commonly used computer graphics technique for creating animations of a rotating object.
  • Pose Estimation From Asynchronous Sensors
    This example shows how you might fuse sensors at different rates to estimate pose. Accelerometer, gyroscope, magnetometer and GPS are used to determine orientation and position of a vehicle moving along a circular path. You can use controls on the figure window to vary sensor rates and experiment with sensor dropout while seeing the effect on the estimated pose.
  • Custom Tuning of Fusion Filters
    Use the tune function to optimize the noise parameters of several fusion filters, including the ahrsfilter object. This example shows how to custom a cost function for various optimization goals.
  • Fuse Inertial Sensor Data Using insEKF-Based Flexible Fusion Framework
    The insEKF filter object provides a flexible framework that you can use to fuse inertial sensor data. You can fuse measurement data from various inertial sensors by selecting or customizing the sensor models used in the filter, and estimate different platform states by selecting or customizing the motion model used in the filter. The insEKF (Sensor Fusion and Tracking Toolbox)insEKF object is based on a continuous-discrete extended Kalman filter, in which the state prediction step is continuous, and the measurement correction or fusion step is discrete.
