- 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
tunefunction to optimize the noise parameters of several fusion filters, including the
ahrsfilterobject. This example shows how to custom a cost function for various optimization goals.
- Fuse Inertial Sensor Data Using insEKF-Based Flexible Fusion Framework
insEKFfilter 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)
insEKFobject 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.
- Binaural Audio Rendering Using Head Tracking
Track head orientation by fusing data received from an IMU, and then control the direction of arrival of a sound source by applying head-related transfer functions (HRTF).
- Estimating Orientation Using Inertial Sensor Fusion and MPU-9250
This example shows how to get data from an InvenSense MPU-9250 IMU sensor, and to use the 6-axis and 9-axis fusion algorithms in the sensor data to compute orientation of the device.
- Wireless Data Streaming and Sensor Fusion Using BNO055
This example shows how to get data from a Bosch BNO055 IMU sensor through an HC-05 Bluetooth® module, and to use the 9-axis AHRS fusion algorithm on the sensor data to compute orientation of the device. The example creates a figure which gets updated as you move the device.
