Design and Simulate Inertial Navigation Systems
Pose estimation and localization are critical components for both autonomous systems and systems that require perception for situational awareness. Fusing data from multiple sensors and applying fusion filters is a typical workflow required for accurate localization. Sensor simulation can help with modeling different sensors such as IMU and GPS. Moreover, simulated data can be used to augment the data recorded or streamed from inertial sensors. Further, you can use filters to fuse individual measurements to provide a better result. You can tune these filters based on the sensors and the end-application.
Through several examples, we will cover:
- Modeling sensors, tuning filters and calibrating IMU measurements with Allan Variance
- IMU, GPS, altimeter, and wheel encoder sensor fusion for inertial navigation
- Pose estimation from asynchronous sensors fusing accelerometer, gyroscope, magnetometer and GPS
- Automatic filter tuning to find optimal noise parameter values
- Visual-inertial odometry using synthetic data
