Attitude Reconstruction from Inertial Measurement: Mitigating Runge Effect for Dynamic Applications

چکیده
Time-equispaced inertial measurements are practically used as inputs for motion determination. Polynomial interpolation is a common technique of recovering the gyroscope signal but subject to fundamentally numerical stability problem due Runge effect on equispaced samples. This paper reviews theoretical results phenomenon in related areas and proposes straightforward borrowing-and-cutting (BAC) strategy depress it. It employs neighboring samples higher-order polynomial only uses middle segment actual time interval. The BAC has been incorporated into attitude computation by functional iteration, leading accuracy benefit several orders magnitude under classical coning motion. would potentially bring significant benefits navigation sustained dynamic motions.

متن کاملAn Inertial Measurement Framework for Gesture Recognition and Applications
We describe an inertial gesture recognition framework composed of three parts. The first is a compact, six-axis inertial measurement unit to fully capture three-dimensional motion. The second, a gesture recognition algorithm, analyzes the data and categorizes it on an axis-by-axis basis as simple motions (straight line, twist, etc.) with magnitude and duration. The third allows an application d...
متن کاملVelocity-Aided Attitude Estimation for Helicopter Aircraft Using Microelectromechanical System Inertial-Measurement Units
This paper presents an algorithm for velocity-aided attitude estimation for helicopter aircraft using a microelectromechanical system inertial-measurement unit. In general, high- performance gyroscopes are used for estimating the attitude of a helicopter, but this type of sensor is very expensive. When designing a cost-effective attitude system, attitude can be estimated by fusing a low cost ac...
متن کاملInitial Attitude Estimation of Tactical Grade Inertial Measurement Unit for Airborne Environmental Camera
The initial attitude estimation of the airborne navigation system greatly affects the overall attitude accuracy. The initial alignment depends on the inertial measurement unit’s performance. In the case of the tactical grade inertial measurement unit, even though tilt angles can be estimated relatively accurately by using accelerometer outputs, it is difficult to determine the azimuth angle wit...
