Example of rotating an object, not camera, using quaternion rotation. I was looking for ways to rotate an object, not the camera, in a 3d scene using a trackball like control. I found code on ...

A simple and efficient implementation of quaternion-based orientation tracking using the **MPU6050** IMU sensor and **STM32F4** microcontroller. This project also includes a real-time visualization ...

Abstract: The Cramér-Rao lower bound (CRLB) is a fundamental result in statistical signal processing, however, the CRLB for quaternion parameters is not yet established. To this end, we develop the ...

Abstract: In this article, the strapdown inertial navigation system/Doppler velocity log (SINS/DVL) is improved from the perspectives of mathematical model and data fusion algorithm. The optimized ...

Let $G$ be a finite, quaternion-free group with exponent $e$, let $F$ be a field of characteristic zero and let $\chi$ be an absolutely irreducible character of $G ...
