Angle Estimation of Simultaneous Orthogonal Rotations from 3D Gyroscope Measurements

Angle Estimation of Simultaneous Orthogonal Rotations from 3D Gyroscope Measurements

A 3D gyroscope provides measurements of angular velocities around its three intrinsic orthogonal axes, enabling angular orientation estimation. Because the measured angular velocities represent simultaneous rotations, it is not appropriate to consider them sequentially. Rotations in general are not commutative, and each possible rotation sequence has a different resulting angular orientation. N...

Simultaneous Orthogonal Rotations Angle

Angular orientation refers to the position of a rigid body intrinsic coordinate system relative to a reference coordinate system with the same origin. It is determined with a sequence of rotations needed to move the rigid-body coordinate-system axes initially aligned with the reference coordinate-system axes to their new position. In this paper we present a novel way for representing angular or...

Noncoherent 2d and 3d Sar Reconstruction from Wide-angle Measurements

This paper considers processing and visualization of radar scattering measurements from one or more wide-angle synthetic apertures. We consider both two-dimensional imaging and three-dimensional interferometric reconstructions. A point-scattering assumption is poorly suited to wideangle scattering; scattering objects within a target typically have narrow beam patterns, resulting in limited angl...

Orthogonal 3D-SLAM for Indoor Environments Using Right Angle Corners

Soon, in many service robotic applications, a realtime localization and 3D-mapping capability will be necessary for autonomous navigation. Toward a light and practical SLAM algorithm for indoor scenarios, we propose a fast SLAM algorithm which benefits from sensor geometry for feature extraction and enhance the mapping process using dominant orthogonality in the engineered structures of man-mad...
