Body Motion Capture Using Multiple Inertial Sensors
… which body movements can be captured by applying Euler angle based algorithms, specifically, single rotation order algorithm and the optimal rotation order algorithm. According to the experiment results of capturing ten ADLs, both the single rotation order algorithm and the optimal rotation order …

Exploiting quaternions to support expressive interactive character motion
… robustness, such as avoiding gimbal lock in the Euler angle representation. We show how to use quaternions and their exponential mappings to create distance metrics on character poses, perform simple statistical analysis of joint motion limits and blend multiple poses together. We demonstrate …

Development of Fault Tolerant Adaptive Control Laws for Aerospace Systems
… for aerospace systems that do not attain large angles and use exact feedback linearization of Euler angle kinematics. A proof of stability is presented by means of the circle Criterion and Lyapunov’s direct method. The second approach is intended for aerospace systems that can attain large …

Attitude Determination Using Imaging Lidar
… transmitted laser beam across the required solid angle. A lidar simulator was implemented to generate point clouds of digital 3D models. This thesis describes methods that can be used to detect features such as edges, boundaries, surfaces and corners in the point cloud. From those features it was …

Improving attitude determination and control of resource-constrained CubeSats using unscented Kalman filtering
… The quaternion estimates were converted to Euler angles to improve ease of interpretation. For the majority of the missions, the mean total Euler angle estimation error improvement ranged from 83% - 98% with error variance decreased by as much as 98%. One implementation had more than a two …

A hybrid type small 5-axis CNC milling machine
… typical serial and parallel machines such as Euler angle machines and the Hexapod. In particular, we consider singularities, reversal characteristics, and manufacturability. We show that hybrid machines can benefit from the advantages of serial and parallel mechanisms while avoiding most …

Viewpoint estimation in medical imaging
… space. Several 3D rotation methods such as Euler angle, axis-angle, and quaternions are investigated for viewpoint representation. The results demonstrate that viewpoint estimation in medical imaging can be effectively solved using CNN-based classification and regression models. The …

Articulated Statistical Shape Modelling of the Shoulder Joint
… and internal rotation) were generated using Euler angle sequences. The ASSM of the model was built using principal component analysis and validated. The validation results show that the model adequately estimated the shape and pose encoded in the training data. Developing ASSM of the shoulder …

On the motion of a symmetric rigid body with a "yo-yo" despin device attached
… vectorial methods of Newtonian mechanics. The Euler equations for a rigid body are used to describe the motion of the rigid body itself. The moment acting on the body through the tension in the yo-yo cables is unknown and it is necessary to apply the second law of Newton to a despin weight so …

Looking for a Simplicity Principle in the Perception of Human Walking Motion
… based on a model of 15 rigid body segments with Euler angles and a Cartesian translation for each. Both of our schemes are principal component (PC)-based implementations of a norm-based multidimensional object space – a type of model for high level perceptual schemes that has received attention …
