Tracking the 6DoF pose of arbitrary 3D objects is a fundamental topic in Augmented Reality (AR) research, having received a large amount of interest in the last decades. The necessity of accurate and computationally efficient object tracking is evident for a broad base of today’s AR applications. In this work we present a fully comprehensive pipeline for 6DoF Object Tracking based on 3D scans o...

INTRODUCTION This report presents a new imaging technique for non-invasive study of six degrees of freedom (DOF) knee kinematics during treadmill gait. MATERIALS AND METHODS A treadmill was integrated into a dual fluoroscopic imaging system (DFIS) to formulate a gait analysis system. To demonstrate the application of the system, a healthy subject walked on the treadmill at four different spee...

The reduced weight and improved efficiency of modern aeronautical structures result in a decreasing separation frequency ranges rigid elastic modes. Particularly, high-aspect-ratio flexible flying wing is prone to body freedom flutter (BFF), which coupling the short-period mode with 1st bending mode. Accurate prediction BFF characteristics helpful reflect attitude changes vehicle int...

This work aims to estimate 6Dof (6D) object pose in background clutter. Considering the strong occlusion and noise, we propose utilize spatial structure for better tackling this challenging task. Observing that 3D mesh can be naturally abstracted by a graph, build graph using points as vertices connections edges. We construct corresponding mapping from 2D image features filling fusion of featur...

Failure envelope formulations are typically employed to assess the ultimate capacity of foundations under combined loading and for incorporation in macro-element models. However, complex interaction between each load component, especially six degree freedom (6DoF) loading, means that determining satisfactory is often a process. Previous researchers have identified this difficulty as an obstacle...
