SplitFusion: Simultaneous Tracking and Mapping for Non-Rigid Scenes

no code implementations4 Jul 2020 Yang Li, Tianwei Zhang, Yoshihiko Nakamura, Tatsuya Harada

We present SplitFusion, a novel dense RGB-D SLAM framework that simultaneously performs tracking and dense reconstruction for both rigid and non-rigid components of the scene.

FlowFusion: Dynamic Dense RGB-D SLAM Based on Optical Flow

no code implementations11 Mar 2020 Tianwei Zhang, Huayan Zhang, Yang Li, Yoshihiko Nakamura, Lei Zhang

Dynamic environments are challenging for visual SLAM since the moving objects occlude the static environment features and lead to wrong camera motion estimation.

ZMP support areas for multi-contact mobility under frictional constraints

2 code implementations12 Oct 2015 Stéphane Caron, Quang-Cuong Pham, Yoshihiko Nakamura

We show that, in the LPM, having the ZMP in the pendular support area is a necessary and sufficient condition for contact stability.

Stability of Surface Contacts for Humanoid Robots: Closed-Form Formulae of the Contact Wrench Cone for Rectangular Support Areas

1 code implementation20 Jan 2015 Stéphane Caron, Quang-Cuong Pham, Yoshihiko Nakamura

Here we argue that the CWC can be explicitly computed without reference to individual contact forces, and give closed-form formulae in the case of rectangular surfaces -- which is of practical importance.
