A Right Invariant Extended Kalman Filter for Object based SLAM
Yang Song, Zhuqing Zhang, Jun Wu +3
With the recent advance of deep learning based object recognition and estimation, it is possible to consider object level SLAM where the pose of each object is estimated in the SLA…
Dynamic Reconstruction of Deformable Soft-tissue with Stereo Scope in Minimal Invasive Surgery
Jingwei Song, Jun Wang, Liang Zhao +2
In minimal invasive surgery, it is important to rebuild and visualize the latest deformed shape of soft-tissue surfaces to mitigate tissue damages. This paper proposes an innovativ…
Analysis of minima for geodesic and chordal cost for a minimal 2D pose-graph SLAM problem
Felix H. Kong, Jiaheng Zhao, Liang Zhao +1
In this paper, we show that for a minimal pose-graph problem, even in the ideal case of perfect measurements and spherical covariance, using the so-called "wrap function" when comp…
An observable time series based SLAM algorithm for deforming environment
Jingwei Song, Liang Zhao, Shoudong Huang +1
In this paper, we study the back-end of simultaneous localization and mapping (SLAM) problem in deforming environment, where robot localizes itself and tracks multiple non-rigid so…
Efficient two step optimization for large embedded deformation graph based SLAM
Jingwei Song, Fang Bai, Liang Zhao +2
Embedded deformation nodes based formulation has been widely applied in deformable geometry and graphical problems. Though being promising in stereo (or RGBD) sensor based SLAM app…
Linear SLAM: Linearising the SLAM Problems using Submap Joining
Liang Zhao, Shoudong Huang, Gamini Dissanayake
The main contribution of this paper is a new submap joining based approach for solving large-scale Simultaneous Localization and Mapping (SLAM) problems. Each local submap is indep…
Parallax Bundle Adjustment on Manifold with Convexified Initialization
Liyang Liu, Teng Zhang, Yi Liu +4
Bundle adjustment (BA) with parallax angle based feature parameterization has been shown to have superior performance over BA using inverse depth or XYZ feature forms. In this pape…
MIS-SLAM: Real-time Large Scale Dense Deformable SLAM System in Minimal Invasive Surgery Based on Heterogeneous Computing
Jingwei Song, Jun Wang, Liang Zhao +2
Real-time simultaneously localization and dense mapping is very helpful for providing Virtual Reality and Augmented Reality for surgeons or even surgical robots. In this paper, we…
