In-hand scanning with online loop closure

2009 IEEE 12th International Conference on Computer Vision Workshops, ICCV Workshops, 2009
We present a complete 3D in-hand scanning system that allows users to scan objects by simply turning them freely in front of a real-time 3D range scanner. The 3D object model is reconstructed online as a point cloud by registering and integrating the incoming 3D patches with the online 3D model. The accumulation of registration errors leads to the well-

An Improved Loop Closure Detection for RatSLAM

2019 5th International Conference on Control, Automation and Robotics (ICCAR), 2019
RatSLAM is a brain-inspired simultaneous localization and mapping(SLAM) system used to construct experience maps for environments, requiring odometry data and visual scenes in the path traveled. But it does not perform well in complex indoor surroundings due to the rough visual processing approach.

Invariant Spatial Information for Loop-Closure Detection

2019 16th International Conference on Machine Vision Applications (MVA), 2019
Recently, Bag-of-Words (BoW) has become a de-facto standard solution for loop-closure detection (LCD) in robotic visual SLAM (rvSLAM). Whereas BoW is efficient in using appearance information as invariant feature for comparing query and mapped scenes, it is not straightforward to use spatial information as invariant feature in BoW.

Loop closure via bond scaling and relaxation

Journal of Computational Chemistry, 1993
AbstractWe describe, test, and apply a new computational algorithm for generating protein loop conformations subject to distance and secondary structure constraints. The algorithm is based upon initial scaling and subsequent relaxation of covalent bond lengths.

Hierarchical Loop Closure Detection for Topological Mapping

2018
This chapter describes a novel appearance-based approach for topological mapping called HTMap (Hierarchical Topological Mapping), which is based on a hierarchical decomposition of the environment. Images with similar appearances are grouped together in locations, taking as a representative of the group the average of the PHOG global descriptors of the ...
