ABSTRACT
Aiming at the demand for map expression in the human-robot co-existing environments, a multi-layer map including semantic grid map, semantic topological map and semantic concept map is proposed and constructed. Firstly, 2D LIDAR and RGB-D sensors are used to construct object semantic grid map combined with SLAM and object semantic segmentation method. Semantic topological map is then constructed using virtual door detection and Bayesian estimation method based on room and object containment relationships. Finally, according to the semantic grid and the semantic topological map, a seven-step ontology creation method is used to build a semantic concept map. The effectiveness of the proposed multi-layer map is verified by testing in multiple scenarios.

Topological and Semantic Map Generation for Mobile Robot Indoor Navigation
Intelligent Robotics and ApplicationsAbstractThe current tendency in mobile robot indoor navigation is to move from the representation environment as a geometric grid map to a topological and semantic map closer to the way how humans reason. The topological and semantic map enables a robot ...
Object-Aware Hybrid Map for Indoor Robot Visual Semantic Navigation<sup>*</sup>
2019 IEEE International Conference on Robotics and Biomimetics (ROBIO)In order to achieve an intuitive interaction and visual semantic navigation for the indoor robot, we propose a novel object-aware hybrid map. The existing map is usually a metric map, lacking semantics for interaction. We combine objects in the indoor ...
A flexible multi-layer self-organizing map for generic processing of tree-structured data
A new multi-layer self-organizing map (MLSOM) is proposed for unsupervised processing tree-structured data. The MLSOM is an improved self-organizing map for handling structured data. By introducing multiple SOM layers, the MLSOM can overcome the ...
