Traditional approaches to simultaneous localization and mapping (SLAM) rely on low-level geometric features such as points, lines, and planes. They are unable to assign semantic labels to landmarks observed in the environment. Furthermore, loop closure recognition based on low-level features is often viewpoint-dependent and subject to failure in ambiguous or repetitive environments. On the other hand,...
As to the morphological characteristics of the seismic damage of the interior ruins, this paper presents a map building mechanism by using the analytic hierarchy process and proposes a hierarchical simultaneous localization and mapping (SLAM) algorithm that is based on the hybrid metric-topological map. The architecture of the ruins-oriented SLAM system consists of three layers. In the intermediate...
