An indoor service robot can establish a 3D map of the environment by a visual sensor. When the robot uses the established map again, there is a situation that the robot's view is in a new position and the relative position of the map can not be obtained. A relocalization algorithm based on multi-dimensional map information is proposed to solve the problem. Based on the established 3D environment map,...
In this work, in order to improve spatial recognition abilities for the long-term operation tasks of the assistant robot for the elderly, a novel approach of semantic region estimation is proposed. We define a novel graph-based semantic region descriptions, which are estimated in a dynamically fashion. We propose a two-level update algorithm, namely, Symbols update level and Regions update level....
