Semantic mapping complements geometric modelling of a Mapping, localization and navigation are among the key robot's surroundings with semantic concepts, i.e., an understanding capabilities of autonomous systems. For robots to navigate of what the environment means to the robot. With safely in complex and evolving environments, mapping semantic mapping, these semantic concepts manifest as a can act as a unified framework that addresses multiple representation of the environment, thus lending robots more perception sub-tasks required for a higher-level scene understanding, resources for task planning and execution. The emergence of such as occupancy/traversability estimation, object semantic mapping can be attributed to (i) the limitations of detection and tracking. While some research streams employ purely geometric maps, and (ii) the advancements in deep end-to-end deep neural networks for mapless navigation via neural networks that allow semantic interpretation of raw imitation [1], [2], reinforcement [3], [4] or self-supervised sensory data [6].
