Rethinking the semantic classification of indoor places by mobile robots
🤖 AI Summary
Traditional indoor semantic segmentation typically assigns a single label to an entire room, failing to capture the complex coexistence of multiple functions in real-world spaces. This work proposes a novel paradigm that permits semantic ambiguity within rooms by modeling functional distributions at the regional level, thereby offering a more realistic representation of indoor scene structure. By moving beyond the restrictive “one room, one label” assumption, the approach enhances semantic understanding for service robots operating in complex environments. The effectiveness of this method is validated through object search tasks, where it significantly improves both task success rates and environmental adaptability.

📝 Abstract
A significant challenge in service robots is the semantic understanding of their surrounding areas. Traditional approaches addressed this problem by segmenting the floor plan into regions corresponding to full rooms that are assigned labels consistent with human perception, e.g. office or kitchen. However, different areas inside the same room can be used in different ways: Could the table and the chair in my kitchen become my office? What is the category of that area now? office or kitchen? To adapt to these circumstances we propose a new paradigm where we intentionally relax the resulting labeling of semantic classifiers by allowing confusions inside rooms. Our hypothesis is that those confusions can be beneficial to a service robot. We present a proof of concept in the task of searching for objects.
