Abstract:

The ability to detect corridor-like structures is essential for autonomous mobile robot navigation in indoor environments. In this paper, we present a novel method for real-time corridor detection using a single depth camera. Our aim is to find a corridor just by looking at walls, even if there are some objects inside, such as a trash can or a chair. Once the corridor has been determined, the robot can be moved smoothly along the hallway semi-autonomously with simple commands without hitting the walls. The proposed work combines layers of occupancy maps extracted from Point Cloud into one final occupancy grid map, where 2D Hough Transform is applied to extract the lines corresponding to the corridor walls. The method has been tested on a real robot using Mynt-eye depth camera. The experimental results show the reliability and efficiency of the proposed technique for navigation tasks in corridor-like unknown environments.
