Lidar-based door and stair detection from a mobile robot

Abstract

We present an on-the-move LIDAR-based object detection system for autonomous and semi-autonomous unmanned vehi- cle systems. In this paper we make several contributions: (i) we describe an algorithm for real-time detection of objects such as doors and stairs in indoor environments; (ii) we describe efficient data structures and algorithms for processing 3D point clouds acquired by laser scanners in a streaming manner, which minimize the memory copying and access. We show qualitative results demonstrating the effectiveness of our approach on runs in an indoor office environment.
