Abstract:

We present a novel approach for place recognition and loop closure detection based on binary codes and disparity information using stereo images. Our method (ABLE-S) applies the Local Difference Binary (LDB) descriptor in a global framework to obtain a robust global image description, which is initially based on intensity and gradient pairwise comparisons. LDB has a higher descriptiveness power than other popular alternatives such as BRIEF, which only relies on intensity. In addition, we integrate disparity information into the binary descriptor (D-LDB). Disparity provides valuable information which decreases the effect of some typical problems in place recognition such as perceptual aliasing. The KITTI Odometry dataset is mainly used to test our approach due to its varied environments, challenging situations and length. Additionally, a loop closure ground-truth is introduced in this work for the KITTI Odometry benchmark with the aim of standardizing a robust evaluation methodology for comparing different previous algorithms against our method and for future benchmarking of new proposals. Attending to the presented results, our method allows a fast and more effective visual loop closure detection compared to state-of-the-art algorithms such as FAB-MAP, WI-SURF and BRIEF-Gist.
