DOC-SLAM: Robust Stereo SLAM with Dynamic Object Culling

Abstract

To improve the accuracy of estimating camera trajectory in dynamic scenes, this paper proposes Dynamic Object Culling SLAM(DOC-SLAM), a stereo SLAM system that achieves good performance by culling actual moving objects in highly dynamic environments. DOC-SLAM combines the semantic information from panoptic segmentation with the point features from optical flow together to detect potential moving objects. And a moving consistency check module is designed to determine and remove the feature points in objects which are in motion so as to accomplish dynamic objects culling. Besides, for enhancing the robustness of our system, we devise a key point supplement strategy to provide sufficient and reliable key points for tracking. Meanwhile, the trajectory and landmarks are generated for localization and mapping of robots. The experimental evaluation on public datasets demonstrates that our DOC-SLAM can fit highly dynamic scenes.
