Abstract
Accurate robot localization in dynamic construction environments is vital for successful robotics implementation on jobsites. Dynamic Simultaneous Localization and Mapping (SLAM) methods show promise in addressing challenges by identifying and removing dynamic objects. However, existing studies struggle to accurately segment these objects, primarily due to handling unseen and temporarily static objects. This study presents a novel approach for robustly segmenting dynamic objects in construction environments. The approach captures potential objects using objectness masks and refines them by fusing masks with motion cues. The segmented information is propagated bi-directionally across frames. The method comprises four stages: objectness masks generation, motion saliency estimation, fusion of objectness masks and motion saliency, and bi-directional propagation of fused masks. Experimental results demonstrate the method's effectiveness in accurately segmenting dynamic objects and improving localization accuracy when integrated with SLAM structure, highlighting its potential for real-world applications in complex construction environments.
