Semantic-Aware Predictive Mapping for Exploration and Navigation
This study addresses the ambiguity in exploratory navigation caused by purely geometric predictive maps, which struggle to distinguish semantically similar structures such as doors and walls. To overcome this limitation, this work proposes the first integration of an independent door channel into a predictive model, introducing semantic door cues to optimize predictive occupancy mapping. A dual-channel neural network is constructed based on the CogniPlan dataset and evaluated using a multidimensional assessment framework comprising L1 loss, F1 score, and IoU metrics. The proposed approach effectively enhances map completion in ambiguous regions and significantly improves local geometric inference accuracy. Experimental results demonstrate that the L1 error in door regions is reduced to 0.000025, with both F1 score and IoU reaching 1.0, substantially outperforming baseline models.
