Two-Dimensional LiDAR SLAM with Multi-Resolution Distance-Field Matching, Adaptive Keyframes, and Loop Closure

In two-dimensional laser SLAM exploration and mapping in complex indoor environments, scan matching is sensitive to the initial pose, error accumulation, and redundant map updates. To address these issues, an MDF-ALC-SLAM method is proposed. Firstly, a multi-resolution distance field is constructed at the front end, an...

Multi-Agent Cooperative Navigation Algorithm Based on Trajectory Optimization with Global Structural Constraints and Attention-Enhanced Graph Neural Networks

To address the challenges of formation maintenance, collision avoidance, and cooperative navigation for multi-agent systems in shared environments, a spatio-temporal trajectory optimization method under global structural constraints and A attention-enhanced graph neural network (AE-GNN)-based cooperative navigation str...
