PRISM-Nav: Pre-SLAM Integrated Scan Merging for Autonomous Wheelchair Navigation
Autonomous wheelchairs using 2D LiDAR suffer collisions with elevated obstacles that sit above the scan plane and remain undetected. Post-SLAM methods add camera-based 3D awareness to navigation costmaps but never update the occupancy grid map used for localization, creating map-costmap inconsistency that limits naviga...
