HPGS-SLAM: Hybrid Point-Guided Dense Visual SLAM With Online Mapping via Gaussian Splatting

In this letter, we introduce HPGS-SLAM, a real-time RGB-D SLAM system guided by hybrid point features (combining traditional and learned point features), enabling high-precision tracking and online dense mapping with photorealistic reconstruction. HPGS-SLAM consists of two main components: (1) a lig
