😱अक्षय कुमार हॉस्पिटलमध्ये भरती🙆‍♂️ - Reliable localization in GPS-denied, visually degraded environments is critical for autonomous UAV opera- tions This paper presents a systematic comparative evaluation of five V-SLAM systems ORB-SLAM3, DPVO, DROID-SLAM, DUSt3R, and MASt3RI spanning classical, deep learning, recurrent, and Vision Transformer (ViT) paradigms. Experiments are conducted on curated sequences from four public benchmarks (TUM RGB-D, EuRoC MAV, UMA-VI, SubT-MRS) and a custom monocular indoor dataset under five controlled degradation conditions (normal, low light, dust haze, motion blur and combined ), with sub millimeter Vicon ground truth. Results show that ORB-SLAM3 fails critically under severe degradation (62.4% overall TSR; O% under dense haze), while learning-based methods remain robust: MASt3R achieves the lowest degraded ATE.
