Abstract

Abstract

En 中文
• Measure 3D detector degradation under systematically controlled LiDAR beam loss. • Generalize results by reporting statistics from repeated, randomized beam removals. • Derive VRU thresholds for the number of damaged beams and the best detector. • Compare effects across detectors, classes, and datasets. • Show beam-loss impact is location-sensitive and non-uniform across beams.
