SDFA-Net: Urban Manhole Cover Detection via Fisheye Image and LiDAR Point Cloud Fusion

Automated manhole cover detection, a key task in urban infrastructure inspection, is hindered by modality-specific limitations: conventional monocular image-based detectors do not directly quantify cover-to-road elevation differences, LiDAR-based methods suffer from sparse sampling that limits recall for small, distant...
