New LiDAR sampling method improves 3D construction scene analysis

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new incidence-aware sampling strategy for individual LiDAR scans to improve 3D scene understanding in construction. This method addresses challenges like limited surface coverage and varying point density by mapping points to a normalized manifold space before voxel-based selection, while retaining original coordinates for downstream learning. Experiments using the SIP benchmark with Point Transformer and PointNeXt models demonstrated enhanced segmentation performance, particularly for non-planar elements and ladders, and reduced sensitivity to sampling resolution.

    Rethinking 3D Segmentation from Individual LiDAR Scans: Incidence-Aware Sampling on the SIP Benchmark

    arXiv:2608.07757v1 Announce Type: new Abstract: 3D scene understanding is increasingly important in construction, yet most methods are developed on curated datasets that do not fully reflect real site sensing conditions. In many workflows, individual LiDAR scans provide rapid loc…
