Abstract

En 中文

• UDA method for DL-based instance segmentation of bridge point clouds under class imbalance and distribution shifts. • Automated pipeline for generating synthetic bridge point clouds with accurate instance-level annotations. • Class-balanced dynamic thresholding enabling adaptive self-training based on confidence distributions. • Consistent accuracy gains across four real-world datasets without manual annotations.
