Unsupervised Roofline Extraction from True Orthophotos for LoD2 Building Model Reconstruction

1 code implementation2 Oct 2023 Weixiao Gao, Ravi Peters, Jantien Stoter

However, using such point clouds for traditional plane detection-based methods can result in significant errors and introduce noise into the reconstructed building models.
