Building point cloud reconstruction in TomoSAR based on deep learning semantic segmentation

Electronics Letters, Volume 60, Issue 12, June 2024.
In this letter, we propose an SAR building point cloud reconstruction method based on deep learning point cloud segmentation. Leveraging the end‐to‐end processing advantage of deep learning, this method achieves automated and efficient detection of building point clouds.
