Exploiting structural repetition for synthetic training data generation in LiDAR point cloud segmentation

Maintaining aging tunnel infrastructure requires inspection supported by digital tools such as Building Information Models (BIMs). Scan-to-BIM methods based on deep learning automate BIM creation from Light Detection and Ranging (LiDAR) point clouds. However, supervised training...

Iterative trocar-constrained laparoscope viewpoint search for enhanced surface coverage in 3D reconstruction

Abstract Autonomy is a growing trend in robot-assisted minimally invasive surgery. Autonomous systems require geometric information about the surgical environment, obtained from images and 3D reconstruction. The long-term goal of this work is to improve the completeness of endosc...
