L2M-Reg: Building-level Uncertainty-aware Registration of Outdoor LiDAR Point Clouds and Semantic 3D City Models
Ziyang Xu, Benedikt Schwab, Yihui Yang +2
Accurate registration between LiDAR (Light Detection and Ranging) point clouds and semantic 3D city models is a fundamental topic in urban digital twinning and a prerequisite for d…
Split4D: Decomposed 4D Scene Reconstruction Without Video Segmentation
Yongzhen Hu, Yihui Yang, Haotong Lin +8
This paper addresses the problem of decomposed 4D scene reconstruction from multi-view videos. Recent methods achieve this by lifting video segmentation results to a 4D representat…
General model for estimating range variances of terrestrial laser scanners based on (un-)scaled intensity values
Omar AbdelGafar, Selin Palaz, Yihui Yang +1
Recent advancements in technology have established terrestrial laser scanners (TLS) as a powerful instrument in geodetic deformation analysis. As TLS becomes increasingly integrate…
Quality-controlled registration of urban MLS point clouds reducing drift effects by adaptive fragmentation
Marco Antonio Ortiz Rincon, Yihui Yang, Christoph Holst
This study presents a novel workflow designed to efficiently and accurately register large-scale mobile laser scanning (MLS) point clouds to a target model point cloud in urban str…
