Georegistration Improvements Using ArUco Markers as Ground Control Points for Fast Deployment of 3D Map Reconstruction

open access: yesJournal of Robotics, Volume 2025, Issue 1, 2025.
Three‐dimensional map reconstructions provide representations of environments suitable for many robotics applications. However, the issue of scale error continues to hinder its practical applicability. This paper seeks to address this limitation by deploying advanced georegistration modalities integrated into the structure‐from‐motion (SfM) pipeline ...
