Tutorial on rigorous sensor fusion
© 2022 EPFL
Two researchers of EPFL-TOPO together with Dr. Ismael Colomina from Geonumerics have given a tutorial on Dynamic Networks on June 5, 2022, at the ISPRS Congress in Nice.
Dynamic Networks (DN) present a rigorous, 1-step solution for registration of optical sensors with the support of navigation data. This approach has multiple advantages in comparison to the current multi-stage fusion methodology due to its ability to mitigate the effect of observation errors directly at the sensor level. In turn, this improves the quality and fidelity of obtained geospatial models, such as elevation models, orthophotos, 3D point-clouds or digital-twins in general.
The tutorial was organized by the ISPRS WG I/9 Integrated Sensor Orientation, Calibration, Navigation and Mapping presided by MER Jan Skaloud.
The online implementation of the Dynamic Network (https://odyn.epfl.ch) is supported by ENAC-IT4research.
