Remote Sensed Data and Processing Methodologies for 3D Virtual Reconstruction and Visualization of Complex Architectures

Resumen

The topic “Remote Sensed Data and Processing Methodologies for 3D VirtualReconstruction and Visualization of Complex Architectures” is a growing subject thatinvolves many different disciplines, such as architecture, cultural heritage,engineering, archaeology, and virtual reality. The increase is driven by the currentavailability of new sensors for remote acquisition along with open and big datasources. Despite availability and advances at sensor- and data-level, there is aneed for reliable, affordable, and powerful methods and tools for realizing photorealistic, metric, re-usable, and semantic-aware 3D products. In this challengingand inspiring transition, the scientific community is putting great effort to design,research, develop and validate novel easy-to-use, ease-to-learn and low-costframeworks for 3D modelling and further understanding of real environments.This book originates from the ISPRS/CIPA 3D-ARCH workshop “3D VirtualReconstruction and Visualization of Complex Architectures” which was held in Ávila,Spain in February 2015. The workshop brought scientists, developers andadvanced users in photogrammetry, computer vision, 3D modelling, and relatedtopics to present and share their latest advancements and achievements.This book brings together 19 peer-reviewed contributions from variousauthors, including extended papers presented at the 3D-ARCH workshop,covering topics related to the 3D virtual reconstruction and visualization ofcomplex scenarios. Due to the high transversality of 3D and intra-sectoralapplications, the key topics addressed in the book are: aerial photogrammetry,especially focused on the low-altitude remote sensing images which takeadvantage of classical platforms, stressing the automated processing stages of datasegmentation and dense point cloud generation; terrestrial photogrammetry, as afundamental technique for architectural heritage documentation, with all latestimprovements in the automated 3D reconstruction pipeline; multi-sensor fusion,as a solution for a broad spectrum of applications and solutions, encompassingpathological mapping, urban-scale analysis, and optimization of orthoimagegeneration, solar panel installation, and surveying of complex architectures;3D modelling, which covers the modelling procedures involved when usinggaming sensors, while producing building information models (BIM), or forprocedural building modelling; structural analysis, focused on reverseengineering and finite element modelling (FEM) for stability evaluation andconservation measures.
