3D Reconstruction of Monuments from Drone Photographs Based on The Spatial Reconstruction of The Photogrammetric Method

Abstract

Due to their efficient flight control systems and their camera of high quality modern drones can fly precisely and take aerial photos of high resolution. Although these multi-rotor devices are not able to fly long distances yet, they are very efficient instruments for taking aerial photographs of their proximate environment. As they are able to float and rotate along their vertical axis to a discretionary direction, they can be used for monitoring and taking pictures of a building from several directions. If pictures are taken of a building from all directions with significant overlap (of at least 50%) the 3D reconstruction of the building in a photogrammetric way becomes possible. The reconstructed models do not only contain the spatial forms but also the visualinformation based on the snapshots. As a result of the entire reconstruction a virtual object is gained in the virtual space that can freely be accessed and visible from all directions by enlarging or reducing the size. A virtual collection can be established for monuments, historical buildings or other spectacular objects worth recording. The objects of the collection (buildings) are lifelike and can be perceived and studied by anyone. The 3D models, of course, cannot substitute the photographs of high resolution but they can complement them in the collection.

Leading-Edge Technologies for Architectural Design: A Comprehensive Review

“…Aerial imaging significantly contributes to project documentation and marketing efforts in architectural design. Drones capture high-quality photographs and videos showcasing completed projects from unique perspectives (Casella et al, 2022;Chen et al, 2021;Molnar, 2018;Cunha et al, 2022;Ryan et al, 2022;Maxwell, 2022). These visuals are instrumental in creating compelling portfolios, marketing materials, and presentations for architects and developers.…”

Application of Surveying and Mapping Technology in Disease Extraction and Analysis of Stone Monuments

“…It can be used of measuring, mapping, and modelling the size, shape, and spatial location relationships of natural geographical elements. Recently, surveying and mapping technologies represented by 3D laser scanning (Thamir, Abed, 2020), close-range photogrammetry (Hou, Bu, 2019), UAV oblique photogrammetry (Molnar, 2018), multi/hyperspectral (Cerra et al, 2018) and industrial cameras (Guo, 2017) have developed rapidly. By the characteristics of non-destructive and high-precision, it is gradually being applied to the detection, extraction, and analysis of stone monument diseases.…”

Information Fusion for Cultural Heritage Three-Dimensional Modeling of Malay Cities

“…Each type has its own limitations, advantages, and costs. However, data from the mobile-based platform, known as a mobile laser scanner (MLSs), have been widely used in urban planning and applications with certain advantages, including urban land cover analysis, digital 3D city modeling, urban environment monitoring, and autonomous vehicle driving [19,[37][38][39]. MLS data are collected by using laser scanners positioned in mobile vehicles.…”
