Abstract:ABSTRACT:As cultural sector practice becomes increasingly dependent on digital technologies for the production, display, and dissemination of art and material heritage, it is important that those working in the sector understand the basic scientific principles underpinning these technologies and the social, political and economic implications of exploiting them. The understanding of issues in cultural heritage preservation and digital heritage begins in the education of the future stakeholders and the innovati… Show more
“…For instance, expensive terrestrial laser scanners are very rare in higher education institutions of those countries. In addition, a strong interdisciplinary approach should be followed since these technologies are relevant in many other subjects such as civil engineering, machine construction, cultural heritage or informatics (Hess, Garside, Nelson, Robson, & Weyrich, 2017).…”
Section: Virscan 3d Scanning Simulator As An Educational Toolmentioning
We are presenting a Terrestrial Laser Scanner simulator - a software device which could be a valuable educational tool for geomatics and engineering students. The main goal of the VirScan3D project is to cover engineering digitisation and will be solved through the development of a virtual system that allows users to create realistic data in the absence of a real measuring device in a modelled real life environment (digital twin). The prototype implementation of the virtual laser scanner is realised within a game engine, which allows for fast and easy 3D visualisation and navigation. Real life objects can be digitised, modelled and integrated into the simulator, thus creating a digital copy of a real world environment. Within this environment, the user can freely navigate and define suitable scanning positions/stations. At each scanning station a simulated scan is performed which is adapted to the technical specifications of a real scanner. The mathematical solution is based on 3D line intersection with the virtual 3D surface including noise and colour as well as an intensity simulation. As a result, 3D point clouds for each station are generated, which will be further processed for registration and modelling using standard software packages.

“…The experimental part has a fundamental role in teaching and knowledge transfer, from remote sensing to surveying activities. Researches on the application of smart approaches to such fields are so increasing in the last years, that all of the already cited approaches have been tested (Kosmatin Fras and Grigillo, 2016;Kravchenko et al, 2016;Hess et al, 2017;Ahlqvist and Schlieder, 2018;Haugsbakken et al, 2019;Gil-Docampo et al, 2019). The common goal is to actively involve students in the process of learning, by iterating field and class work, supported by multimedia tools, like videos, games, tutorials, MOOCs, and so on.…”
Section: Teaching Geomatics With Smart Educationmentioning
Abstract. The democratization and accessibility of low-cost devices for image acquisition and the development of highly automated procedures for orientation and dense image matching allow almost every person to be a potential producer of photogrammetric models. The diffusion of image-based technologies to produce 3D models amongst wider audiences entails however some risks, as the lack of critical awareness of the final quality of the outputs. Information and education about potentialities and limitations of reality-based digitization by photogrammetry may help spreading procedures and methods for the correct use of this technology. This paper presents the results of one of the funded projects within the 2018 ISPRS Capacity Building Initiatives “Education and training resources on digital photogrammetry”. The production of multimedia material for supporting smart educational teaching and learning approaches will be reported, as well as experiences on their application on case studies. Blended innovative teaching and learning pedagogical approaches have been tested, as Flipped Classroom (FC), Learning-by-doing (LBD), Collaborative Learning (CL), and Challenge-Based Learning (CBL), supported by multimedia tools for capacity-building and knowledge transfer. The implementation of multimedia materials for supporting teaching strategies resulted in the production of updated and engaging resources, as videos, tutorials, and datasets to be used during courses, workshops, and seminars targeted to different user groups. The combination of teaching strategies and multimedia supporting materials were tested within national and international projects, from academic courses to complete non-experts, from activities on the field to online and distance learning.
“…This approach challenges the students to develop new knowledge and understanding through interaction with objects, based on a prior understanding (Smith, 2016). Clear successful examples of this kind of educational initiatives comprising 3-D scanning can be encountered in subjects like arts and cultural heritage (Hess et al, 2017) or geology (Dabove et al, 2019;Fernández-Lozano & Gutiérrez Alonso, 2016).…”
Abstract. The advent of the smartphones brought with them higher processing capabilities and improved camera specifications which boosted the applications of mobile-based imagery in a range of domains. One of them is the 3-D reconstruction of objects by means of photogrammetry, which now enjoys great popularity. This fact brings potential opportunities to develop educational procedures in high schools using smartphone-based 3-D scanning techniques. On this basis, we designed a Project Based e-Learning (PBeL) initiative to introduce secondary students to the disciplines of photogrammetry through the use of their mobile phones in an attractive and challenging way for them. The paper describes the motivation behind the project "D3MOBILE Metrology World League”, supported by ISPRS as part of the "Educational and Capacity Building Initiative 2020" programme. With this Science, Technology, Engineering and Mathematics (STEM) initiative, we implement a methodology with the format of an international competition, that can be adapted to daily classwork at the high school level anywhere in the world. Therefore, the championship is essentially structured around a collection of well-thought-out e-learning materials (text guidelines, video tutorials, proposed exercises, etc.), providing a more flexible access to content and instruction at any time and from any place. The methodology allows students to gain spatial skills and to practice other transversal abilities, learn the basics of photogrammetric techniques and workflows, gain experience in the 3-D modelling of simple objects and practice a range of techniques related to the science of measurement.
